interior painting muck up

[eternazr4]

hey there, sorry no pics, very shortly though..

well progress on the tamiya r34 ztune has been going well, i'm painting the interior at the moment, but i've really messed things up:

Spraypainting the interior semi-gloss black, i thought i'd mask it up, and paint the inserts flat red, but brush paint like a few coats (enamel xf-7) to bring the red up to colour, silly silly silly idea, the red paint is really lumpy looking, and i feel like giving up.

Assuming the worst, i'd have to strip back everything to bare plastic, primer and mask off, so that the flatred has a nice white surface to be applied on. Are there any easier ways? lol

The paint you brushed on is lumpy did you say? Was it fine before you put it on? I dont want to send you in the wrong direction, so answer those and Ill respond. But before I respond, I bet the AF modeling maniacs here will respond lol..

Thanks for your reply

prior to painting the flat-red, the surface was smooth, painting red over a black surface was a very dumb idea, but i thought by applying a few coats (brushed) it would eventually bring out the red. 4 coats later its all lumpy, i thinned the enamel enough so that it flowed smoothly, but it just ended up all blotchy. Does anyone have any ideas to resolve the problem before i end up stripping everything back?

cheers

all i can think is if the paint was fine as you painted it, maybe the black wasn't completely dry?

but because it's enamel, you MIGHT be able to carefully apply some turps and thin it out. only apply a small amount at a time, and in thin even coating. then brush with a clean brush.

that might work, but it is risky, it could ruin the black paint, make the red run, or it could melt the plastic, so be very careful if you use it.

try other, safer, methods first, use this as a last resort before stripping.

got the problem sorted, ended up using a blunt tooth pick to scrape the paint off, it ended up flaking off taking the semigloss blackspray paint with it, so now there is a gray base to paint red over, which will be much easier than painting over black - now why didnt i use primer to begin with lol

Yeah when I screwed up on my valve cover, I took a exacto knife and scraped off what I messed up on and started over. Glad you fixed it.

If you want a brighter red, try painting white (paint that is, no need for primer here) on whatever surface you want, then red over the white.
