I did yesterday, its going to come out well. It takes a little elbow greese and time but when its done it will be a DRASTIC improvement. I might go that route later after I get this oxidation off. Its actually almost black in some areas cause the previous owner never did anything. The home solutions took the scum line off, certain products but wouldnt touch the black.
Anyhow, I wanted to also mention this little gem I found the other day. I plan to spray but you can really get some good looking paint jobs for very little. I am not painting the boat, my trailer needs a little tlc on the wheel wells.
The $50 paint job....
