I sprayed out a hood yesterday with basecoat clear and put a run on the front of it, so I wet sanded the whole panel smooth with 1200 this morning and flow coated it with 2 coats HS clear with a little extra reducer this time getting some debree in it,so i need to sand and buff it. My question is if you recoat clear inside of a say 24 hour window does it actually bond to the 1st session of clear meaning if I buff through the clear I just put on will i see an edge from the first session of clear. thanks jim
If it's just a single panel (hood) then don't try to blend clear, just wet-sand it (I use 500) and shoot the entire panel with clear.
With 2 coats of clear on you shouldn't buff through it. If you get some dirt in clear just sand the little spec out. The hood in the pics is on a off topic truck but same principle: First all the body work was done. Filler primed, block sanded. Sprayed non sanding sealer. Base coat applied. I had to wet sand the base coat to get out some small little specs. I used 1000-1200 for this. Then sprayed the clear. There's only 2 coats of clear on here also. There were a couple small dirt specs but 1200 wet sanded took them off. I didnt sand the whole hood. (Then I'd have to buff the whole hood-more work) Maybe too much info for you. Maybe it'll help somebody else... Goodluck
The first thing you should have done was not to sand the whole panel, the problem was with the run so focus your corrective action there. There would have been no problem with spraying the next coat of clear on top of the previous coats, it takes far longer than a day for the clearcoat to cure and thereby requiring an additional scuff. BTW, 1200 grit is not enough tooth to make a difference anyway. I learned a great tip from Kevin Tetz on how to correct runs...take a look at his Paintucation videos, especially the one on color sanding.
