I recently had a pretty good-sized hole in my bass boat. It may not look like it, but it went all the way through. I took my boat to Chris at Classic Fiberglass and he did an amazing job! Not only that, but he also fixed all the screws in my rub rail that have been giving me a fit backing out all the time, and he did that at no charge just because he noticed it was happening.
If you need fiberglass work done, there's no one else you should consider. Just ask someone. Chris has a solid reputation, but I wanted to share my experience to back that up!
Before and after shots attached. Not sure why the forum made the after shot upside down, but you get the point.
