I just tried Testors Lusterless Flat rattle can. The kit had been sealed, with Dull Coat and another coat of Future on top of it. The rattle can stuff burned right through the paint, with one light pass. Am I doing something wrong or should I stick to the bottled stuff?

Sounds like you have applied a rattle lacquer with acetone as a vehicle onto what amounts to some acrylic surface (Future) - and there was a reaction.

What a bummer!

I'm guessing that the reaction you have seen is pretty "stock-model" for this type of mix - maybe someone can address the real question of what paints / layers may be safely covered with this stuff and identify the cases where one should not use this product? Sounds like it's a "no-no" on Future!

I have had Testors rattlecan Dullcoat and Glosscoat destroy well cured Gunze Sanyo acrylic paint finishes, so much so that if I paint something with Gunze I have to put a note with the kit so I dont do it again!

I dont think I have had the problem with testors finishing products on top of already sealed paint coats though.

I wouldn't touch that testors stuff with a 10 foot bargepole...WAY too aggresive. I use the modelmaster acrylic matt varnish mixed with a little semi gloss and a retarder shot through an airbrush as a final coat. The retarder helps avoid the 'white powder' problem and generally it works well but even then you have to be careful to avoid build ups.

Sounds like a safe bet, but I haven't had any problems with the TESTORS or TAMIYA Lacquer-based Spray-Flats personally, since I religiously follow my own set rules when using them. I just might try your method to see how I like it, though... Who csays you can't teach an old dog new tricks?

PS- I've heard other modellers complain about the use of TAMIYA bottled ACRYLIC FLAT shot through their airbrushes- I understand that the bottled TAMIYA CLEAR GLOSS, CLEAR SEMI MATTE and CLEAR FLAT are meant to be used as ADDITIVES to their other bottled paints... ???

PPS- What are you using as a "retarder"?

Badger ACCU flex extender though I don't know if that's still available, I've had my bottle for years and it's almost run out. I also have some Liquitex Flow Aid as a back up but I havent tried it yet

Might be wise to contact Testors and see what they have to say--show them the picture, too.

I COMPLETELY agree with Edmund! You can still use TESTORS DULLCOTE and LUSTERLESS FLAT on future projects, provided that you use TESTORS MODEL MASTER II products...
