OK, started my first model car this weekend, the Tamiya Morris Mini Cooper 1275s. This was a "trainer" car, something to start and learn on. I sprayed on plain old Tamiya gloss red, X-7, a few thin coats until it got nice and even. Let it dry overnight, and applied the decals (with a little difficulty, but that's another matter). After the decals had dried, I sprayed with with a super quick mist coat of rattle can gloss from Tamiya. It was definitely a mist coat, not real heavy, no drips or anything. It took almost no time for the paint underneath, especially the paint in crevices, to eat away and show the primer underneath (see attached photo).
So what did I do wrong? Need to wait longer for paint to gas out before clear coat? Avoid Tamiya clear and use something else? Need some guidance. Sorry if this is repeat question, thanks in advance for reading and helping!
