Hey guys!

I never had a problem with frosting, but during the latest sealing session 1 of my models got hit by too much purity seal.
Now it looks like it just came out of a snowstorm....

I googled solutions and tryed waiting 24h and then put another thin layer of seal other the model, but with no result :/

any ideas?

Purity seal is satin?

The usual way to fix frosting is to hit it with a gloss varnish first to dissolve and cover the matting agent and then finish off with another coat of satin/matte to take away the shine.

hmm will that still work even though I added a second layer of varnish?

ps: yes, its satin.

I think it would probably still work, but I can't say for sure because I've never tried it. Fixing frosting is very hit and miss, sometimes the frosting goes away easily other times it's really persistent.

I'd make sure it's not the can of satin you're currently using that caused the problem, before you spray another model with it, test it on something you don't care about and see if that also frosts up.

Satin and matte varnishes are made by adding a matting agent, a powdery substance, to an otherwise glossy varnish. Frosting is that matting agent become visible because it has separated out, either because there's too much of it or because some other conditions caused it to separate out before it cured fully.

I have used mineral spirits to help take it off, but you have to be careful as it can take paint off as well if you use too much. I also have a hellpit abom that got too much purity sealer, or it was simply too humid at the time (one reason I stopped using sprays at all).

Also don't use a really good brush, you want a soft one but not one you are going to use for something else. I did a lot with a q tip.

Remember frosting often happens when you spray a flatter varnish when its hot outside. (ie the varnish dries partially in the air before it hits the model). May want to keep this in mind as well.

Paint over wity olive oil, leave overnight. Wash gently in warm, soapy water.

for real?

I've tried the oil trick on one model that frosted, I found it didn't really work all that well. When you apply it, the frosting goes away, but when I came back to clean it off it just looked even worse. I ended up just applying a gloss coat after cleaning off the oil and that fixed it.

Some people say it works, I wonder if maybe my model was frosted worse than theirs.

Maybe the oil allowed a gloss coat to fix it

~spooky~

I have had a lot of success with olive oil. After washing it off, I just re-spritz Dullcote in warm, dry conditions.

I bought a really dodgy batch of Dullcote, so I got a fair bit of practice. Testors was actually able to replicate the frosting in their lab and I got sent some compensation.

I've also had decent results with the olive oil. I applied a bit and brushed the model to help it take off the frosting, before washing with a bit of detergent to take off the oil.

I frosted my DV Chosen and an Harlie jetbike last year. It wasn't pretty. Cause was the humidity. Contacted GW and they sent me an entire replacement DV boxed set and jetbike box but didnt have any solutions. I tried everything. The olive oil method was a dead loss. The gloss varnish worked well but gloss varnish is a bit thicker and seemed a bit noticeable. Best fix I found was brush on matt varnish. The stuff I used was Jo Sonja's Matt Varnish. Made in Oz apparently so not sure how available it is in other countries (I got mine here in Korea btw)

One remedy is to brush on gloss varnish (like Vallejo Polyurethane) and then brush on a satin varnish or medium. I've rescued a couple of models this way. You wan to keep it thin, no matter what you do though (if it's a paint job you care about), because all those layers of varnish really add up on the model.

So, to determine the truth of the matter, we must invent a time machine so that we may transport Skink can go back in time and tell younger Skink NOT to use the oil, and see if the model is still frosted. But then he wouldn't post here that the model was NOT not fixed by not applying olive oil before the gloss coat. And then we wouldn't invent the time machine. Oh noes....!
