This is the result of rattle-can aplication of Testors Dullcote four days after applying Future. The Future was applied over Tamiya acrylics. There was an oil/turpentine wash twenty-four hours before the Dullcote application. It was raining outside on the day I sprayed the Dullcote! I tested it on a junk piece with no problem! And, the speckles do not appear on the sides of the fuselage.
The Dullcote was misted on from about ten inches away; several coates until wet!
Mineral Spirits does not seem to cut it. Laquar thinner does cut it; and everything else. So far the best approach seems to be to lightly sand it untill it is gone.
Shipwreck, I’ve had similar issues to this before and I thought it was as a result of a lacquer based product over the acrylic base coat. If it looked wet, I think its too much, the dullcoat sits on top and eats away at the acrylic. I’ve done it again since (used dullcoat over acrylic) but very very lightly, never enough to look wet, over about 6 coats. To be honest, not sure how to fix it, short of stripping. Mine remained spotty. Regards,
Ouch. I had a similar thing happen using a Polly Scale acrylic varnish, and someone suggested I go over it again with Future. It worked, the mottling/frosting disappeared and I used a different flat coat (Xtracrylix IIRC) for the final finish. Whether another coat of Future would negate the effects of the lacquer flat coat (or seal it in permanently) I don’t know… Hope you can resolve the problem.
Shipwreck, I had a similar problem back around 1989, I used the spray can Dull-Cote over Gloss-Cote after decaling my Monogram Harrier. I had lot’s of little dimples or small divots all over the flat surfaces of the plane. Believe me, it looked like hell! I’m fairly sure that the cause of my problem was laying on a too heavy coat of the Dull-Cote. This little episode, along with the issue of the lacquer smell, was one reason I changed to acrylic gloss and flats. Maybe a light sanding would help? Good luck brother!
I use Tamiya acrylics exclusively with testors dullcote over the top. Each coat of dullcote needs to be very light, just a couple passes and then let dry. What I am seeing on your photo is that it was applied to heavily in one coat. Been there, done that.
I’ve had similar problems in the past using Dullcote spray cans on rainy & humid days. Dusting it on from a distance away actually works against you by allowing the spray to pick up more moisture.
I use my airbrush 99% of the time for clear coats and have an inline moisture trap, but still avoid spraying on rainy days.
That’s not “bad” Dullcoat… “Bad” Dullcoat will leave a whitish-looking residue embedded in the paint… Or it won’t go “flat” completely and stays kinda semi-gloss in places… But that usually only happens with older cans that weren’t thoroughly shaken…
Well, There’s yer problem, right there ! [;)] Apply Mist coats only, and let it “flash” (meaning when it just starts to look dry) between passes…
Laquer thinner is cutting it because it’s (the Dullcoat) laquer… Pretty hot stuff…
Testor’s Dullcoat is designed to go on over Testor’s enamels… Ya takes yer chances with other paints and brands… I’ve always gotten great results with it over Testor’s enamels (which is what I use 90% of the time), but it’s kinda dicey when you get into other brands, especially over acrylics, like Future (get rid of that stuff!)…
Acrylic laquers, on the other hand, don’t like some enamels… I’ve used Tree House acrylic laquer clear flat from rattle-cans over different brands of acrylic paints without any problems, but God help ya if put it on over Tru-Color or any other enamel gloss spray-paint… It attacks it without mercy…
I’ve never had a dullcoat go bad over any paint. I use testors airbrush exclusively. I thin it with a standard lacquer thinner and spray light semi dry coats. The key is a fast dry. Doesn’t give the lacquer time to bite at the paint. Future btw is not as hard as most acrylic paints. Seems like most problems I’ve seen are from people using future for the gloss coat. Good luck with the fix and kill your rattle can! Use the bottled stuff, much, much better control…
As RedCorvette said, watch out for rainy days (fortunately a rarity where I live). In the distant past, I’ve tried painting on rainy days before I knew better (I primarily brush paint) and have had the paint do funny things. Once or twice with that and I quickly learned to leave the paint on the shelf during wet weather.
