I was wondering if anyone could tell me what they use to wet sand and buff acrylic enamel. It is Dupont Centari with 793S hardner. I have heard that 3m-perfect-it products are good, but there are so many to choose from that I have no idea where to even start. Reason I need to sand and buff is that I have a few dirt specs in the paint. I painted last night and I am also wondering how long that I should wait before doing this.
