I am starting with 100 grit to get the old paint off, then 220 grit to smooth it all out before painting. I have a 320 grit wetsand which is very smooth to use in between coats, but I didn't know if this was necessary or does the paint turn out perfect without sanding in between.
Here is a picture after the 100 grit, it takes a long time to get in the crevices!!
