I used GW purity seal last night, luckily it came out ok but I tried it a second time on a random piece of sprue that had been primed and painted and it frosted real bad.
I was wondering how to "prevent" this less it happens to one of my models.
Is there any other type of finish that would produce the same look as the purity seal (when it doesn't frost)? I'm mainly looking for something that is reliable -not too shiny or dull. It's a pity GW's frosts up occasionally, I really like the appearance it makes otherwise.
Mainly I wanted to know if the frosting effect was controllable (namely by changing temperature, distance of spray, or coverage) if I could somehow eliminate frost?
I would like to know some of your techniques for varnishing sucessfully.
Also, since I live along coastal Texas, Humidity is high. How big a role will this play in the frosting?
Peel label off GW can. Buy can of Krylon Crystal Clear. Glue label on. Purity seal that doesn't fog up!
More seriously, pretty much every complaint I can remember seeing from people about purity seal frosting up on them comes from a part of the world with high humidity. Around here, "high" is over 50% and I have never personally known anyone who had a problem or complained about it.
i was told to shake it A LOT before use, even more than u would shake a can regularly
are we talking about it frosting after the fact because humidity is too high?
or frosting as it's drying thus drying to a frost?
Mostly drying to a frost, I sprayed inside last time, and the temperature was 74 degrees F.
Humidity is an issue because if I spray outside (in warmer weather -I heard that helps) then the humidity becomes a pressing concern.
Today in Austin Texas, the Humidity was 61%.
frosting happens because the can is too warm or too cold, i was told that if you spray your models and then notice frotsing appearing, spray them again straight away!
Spraying again right away can eliminate frosting?
Out of curiosity, what is this supposed ideal temperature to spray purity seal at? Is it the temperature of the can or the model that needs to adhere to the temperature parameter?
thats what ive been told, fortunatly ive not had the bad luck to of had to find out yet
id have thought the ideal temperature would be about room temperature (about 26-27c), too much higher or too much lower and it'll frost, same with all the spray paints, whenever i have some models needing spraying i always nick a thermonitor from downstrairs and keep it in my room for a period near my cans, then ill only spray if the temp is looking good
I usually spray indoors at about 77 Degrees F.
I keep having frosting on occasional test sprues...
Does dullcote from testor's ever chalk up?
