Hi there,A little confused...see my siggy below for my coach... I bought some Meguiars Ultimate Liquid Wax the other day from Wally world, the most expensive Meguiars there was...was going to do a thorough job on the MH. Is this a good wax for my coach? Will it be ok on decals?My main concern is protect it. I see when I did searches...that many use Aerospace 303 on the whole coach...Should I just go that route? Seems easiest...THANKS.

Aerospace 303 is not a cleaner, not a polish, not a wax. It is a water based SPF40 UV blocker that washes off when it rains and that's all.

I use a wax called Nu Finish on the front of my coach and all the metal storage doors. I use 3 coats of wax to get me thru a season! I use Aerospace #303 Protectant on my fiberglass it's a "SPF-40" UV Protectant that is earth friendly and on the bottle it claims to be "The Worlds most effective UV screening product. I've researched Aerospace #303, and it was designed by a Boeing Airplane Engineer (Boeing uses it on all there Airplanes to maintain luster on there finishes),I also researched it when it first came to the market to find out what ingredients are in it and none were listed (not one)! I even (did a MSDS search) and not one ingredient was listed due to a Federal Law, that protects a persons product! If it was petroleum based (like Turtle Wax tire products) it would have to be listed according to Federal Law. On the bottle that I have it say's for RV use that it can be used on Fiberglass, all interior/exterior vinyl and leather and can be used on RV EPDM Rubber Roofing. It says for maximum protection use every 3 to 5 weeks. My coats of #303 last about 2 months here in the rainy Pacific Northwest then it starts to loose it's luster. On fiberglass and decals, I've used everything and what works best for me is #303 or Pledge Furniture Wax both really easy to work with. Good Luck, Rooster

I have never used wax! The only thing on the coaches has been Rejex. It's an aircraft polymer that repeals everything. I do the coach about every 18 months.

And neither Meguiars Ultimate Liquid Wax or Nu Finish are waxes! Ultimate Liquid is a synthetic "wax" and Nu Finish is described as a polish, but I believe it is also a synthetic product. There are very few true wax products on the market.

Again 303 will wash off in rain. I prefer to Rejex the whole thing.

But best read the instructions first for Rejex, as it is not easy to properly apply. -
"REJEX APPLICATION
Ideally, RejeX should be applied to a cool, dry, clean surface. When over 85° F, be sure to apply RejeX out of direct sunlight. If the surface is too hot, the coating can cure before it has properly bonded to the surface, so it may not perform up to its potential.

RejeX is wiped on, allowed to dry to a haze for approximately 20 minutes, wiped off, then allowed to cure for 8-12 hours (depending on the humidity; the higher the humidity, the faster the cure). Curing is required to allow the monomers (polymer building blocks) that make up RejeX to attach to the surface being treated and to crosslink into a crystal-clear, impervious film. It is important to allow RejeX to cure for 8-12 hours after the haze has been wiped off. If the coating is exposed to contaminants such as oil, fuel, soot, hard water, tree sap, cleaners, etc. before it has cured, the contaminants may interfere with or imbed in the protective film."

I think I will stick with NuFinish. I can apply in the sun, which there is a lot of in the Nevada desert, and I don't need any humidity for it to cure, which there is not much of. Simply wipe on and then wipe off just like the Karate Kid.:b
