Hi,
I have not heard of that product for RV's; they offer two products.
https://duckcoat.com/white-silicone-rv-roof-coating/ and
https://duckcoat.com/duck-coat-rv-15-year-white-elastomeric-roof-coating/Which exact product are you looking at? They offer both acrylic and high-solids silicone products, but both are very different.
And a heads up, they have elected not to include tech data on the RV coating products on their site; why? They have the SDSs as required by law, but there do not have tech data sheets for their RV coatings. See here:
https://duckcoat.com/resources/Does your roof leak now? What is your want/need by doing the coating? How long do you want the coating to last?
Trying to help, not challenge. I have experience with high-solids silicone RV coatings using Henry's 885/887 Tropi-cool and Crazy Seal brands. I have done 3 campers already and soon a 4th with these coatings. Each one there was learning from doing them. There is a learning curve pending what you are doing and trying to accomplish. I am just trying to help you avoid some of the pitfalls of marketing, not spelling out or needing to make the warranty work hiding in the fine print.
Let us know some of what and why you want to roof coat your camper, we can help better.
Hope this helps,
John
