303 protectant
 

Don't know if this product has already been discussed on this forum but it should be one of the products you never without while RVing. I have used this for years on my boat and now have found so many uses for it on the RV. This will protect the walls and endcaps so you don't have to worry about fading and cracking. Give it a try, little expensive, but you get what you pay for. Check out their website, 303.com.

I just bought a canoe and this was recommended for protecting the hull, I'll be checking it out.
