Our hull is painted with AWLGrip paint over black gel coat. The color is a mix of AWLGrip dark green and black and you can only see the green if it’s in direct sun light. Over the last 5 years in Mexico the hull had developed a grey smear on it from the hard water, particularly in Ensenada where they have the most brackish dock water we have ever seen. You might as well be washing your boat with sea water. We’ve tried scrubbing the hull with no luck and were afraid that the only solution might be to have it repainted. You can’t wax the paint, the wax will turn yellow over time.
I started searching the internet for help and found a thread on the Cruisers Forum on AWLGrip paint and it was recommended to use AWLCare polish on the paint to seal and restore it. I ordered some, at $60 per quart, but when we used it it only seemed to make it worse. Smearing the grey rather than removing it. After that I contacted the AWLGrip rep in California and sent him some pictures of the hull. He suggested that we polish the hull first with 3M Perfect-It rubbing compound to remove the water spots and dirt and then apply the AWLCare to seal the paint. We hired a local young man in the marina, Luis, to do the job and the results were fantastic. It looks like new paint! Here’s some before and after pictures.

Hopefully from now on all we’ll need to do is apply the sealer every 6 months to keep it looking this good.
