First-class product!
Renovated a 45-year-old GRP sailboat. Hull sanded, but not all old paint and antifouling removed. The primer application and the resulting appearance are absolutely impressive. I'm thrilled!

I completely rebuilt my underwater hull using the Hempel system, and I'm very happy with the results. (5 coats of Hempel light primer (different colors), then 1 coat of underwater primer, and then 2 coats of antifouling!
