New issue of Practical Boat Owner arrived today. It's always a good read, and on pg 62 - 63, there is an article on buffing out gel coat... on the author's E-38.
That caught me off guard!
If you find this at a chandler or nautical book store, the whole magazine is a good read, at least compared to the stuff in the main stream US mags. (IMHO)
