A buddy of mine used to work in an autoshop and has good painting experience. I've got an old race fairing that I'm going to use until I get rear seat, etc. I'm going to sand it myself to get some practice, but my problem is he told me that I needed a flexible sanding block to sand with, and I can't find one anywhere. In theory I could use a sanding sponge, but I have to have 800,1000,1500 and the highest grit I could find was 320. Does anyone have any experience sanding, and if so, what do you use to sand round surfaces?
