Wellcraft V-20 What to clean with

[BLU LUNCH]

Yesterday I was out looking to buy a replacement outboard for my trihull,and while I was in a shop talking my son saw a ad on the bulletin board for a 1974 Wellcraft V-20 CC no motor no trailer the ad stated that it had a brand new tramson professalny done last year at 1600.00. they wanted 1200.00 for the hull. I have a 3600 lbs trailer under my trihull it's overkill but I knew it would come in handy some day. The trihull is free for the taking. What I need to know is what is a good heavy duty cleaner for the gel coat and the inside that is not to harsh. The boat needs a good cleaning....
