Has anyone used 411 vs wax on fiberglass? If so does it work We'll? I recently got "new" 1977 13 foot scamp....needs some fixing up.
She just got a "butt lift" and much needed wheel hub even broke off in shop...luckily not on road. Wrong bearings on one side!! So thankful I had it checked...now it's road worthy. Now for stopping leaks and ... and... and!!

Endless discussions on polishing these trailers. There are basically two camps: Poliglow and Zep floor polish.

Third camp is regular marine fiberglass wax (along with various prep products) from Meguiar’s or 3M. I used the Meguiar’s Marine Fiberglass Restoration Kit to bring back a shine on my moderately weathered used Scamp. I followed with Meguiar’s Flagship Premium Marine Wax for ongoing semi-annual exterior maintenance. It produces a moderate satin sheen on weathered fiberglass.

Zep is currently the most popular alternative to regular fiberglass wax. With multiple (4-6) coats it produces a high gloss sheen even on older units. Fairly inexpensive at big box stores. You’ll need the stripper, too. Anecdotal reports are it lasts longer than fiberglass wax. It can peel if not thoroughly prepped.

Reviews for F11 did not look promising, and it seems to fall into the category of “miracle” products that promise perfection with no work. Silicone-based according to one review, which can leave unwanted and hard-to-remove residue on fiberglass. Fiberglass was not mentioned among the compatible surfaces. I’m skeptical.

Thank you both so much for the info. I most certainly don't want to make problem worse. I appreciate knowing before doing!
