Subject: Valkyrie Canopy fogged up from dullcote, quick fix?
So, I sprayed a couple Valkyries with glosscote first to prevent any fogging when I sprayed dullcote, and it fogged up anyways, I tried to spray clearcote over it to maybe remedy the problem, and it didn't fix it, I need quick fixes to this problem! Also, the rest of the model frosted up from the dullcote as well. :(

Ok folks, my problem is actually that the canopies are frosted, not fogged, any help would be appreciated, everything so far has not worked in removing it. (Windex, Olive oil, and Simple green bath)

I don't think there is really anything you can do at this point, short of replacing the canopy, and you can get one on eBay for a couple of dollars.
In the future, be sure to mask any clear parts before you spray any kind of varnish on the model.

My suggestion is to say f* it, and just paint the canopies black or dark grey. If you own an airbrush, make it go from black to dark grey (and maybe medium grey at the end), and it will just look like tinted glass.
Or email GW and beg for new bits.

You mean the varnish has caused it to go frosted? It's hard to say without looking at it in person, but you could dip it in floor finish. If it's very rough, you could sand and polish it first, then dip it in floor finish.
You can see how people use polishing + future floor finish on canopies here...
@Skink -- is it possible to polish plastic canopies? I've never given it a fair try, but I failed miserably when a plastic canopy frosted up years (decades?) ago -- due to superglue fumes -- and everything I tried made it worse.
It's all good though; it turned into a lesson of caution, and since then, I've been very careful with canopies.

Yes, you can polish plastic canopies (I'll qualify it by saying I don't know if all canopies are made from the same plastic, maybe there's some weird plastics you can't polish, but the ones I've tried it works fine). It's pretty common practice among those who make scale model aircraft.
I've never tried polishing out superglue fumes, I imagine you can though.
If you have a scratch or mould line on a canopy that you want to remove, sand it off (using the finest sandpaper you can use and still remove it) then work your way up to super fine grit sand paper and finally polishing compounds + foam or cloth polishing pads. You can't get it perfect just with polishing though, at least I've never been able to get it perfect, lol, always still have a few swirl marks or faint scratch marks when the light hits it in a certain way. That's why you dip it in future Future Floor Wax when you're done to give it a nice shine.
I imagine you could use the same process to remove superglue frosting. Maybe try some mild solvents first though? I've luckily managed to avoid superglue frost on clear plastic so I've never had to learn how to deal with it.
With acrylics you can also do flame polishing, but I've never tried that on an actual canopy, only on sheets of clear acrylic. It may or may not work on your typical plastic canopy (and I wouldn't recommend it if there's other substances on top of the plastic causing the frosting as I imagine it'd end badly!).

They'd often use silver polish (very fine abrasive) to do it. So it IS possible to buff the scratches/fogging off, but it will take some effort.
You can get plastic polishing compounds from auto parts stores, it's used to restore headlights. I have also used toothpaste and it seemed to work (using a dremel with a polishing wheel, wouldn't try doing that super fine polish by hand).
If you look up headlight restoration and acrylic aquarium restoration you'll find some stuff as well for polishing clear acrylics.
But you only need to polish it as far as is needed for a floor finish to work. You'll really struggle to polish it perfect (I won't say "never", but I have yet to get to get something I've been 100% happy with, I think case modders and acrylic fish tank aficionados are less fussy than I am with models, lol).

I haven't had a problem in a long time, because since that happened I've been a lot more careful with using not too much superglue, and I let it dry out in a way that it can breathe. Also, more recently, I've switched to a more expensive superglue that's guaranteed not to frost.
If it does ever happen again, though, I'll try to fix it just cuz!

Ok, so let me detail what happened in chronological order.
Sprayed canopy with glosscote, dried, then switched over to dullcote, fogged. after 24 hours, I sprayed with a matte sealer (different to glosscote) and it frosted...
I really can't afford to buy replacements right now, but I may have to... does anything dissolve glosscote/dullcote/sealer?

In the future, be sure to mask any clear parts before you spray any kind of varnish on the model.
And that's an auction, not a buy it now...
I need to purchase canopies, there are TWO Valkyries that have ruined parts I need replacements for. :(

Have you tried isopronoal alcohol? usually takes off lots of things without hurting plastic. use higher than 95% for best results.

I put a bit of 95% alcohol in the SG mixture to help dissolve things, and it hasn't worked, I'll have to get some it seems. Any other things help dissolve but don't hurt plastic?

Simple green changed formula a while back.
just use the 95% it self
if you are putting it into SG which is mostly water all you are doing is diluting its POWER!
try a little cup of it and dunk it in then rub it off with a fine cloth.

Dullcote and Glosscote are both lacquers and they probably aren't going to come off, no matter what you do, unless you use a chemical paint stripper and scrub it off (which will ruin the tiny plastic piece.
Like I've said, either buy a new canopy for a few dollars, just paint over it, or leave it alone.

I can't buy two new ones from your link, that's an auction, not even guaranteed to get the part I have to fight for it, then there's the OTHER Valkyrie I have to buy a part for...
I need two clear sprues, and I need to buy them from a store, not ebay, only one on ebay is an auction for one sprue. I can't even flat out buy it.

I understand that it is an auction, but if you want a replacement canopy, it's probably going to be your only option. There isn't a "store" that sells just the piece you need outside of eBay stores (which is where that auction is located). Wait until the end of the auction and try to snipe it and then wait until they repost another one (it's how eBay stores that auction bits do business).
You can try contacting GW customer support, but there is no guarantee that they'll send you replacement pieces. However, it could be worth a try so I would suggest sending them an email to find out.
Seriously, at this point painting over it or trying to buy a new one are pretty much your only options. Simple Green, isopropyl alcohol, or Windex aren't going to remove two coats of lacquer. Like has been previously mentioned, you can try wet sanding with progressively higher grit sand paper and then buffing the clear parts with 12000 grit sanding sponge but it's going to take a lot of work. If you don't already have the material to do it with you'll probably end up spending more money to buy it all than if you just bought new ones from the eBay auction I linked to you.

Then your only option is to try and sand/polish the pieces, but I wouldn't expect too much from it since you are trying to sand off two coats of lacquer. It isn't going to be quick or easy and there's a good chance it will be all for naught.
If it is a commission you need to contact your client and explain the situation to him/her and lay out the options and them him decide how to proceed.

Well then you're screwed. Sometimes there just isn't a good answer to a problem and you have to accept the loss. Consider it a lesson for the future: don't spray matte varnish on clear parts.
There is no such thing as a hobby without politics. "Leave politics at the door" is itself a political statement, an endorsement of the status quo and an attempt to silence dissenting voices.

Subject: Valkyrie Canopy fogged up from dullcote, quick fix?
Have you tried the isopropyl alcohol yet? Use a high % IPA (90% or more, we can get 99% in hardware stores over here pretty cheap, don't dilute it with other stuff). I know that it can remove small amounts of dullcote, don't know how well it'll remove several layers of glosscote and dullcote as I've never tried it.
If that doesn't work you could try cellulose thinners, Testors/Humbrol airbrush thinners (the variety for enamels) or turpentine or white spirit. I've seen tutorial videos from Humbrol where they use their enamel thinners to soften an enamel varnish (for the sake of weathering techniques)
WARNING: I have no idea what any of this will do to clear plastic, I've never tried it on clear plastic, I recommend trying it on a test piece first.
If none of that works, sanding is your next option like I mentioned above. I have already posted a couple of links, here's another one...

I'd say if you don't want frosty canopies, don't ever spray cockpits with any kind of varnish, be it matte or gloss. Mask them off if you want them to stay nice and clear.
