I recently finished a tasty squad of BA death company. I went outside and sprayed them with purity sealant. When I got back in I immediately noticed that they had that damn foggy hazy finish to them because of the humidity in the air. Having this on the background of black armor is probably the worst, most noticable mistake ever! Can someone help me remedy this without ruining my hard work....

1) throw away GW Purity Seal because it is absolute garbage...

2) go buy some Testors Dull coat.

3) you can either gloss them first then dull-coat, or just hit them with dull-coat... either will fix it, but the latter will be really, really matte.

This has come up before, I believe the solution was respray with gloss coat.

EDIT:

Don't buy Testors Dull Coat. It is non-archival, which mean it is not resistant to UV rays, which means that your lovely models will start to yellow after 3 years, which means that by 5 years they will look brown-ish. Which means your lovely paint-job will be ruined, and you will have to either strip your models or by new ones.

Not fun.

I've never heard that about Testors Dull coat... none of my stuff has faded yet, but they are always in cases when I am not gaming.

I wonder if Krylon clear has the same results.

Krylon clear is "Archival", so no yellowing. The gloss does excellent with humidity; but the flat does not. My solution:
Spray with 2 coats of gloss. Shoot with flat and immediatly bring into AIR-CONDITIONED room. *Ari-conditioners keep rooms cool by removing the humidity from the air.*

I second the cover in gloss varnish - Brush on GW 'ard coat works for me.

Then I use Vallejo matt spray to dull it back down.

I've had the same problem with Purity seal.

I'll never use it again!

Brother Bart: how is that Vallejo Matte, does it do a decent job of killing the gloss?

It is unusual to be below 80% humidity in Australia. <3 AU

It does a great job. I'll never use anything else. 'Nuf said!

This is why i dont use spray on
I tend to use the paint on bottles of gloss and matte. (gloss seals it better, then the matte coat afterwards helps to get rid of the shine)

So let me get this straight, If I paint a mini, then leave it 3 years it will go brown??
Thats pretty worrying...

Thanks for all the advice. I dont htink I will go with the Testors brand. I need to find some other gloss coat that is archival. I never had this problem until I moved to Texas....just another reason to add to the plethora of things that I hate about the South! I want to spend as little money as possible to solve this problem. I have ard coat....but I dont want to brush on (dont want potential brush strokes) so I will find some gloss coat. Since, Ive started spraying in the guest room of the house....it has been working out spectacular! So, to recap, for anyone living in high humidity areas, spray indoors....the results are day and night in comparison!

I guess if what he says about UV is right then you could just keep your models in those little (or big) plastic display cases. Plastics are generally opaque to UV so that should protect them.

Prevention:

1. Go to www.weather.com

2. Type in your zip code.

3. On the Overview tab, click on "Click for Dew Point, Humidity, and more."

4. If the humidity is greater than 50%, it's a bad day for spray priming or spray matte coating. DON'T DO IT!


Looking at the 10-day forecast, my area doesn't go below 67% humidity for the next 10 days. Nor has it for the past 8 day. I have 10 minis that need dull coating and I really want to start on my Super Heavy for Apoc games. But, I can't. I will not have brush strokes on my super heavy after all of the work I've put into it, so I have to wait for another 2 weeks to spray it.

Been using Dullcote for more than 3 years and none of my models have changed colour in any way.

There can be problems for stuff like that, here on the shores of Lake Ontario, it's always over 50% humidity, usuaslly in the 70%+ range. So I always Prime in my basement, where there are constantly two dehumidifiers running. Don't worry, it's faily open, with a couple of fans running for ventilation so the fumes don't get to me, and I put extra cardboard boxes laying flat against everything close to make sure I don't spray anything by accident.

I always check the hourly humidity where I live with a website called wunderground.com weather underground. If you put in your zipcode and click on the icon for the day it will give you the hourly. I never spray when it is over 50% humidity. I also emailed my local weatherman at the news station and he had some pretty interesting information about certain times of year have better humidity than others and that the day undergoes what is called a diurnal cycle, so it starts high, goes lower then goes high. I recommend you do the same with your local weatherman in texas because I am in california as he/she may have some good advice.

Back to the present, I had the same problem with a batch of 20 red skinks. Here is what I did and 90% of the grey went away.

Spray with gloss varnish fairly closely.
See magic happen
Half way through the drying process, hit it again.
Half way through this drying hit again
repeat as needed

The reason this fixes the problem is that the gloss varnish has a strong solvent in it and when the spray hits the model it starts to eat that layer of varnish, which is why you need to spray so much of the gloss.

This technique fixed my temple guard

If you want a matt finish you can then spray over the top of the gloss. Personally I use the army painter as the gw stuff used to be okay then they messed it all up a few years ago.

Thanks for all the great info form everyone. I know these threads come thru like once a month it seems...I was just to lazy to dig for one, so I started a new one.

Now my second question....Is there a particular brand of gloss varnish anyone recommends? I only have a comic store that sells GW supplies exclusively and a pretty selective Hobbytown USA in the area. Also Michael's craft store

Same here. However my models arent exposed to heavy UV like direct sunlight, that might make a difference.

I have tried the Krylon dull and gloss...both are terrible in high humidity, esp the gloss. However, I am in Florida, and our summer humidity tops 85-90% quite easily.

Overall Ill have to put my vote for Dullcote...Ive used it for many years under all kinds of conditions and never had any issues.

Yeah, I'd assumed that we weren't keeping our painstakingly painted models on the window sill or in a tanning salon.

I've used dullcote for years also and never had any color change, but my models are also not in the sunlight so I don't know if that would make a difference.

Odd. I've clear coated in 95% humidity at 90+ degrees with no problems with Krylon. I've also used Krylon at below zero and in the rain and no problems.

For semi-gloss or gloss I use nothing but Krylon. For matte, matte I use Dullcoat.

For my gloss coat I use future brushed or airbrushed on.

For matte, Testor's Dullcote is the only way to go.

As for the archival nonsense...unless you are leaving your models in direct sunlight for 8 hours a day, you will not have any problems. 15 years of using dullcote and not a single yellowed model.

Gloss coat then testors worked for me, click my name and look at my threads to find the pertinent one, it was a miraculous recovery -

Amen to that! even the undercoat paint will dry foggy (i.e black spray turns grey) let alone the sealants.

Best to do it in an air-conditioned area or one with an extraction fan above it I find.

I've used Humbrol Acrylic Matt varnish spray with no problem until the other day, then..................... white clouding all over the latest batch, F**K.
On the good side unlike GW varnish this was repairable with a simple application of gloss varnish.

Beware - Doll Cote also suffers from humidiy
