Cotton fibers in clearcoat over base kandy.

Hello i was painting a fender in my garage. The first coat of clear came out like a mirror i let it sit for 15 min and shot the second coat. When i was done with the second coat i looked at the top of the fender and saw that there was alot of little cotton fibers(maybe from by shirt). I shot both of the coats really wet so is it possible to just wet sand the cotton out and clear without shooting the base again. I used Chromaclear over HOK kandy apple red base (not the translucent Kandy).

What grit sand paper should i use?

No i used tack cloth. i was wearing an old work shirt made of cotton i believe thats were the cotton come from.

Well i ended up wet sanding with 1200 and the fibers came out pretty easy. Now now another question can i skip the reclearing part and just buff it? The 2 coats of clear i sprayed were pretty wet and thick.

I'd try buffing it. 1200 is not all that agressive, and if you put two pretty good coats of clear on there, you should have some room there and leave enough mil protection on.

Worst case scenerio, if you did end up going thru the clear into base trying to buff it out, your not really in too much of a different place then if you recleared it now. other then having to spot in some base in the cutthrough area, and reclear the rest of the panel. Not all that difficult, if the color you sprayed is what I think it is, solid red ford candyapple color. A true candy on the other hand would be much more difficult to spot in.

Biggest concern if you did burn through buffing and have to repaint, is possible lifting at the burn through area when you spray on the new base, but spraying a little epoxy sealer on that area first and allowing to sit for awhile or better yet overnight and wetsanding smooth, would eliminate that concern. But you shouldn't really have too much of a problem getting 1200 to buff back out if you really applied two good coats of clear like you said you did. I haven't used Dupont products for many years, but chromaclear is not a cheap clear. Not all clears are created equal though, and some cheaper low solids clear, and you could be in trouble trying to buff much back out with only two coats applied.

What kind of masking paper are you using; the green paper can degrade when solvents hit it; causing fibers in your paint job; use good masking paper when painting and green for primering. Not saying this is what happened to you, but it can happen in general.
