One of the local repair artists uses cellulose spray paint. Ordinary car-type stuff that you can get in any car spares shop, although I find that independents are better than chains. I was sceptical until he pointed out where it had been used on my boat on a repair that had been done before I bought it. I had never noticed in five years.

I had a few patches where the gel-coat was wearing thin and showing darker, also a couple where the "white" colour match was not too good. On a nice warm calm day, I put on about eight coats on the affected patches, athe the next day buffed them over with one of the farecla pastes. The result was great and lasted for about four years. It should have been redone this year, but never managed to get the warm calm day needed until the boat was back in the water. In fact I think Saturday was the first!
