Which wet and dry?

[R1XPH]

I have a tub of upol filler and am going to be repairing some chips and bits on my project car.

What grit papers am i going to need for prep, smoothing, all the way up to paint I was thinking 1200 and 600 or 800? but not sure what order etc.

filler you need to dry sand, you can wetsand it if you skim it very fine but it takes a while

for small chips/dents id use P180 dry, then go over that with P320 dry. primer it, then use P800, P1000 or P1200 to prep the primer

Perfect answer there^ no point going any harsher than 180 because you will just spend to much time removing the scatches that the paper has left. As said use it dry when its just filler. once you have a coat of primer on there you can wet sand.
