Using 303 protectant on the roof of a 5th wheel

[jetlag]

A friend asked me about using 303 on the roof of our Pinnacles to protect them from UV rays. He found a YouTube video with a guy using it on his travel trailer. Does anyone have any insights in this? Can it harm the TPO roof? He has emailed the manufacturer and waiting on their response.

That’s what I use on my 2018 16Xrb. It has a TPO roof. I first clean the roof with Spic & Span, rinse it real real good, let it dry, than apply the Protectant 303. I also use 303 on my Tent ends, but use Dawn to wash them instead of Spic & Span. FYI a good medium stiff brush works good on the roof when scrubbing with the Spic & Span, to get the dirt, pollen, and mildew out of the textured roof.

BTW- I do it in the spring, and again before it goes to sleep for the winter.
