I am going to do small scale sandblasting on misc parts of my tractor to remove old paint / mild rust. Some are cast iron some are steel, some are sheet metal. Settled on using Balck Beauty / Black Diamond but can't figure out what grit to use. Local store only has 20-40 and I am told that it may be "too aggressive " and I should use 30-60.
I typically use the MP170 Epoxy primer (2 coats) and topcoat of various manufacturers with hardener( 2-3 coats).
I am not sure what "too aggressive" means too me. Does it mean I will get poor coverage, and need to use more primer / paint... or does it mean that I will just be taking off more material then I should ....or...???
Thanks....Alan
