I paid a guy to detail the RV 2 yrs ago and whatever he wiped on has left the fiberglas looking worse than ever.
I just did some research on this, and am going to try this
3M Marine Restorer for Fiberglass. It's a compound and wax in one application.
I just got this
Harbor Freight Polisher that's on sale, I plan to use this polisher with a foam pad to apply the 3M.
I'm probably 6 weeks out for some nice weather, but I like to have everything on hand so I'm ready to go when the sun comes out.
Honestly not a job I am looking forward to, but I was getting quotes of $700-800 to use a polisher instead of some magic wipe-on stuff, so I'll DIY ot and pocket the savings.
