I am repainting my boat completely just dont like the colors. i know i need to sand , sand it , and sand some more.... but i sanded for a long time and only have a 6" sanded. this will take months!!!!!!!!!! I am using a 6" dual action orbital sander on a air compressor. Is there a better way ? what about chemicals ? if so what kind ? after sanding is finished what next ? Primer ?epoxy primer ? this is my first time doing this so any help would be greatly apreciated.... what kind of paint should i buy ? where do i get it ? i want to be able to perfectly match the seats i bought from ******** also.
