Protect All or 303 Aerospace

[tmmar]

Going to put something on my fiberglass roof to protect it. Which will last longer- Protect All or 303? Also, which will do a better job of protecting the roof?
Thanks

I use Protect All on my airplane and on my last MH. Bugs come off easy especially when they hit you at 200 mph. Going to use it on my new MH next week. The airplane is 17 years old and still looks great.

Using it on your shower skylight is a great idea! Wish I had thought of it. My skylight cracked due to UV damage!

Protect All can actually damage some materials, so check that product carefully.
I've been using 303 for well over 10 years and my boat got sprayed from vinyl top down to trailer tires.
Makes very good water repellant on windshield.
Not recommended on paint, but my trailer paint was faded anyway, so I gave it there as well. Did not notice any ill effects in 5 years owning the boat, that was 12 YO when I sold it.
At the time 303 had only 1 formula, now they diversify.

In reviewing Protect All's web site, it appears it's mostly used for removing oxidation from fiberglass leaving a polished finish.

The 303 Aerospace Protectant touts a powerful UV blocker which seems to me would be a better choice to use on a fiberglass roof to help protect it from the sun's damaging UV rays.

I use the 303 on my coach tires and on the outside of our shower skylight.

Good luck with your choice & safe travels...
