Yes I did 50/50 concentration, and scrubbed it into the tubes. Left for about 10 minutes, then power washed it off. The power washer was a god send - did most of the elbow grease.
This was before and after.
EDIT - you can see in the pic the missing rubber - any ideas what this is referred to and where I can get some from??
Watercraft were originally built by Mr Wilkes ( I beleve was Tim wWlkes father)who then went on to build Ribtecs. They are tough Workboats and were built in Gosport and it very probably was a North Sea FRC.
tough stains try some 400 grit wet and dry avoid painting it it's a quick but very temporary fix. Ive had some ocasions to fix these tubes when they have had chunks taken out of them, I never really vracked the solution but I do know hypalon, two pack boyancy foam doesn't work.
we used to rent one in from mckay marine in Aberdeen and they had stuff that could fix the covering try calling them and asking if they can sell you reccomend stuuff
Thanks for the info. I also want to paint the metal work black. i.e the metal framework towards the stern. In places the paint has chipped leaving bare aluminium. Im a little dubious about painting over ally (regardless of how small the bare ally areas are) and was therefore considering power coating. But then I need to remove the electrics from the tubing...dont fancy doing that either.
The metalwork bolts are easy enough to undo, however im not an electrician (far from it) especially boat electrics. The paint has also flaked etc, esp. where the self righting gear used to be. So I will need to sand down also, leaving even more bare ally.
