Re: How do I fix bottom of boat
- Sand each scratch with 60 grit
- Apply gel coat (tinted to match color as close as possible) with a small paint brush (those metal-shaft chemical brushes work wonders) .. Apply as thin as possible while still filling scratches.. gel coat is tough to sand
- Sand smooth with 100grit, then 220, then wet sand with 320grit, then 400grit
- Buff with polishing compound
- Wax with carnuba wax
- Go boating
