I glass beaded my dash to bare metal. I had to weld a bunch of holes shut that had been put in the dash over the years. If you look at the picture you can see some spots on the left side that were welded. I ground the welds down and was going to put some body putty in the bigger repaired hole areas. Then I was going to use a high build epoxy primer on the dash. What git sand paper should i use to sand the putty? and then what grit should I use to sand the epoxy primer.Any other advice would be apreciated
