I don’t think I’ve ever dealt with a nicer bunch of people than the guys at Wave Wacker. If you need new knobs or new rubber down the road they’ll work with you to make sure you get em looking new again. They service their products for life. I’ve been more than happy with them.
I’ve also had good experiences with Walleye Masters. The guy is very nice and lives up here in the Alexandria area.
As for WhiteCaps I’ve never used em, but others here claim they’re great.
Splash guards are a great investment all around. They’re great to have and they’ll help you sell the boat someday as well.
