Post painting tidy up help

Postby RAZA » Mon Feb 20, 2006 9:16 am

I've just painted my GTZ, it's looking mint, but due to not having a booth I have a couple of little bits of dust showing in the clear coat, and I'm wondering what the best way of getting rid of them is...

Currently i'm thinking really fine sandpaper and then a cut and polish but any other suggestions would be appreciated.

The paint is 2 pack.

Thanks

2 pack paint without a booth ?

take a few close up shots of it if you can

if its not to far under the surface you might get away with a cut and polish

but if its a few layers deep theres probably not much you can do
Nothing to see here ...

even with a booth you get little bits of crap in the paint.

Your idea is right, you want to wet sand it back with very fine paper, around 2,000 grit with a sanding block, then give it a cut + buff with increasingly fine cutting compound. Be VERY careful not to go through the clear coat, because it will show up no matter what you do and you'll have to re-clear it to hide it, if it's a metallic finish underneath you'll have to redo the metallic also! This is why it pays to give a decent number of coats of clear, so you have plenty of meat to cut back and buff

There is almost an art to buffing without getting swirl marks, the main thing to remember is to keep the surface wet so you don't heat it too much, don't apply too much pressure, and make sure you wait atleast a weak from the application of the last clear coat before buffing!

thanks, thats a great help.

Is it possible to wet sand it with very fine paper then apply another coat of clear?

yep, if you're going to give it another coat then don't bother going too fine, 800 should be plenty.
