For anyone that likes to polish their tubes ! Or rather their rubbing strake and want to have it like new I have found the perfect product.
Its called Extreme Nano tech Tyre Gel by Turtle wax and makes Rubbing Strake shine like its gloss painted. Certainly if your going to sell your boat its worth doing. I apply with a sponge. wait a while and its sparkling. Seems to last a little while in water as well. I use it on my car tyres as well and it lasts a few dunkings in the oggin.
I'm going to do some experimenting and see how this stuff does on tubes and I'll keep you posted.
