After you guys are done with the second round of clear are you starting out with 400 for you cut and buff? I usually do the 4 coats followed by 800 up wet and I never go through the clear. I'm blocking with 12" durablocks and rolls of 800/1000 grit paper before I switch to the sheets of finer paper and a soft block. I'm a little uncomfortable getting 8 coats of clear on sharp body lines or panel edges.
Now if I get an occasional run or sag and have to 400 the panel and start over then I suppose I flow coat but my cut and buff is the same procedure so it doesn't look any different than 4 coats and a cut and buff.
I was wondering the same thing Brad. I'm trying to understand this process. How does 8 coats of clear work over sharp edges and body lines? And aren't you defeating the purpose if you start blocking with anything less than 400? If you are trying to get rid of the "urethane wave"? Personally I've sprayed stuff with 3-4 coats, wet sanded with 600 then gone back with 3 more and wet sanded with 800-1200-2000-3000 trizact and 5000 trizact and been happy with the results. I know what JimC said but I've never noticed any urethane wave after blocking it with 800 then moving on with the finer grits.
