Proper application of touch-up paint ... how?

[dud]

I recently bought some TU paint to cover some small chips on my car. The paint cam in two (2) containers, the first with the base coat, the 2nd with the "pearl" (clear) topcoat.

I read the instructions (online) which stated that I should apply a number of thin basecoat applications and once dry apply a few thin topcoats.

Sounds easy, right?

I followed the directions and slightly sanded the basecoat with 1200 grit SP. I then applied the topcoat (per instructions ... and within seconds the application started to disolve the three coats of basecoat!

Anyone here ever SUCCESSFULLY apply this type of TU paint? I'd appreciate (and am always open to) some friendly advice.

Thanks ...

maybe you could try putting each coat of the base coat on, let each coat dry for a few days, and then after a week or so add the clear coat?

Or maybe use a (very adjustable) heat gun to bake the paint on?

It sounds like you were doing it right, but no mention of how much drying time you gave it or what type of conditions the paint was under (humidity level, temperature, etc)

touchup paints are a pita. I'd let each coat dry more and see.

My car is tri-coat (basecoat, midcoat, clearcoat). Makes touching up a real bitch.

That's weird. Skip the top coat maybe?
Make sure you have some nice rubbing compound ready too, and it should look like new again.

can't really skip a top coat, the clear maybe...

The clear is the topcoat.

With his dual stage touch up kit it was ambiguous.

The basecoat is almost pure white and really stands out against the rest of the paint. The topcoat is needed to "tone down" the basecaot and give it the "pearl" lluminescence.

I'll give it another try but I am a bit disappointed in two areas: first, the wet sanding. When I sand the basecoat with 1200 grit the grains come off in the paint. Second, the topcoat disolving the basecoat ... and I am using very little paint.

Grains? Is your paint metallic or solid?
You can't get a nice even surface with the wetsanding? If so, just buff it out and it should look good again.
