- Do you want protection after restoration? Some products include long-lasting sealants or polymers to protect against UV and water, reducing future maintenance.
- What type of boat surfaces do you have? Gelcoat, fiberglass, and plastics can react differently. Choose a product formulated for gelcoat and fiberglass for best results.
- Ease of use and time required Consider whether you prefer a one-step solution or a kit that requires multiple steps and cure times.
