I'm sure there will be other input on this but here's mine...36-40 for the welds and old filler(grinder) 80(on a hand block) to shape new filler working your way to 180 before primer. And I like 320(some like 400) under base coats. Then you can do 600 between clear coats if you choose to do that. Then 1500-2000 before buffing..Just be sure not to oversmooth between products because they all need something to hook up to.Always use a hand block if you don't want waves.Keep in mind the timeframe for fillers, they sand very easily when they first harden. Hope this helps.Last edited by Daffy427; 11-07-2008 at 05:49 AM.
