Q1: should the repair be one-sided?
Q2: should the damaged area be ground back to expose the underlying laminate and where there is a gap between the foam and the chine a filler material installed, using the process illustrated in the article linked below?

Q3: can chopped strand mat be used to repair the laminate?
Q4: should I use an $50 Harbor Freight angle grinder instead of an orbital sander to taper the laminate and gel goat at a 12:1 slope and reduce the time needed to make the repair?
ASIDE: I went to harbor freight and got frustrated because I couldn’t find a disc sander. I found “dual action” sander/polishers, and the angle grinders have that guard which limits how oblique an angle you can apply.
Give me tips or tricks or advice for making repairs.
Q5: what is a good fairing compound?
Q6: is use of new fiberglass necessary to make a repair?
