A question that comes across every new tech's mind is what grit sand paper to use? Here is a guide to help you out!
Blends/panel blends:
Grey scuff dry/Grey scuff softened by water preferred to reduce the chance of sand scratch swelling.
1500 Grit/1200 Grit/ 1000 Grit/800 Grit, (be wary of paint burn)
Primer Sanding, (2k),
320 Dry, 400 wet , (every shop is different, ask for there guide on this one)
Black paint:
400 Grit/600 Grit/800 Grit
Dark paint covers scracthes very well
Metallic Colors/paint:
1000 Grit/1200 Grit/1500 Grit/Grey Scuff
Very easy to get sand scratch, be careful and be smart
White Paint:
Same as the Black
Single stage paint:
400 grit
Acrylic Enamel:
400 grit
Prior to Prime:
320 Dry/Red Scuff
New Bumpers:
400 grit wet or dry or my favorite, grey scuff with soap/scuff soap
Feather Edging:
180 then 320 then 400
Buffing:
1200 Grit or Higher
Very rarely to do want to use anything lower! i.e. run off removal
and I will post more when time permits!
