Triaros: Purity seal failure.


That's right. I have frosted my Triaros. Coldest night this year and a quick spray this year has really done a number on me. 

Looks great when I breath hot air on it and drench it with water, but otherwise I have a serious problem. 
Now; have you ever encountered this problem? I have received a series of great solutions on our Facebook page so I will endeavour to sort this without paint stripping it. 

Stay tuned and please comment below.

  1. I've read of a few ways to fix this. The most common agreed upon seems to be giving it an airbrush coat of Future Floor Polish(I believe this is called Klear over in the UK), and then re-applying Dull Coat.

    Really, if you have an airbrush at your disposal(one of the bunnies HAS to have one?!), I'd highly recommend ditching aresol based sealants and just making use of that airbrush. My general sealcoating philosophy is: give it a coat or two of Klear as a protective coat, and then airbrush either testors dullcoat or more recently either Vallejo Matte Varnish or Minitaire Matte Varnish.

  2. Regnirok,
    Do you use the future floor polish straight out of the bottle? Todd over at sincain40k uses that as his pre wash sealer (then testors dull later I believe).

    I've had the same think Drake, so it's good you are posting this. I'm curious to see your solution!

    1. Greg,
      Yeah, I spray it straight out of the bottle. I use that stuff for just about everything: prior to oil and acrylic washing, prior to decal placement, as my harder "more protective" layer prior to dull coating. It's pretty fantastic stuff and can even be used in small quantity to make very nice acrylic washes using any standard acrylic paint.

  3. I have had this happen before. Never use gw purity seal. It is terrible for this. Testors dullcoat is a brilliant substitute (buy from firestorm games in uk). Gloss varnish should get rid of the frosting. I painted on vallejo gloss and that did the trick

    1. Just FYI, testors dullcoat can frost over too. We've had it happen to a few people here, as we live in a fairly humid environment. It's something that happens with aresol based sealants in certain climates(namely in humidity). GW purity seal just seems to be more prone.

  4. Can someone explain what frosted is to me? :)

    1. Frosted is where purity seal creates a cloudy effect instead of clear.

  5. Could be worse, a friend liberally sprayed his tin of purity seal on his newly painted model to find that he had picked up his chaos black undercoat by mistake.

    I am with the other readers, I don't use gw varnish. Testers is very reliable and gives a good finish. Klear is excellent as a gloss varnish, but if you get any moisture in it as you put it in on, it can go a milky colour. Vallejo air varnishes are also good and a lot cheaper than GW.

    With regards your issue, I am not sure the application of a new gloss varnish would work completely as the frosting will still be in place. Would it be useful to try and wash the varnish layer off in some way, warm water with some form of product applied via a cotton bud on the worst areas?

    Good luck

  6. This sounds odd I know but it works perfectly I promise you, olive oil (presumably other oils work just as well but I haven't tried them as yet) painted over the affected surface completely eradicates the frosting and lasts over time as well.

    I came across that little nugget in some dark corner of the internet and thought I'd give it a go in a desperate attempt to fix a commission piece I'd spent a lot of time on and was more than a little surprised at how well it worked :)

  7. Sorry to hear this. I recently just fixed a ton of frosted models. Just hit it with some 50/50 Isopropyl/water combo out the airbrush. If that doesnt fix it hit it with some Testor model masters semigloss. :)
