Well i finally decided to attempt to get rid of the antifoul..
First i tried the "Dilunett antifoul remover" , this was absolute crap tests after 1 / 2 / 4 hrs only partially removed the first coat and didn't touch the undercoat ..... 2.5lt = £26.00 ..
Next on the list was "International Interstrip" 2.5lt = £37.95 , this works "VERY" well, one coat and straight back to the gellcoat, although has to be scraped off (jetwash just seems to move it around) then a final wipe with a 50 : 50 mix of Acetone / petrol its as good as new
Now for the other side
