Back when Dehler had a few folks stateside that did their best to support the brand (about 2005), I got a new set of TBS precut nonskid panels for my Dehler 36. Big DIY effort to get the old stuff off and new down, only to find that the wear patterns came back in a few more seasons. Not that it got slippery, but brown, rust stain looking color shows through the light gray surface. We race the boat, so the wear may be atypical, but still. . .
I've gotten information from TBS in France about a paint they recommend for resurfacing their material. It's a two part, flexible polyurethane with a polymer bead nonskid additive, but made by another French company, Map-Yachting. I'm trying to figure a way to get a kit of their paint into the US, as they have no distributor here. HazMat shipping may make it too crazy.
Any experience out there with similar paints that are US available?
