Oh it will do the trick, it's fantastic. It's a coating not a treatment, that's for sure.

I just noticed this week (after 4 months) that I had a few small areas where the R/R appears to be kind of scratched off (from brush or branch maybe?), so I'd recommend putting a heavier 2nd coat and maybe a 3rd coat on. It may be because I used a microfiber rag to apply it with, as I didn't have ANY residual to wipe off as instructions described.

I'm going to try to do the entire cladding again soon. There's PLENTY left in the can to do it over.
