Wanting to hear voices of experience when it comes to exterior surface treatment. There's always good ole wax - like carnauba. I had a body man tell me once that wax builds up and yellows, particularly on new gelcoat surfaces. Has anyone tried Aerospace 303 Sealant (not the Protectant for vinyl)

. I've heard some good reports on it. So, anyway, whadyallthink?

I use 303 on the Diamond Shield and Wash Wax All on the paint. I did do all the bay doors with NuFinish and will try to do the rest of the coach in stages so the coach gets waxed annually.

Retired CW4 here, assume your name reflects rank?

I am now a hige fan of the new (ceramic) products. McGuires Advanced is super easy to apply and remove, leaves no white streaks on black plastic trim, and leaves a long lasting smooth finish.

As for wax build, once you wax it the first time I don’t think you will be in a hurry to wax again so no problems putting to much wax on it.LOL

I think any decent automotive or marine "polish" will work fine, especially since most fiberglass coaches are either painted (full body pint) or sealed with clear coat (and thus "painted"). I have my favorite brands, but so do others. Just about all of them are synthetic these days.

Pure carnuba wax is extremely durable but really arduous to apply and buff out. I don't think it has enough extra benefit to be worth the effort, but its your rV.

We have been using Nufinish for years on the coach and all our other vehicles. It's a polymer, easy on and easy off. Protects finish for a year and always looks great. Also removes oxidation on older vehicles that haven't been waxed for a long time.

Same as above post....

Our coach is stored under cover (no direct sun light). NuFinish pretty much lasts a year. Although I try to "wax" it twice a year. Wash it every outing, 6-8 times a year pre Covid.

Applies easily, is relatively inexpensive. I use 2 tubs per application on a 36' coach. Buy at Walmart.

Best thing is it makes bug removal very easy on the front of coach.

We use Rejex on ours. I just finished the annual job. We put it on the windshield and all glass as well. Seems to work as well as rainex on glass. It is liquid so easy on and wipe off. It does need 12 hours with no sun or rain to cure which makes it a timing issue, but it is well worth the effort.

When I washed it this spring it still beaded after a year. I do the high part and DW helps get the low part1, still a two day job.

Oil change and grease job already done, genny serviced, as is lubing all hinges and locks , so only thing left is to treat the rubber seals and wx stripping. Maybe later this week.

Interior wise, i just put the Wacko A/C silencer on the bedroom A/C big improvement, and switched a few more lights to led’s. Now just waiting for an opportunity to use the RV.

I use Meguiar's 21 Sealant on the coach body - 303 on tires and entire roof top including shrouds. Some folks are moving to the new ceramic coatings - waiting on reports of its ease of application and durability.

Aero Cosmetics Wash Wax All. Easy and lasts pretty good.

Another ReJex user. I just finished ours from front to back including the windshield. I checked with the makers of DiamondShield and they did not recommend it for their product but do recommend Meguairs Cleaner Wax. 303 Aerospace is for rubber products, not a painted surface.

I used to annually hand wax whatever RV we had and it took hours.

I stumbled across Meguiars Hybrid Ceramic spray on wax last summer and I've been converted.

Wash and rinse the RV. Spray on the Meguiars and hose it off. Yep, that's it.

Since I'm doing a 32' MH, I buy 2 or 3 bottles, shake them well and dump 'em into a pump up sprayer. Makes the application even easier.

It still beads up water now after being coated last October.
