lacquer clear coats

Yeah, they are the same oil paints used for oil painting and by some figure painters. I use oderless mineral spirit spirit to thin. It's not a very agressive solvent so it won't damage the underlying acrylic base coat. Don't use airbrush thinner for sure. Make sure the acrylic base layer has cured before you do the wash. And yes, it does eventually dry. How long does it take? I don't know, never was bored enough to watch it dry but definitely less than a month, maybe a few days. It's near the last state of finishing the model so I just let it sit and get back to putting a dullcoat over it when it's dry. The technique I use is to wash the panel line with maybe 90% thinner 10% paint into the panel line, then use a cotton swab to wipe the wash off trying not to soak up the wash that's in the panel line. After sealing the wash with dullcoate I do final weathering such as applying pastel and drybrushing. then seal again with a final dull coat.

oil based paint for panel lines?
do they ever dry? and what kind of thinner would i need to use? terpintine?
if so, would terpintine eat away, or destroy the acrylic base coat? since water can even harm this stuff.
i haven't used oil based paint before though. are they the same as oil paintings done by the old masters? those things take up to a month to dry.
i might even paint my base coats in enamel next time.

I haven't had any problems with acrylic clear coats going over anything, be it flat, gloss or different types of paints. I've also had no trouble using Testors dullcoat over acrylic paints, never tried it over enamels or lacquers but don't think that would be a problem.

Why don't you think about using an oil based paint for panel line washes? This why you don't have to worry about your acrylic base. Oil also has the advantage for panel line washes of having a longer working time.

yeah, i have heard about future and how good it is.

but my problem was doing panel lines. if my base coat is acrylic, then i can't seem to draw in the lines with the same base coat. or else, i can't clean the messy parts with thinner. the base coat will just be destroyed.

i wanted to use lacquer paint from the first place, but i don't know where to get em. and the ones that i do know of, comes in a spray can. i usually like to mix colors and use airbrush. so this will be a pain to use.

so i wanted to use lacquer clear coat, if it doesn't yellow and if it doesn't damage the acrylic base coat, then i would want to purchase one.

does anyone know if different clear coats over each other can cause any harm? if i put flat clear coat acrylic over gloss lacquer coat? i guess i should just go wit lacquer flat.

Why not use Future Floor Wax? It is clear acrylic paint in all actuality.

You can spray lacquer over acrylic but it has to be done in several light dust coats to provide a barrier between the acrylic and the wet coats of lacquer that you will apply after the light dust coats.
I have heard people say that Testors Clearcoat and Dullcoat yellow with age but I have yet to see it. Maybe some of the more seasoned builders here could give you some furthur info.
