Tuff coat advice needed!!!!!!!!!!

[ffr2608]

First post and new owner of a Zodiac Cherokee. The photos don't show it well but there is a large amount of burning on the topside of the tubes. Was wondering if you guys could give me ANY advice on Tuff Coat. Photos, long term experience, application etc....Would really appreciate any info as I am bummed about the surprises I'm finding on the boat. Was thinking of only painting the above the rub strake areas and leaving the wet areas alone.

Thanks,

Darrin
