I dropped into Rib-Shop today at Eastlands Boat Yard on The Hamble http://www.rib-shop.co.uk/
and again great service- Keiron has given me a new cleaning product for the Tubes which will be sold as Tube Shine, He asked me to test it out as we wash and clean boats regularly. I was looking for a spray solution to finish off the tubes and seats and then just wipe over.
So far it does what Keiron hoped and is very effective. I will keep trying it in the coming month. The images are not that clear but the bow area of the tubes has been treated and the one image with blue tube below rubbing strake has not. I think you can see the difference on the finish in photos
I am sure Keiron will correct me if I have this wrong and may be able to say what it should be able to do
