Faded front cap restoration, what I did.

As some of you have seen in a prior topic of mine, our 250RS has the dreaded oxidized and faded front cap. The upper section had dry powdery gray oxidation all over while the lower half was still shiny but had patches that had just turned gray. I’ve tried various products to clean it up without success. After getting bids in the $3k range to strip the graphics, paint the cap and install new graphics, I decided that I needed another option. It didn’t have to be perfect. I just couldn’t stand how bad it looked.

Now that I’ve finished working on it, I thought I would share what I have done and the products I have tried to maybe help out some of you that are in the same situation. It doesn’t look new, but it looks a whole lot better than it did before.

All the products I will be mentioning came from Amazon. This isn't a commercial for Meguiar's. I have used their products for quite a while and decided to stick with them. For those of you not familiar with Meguiar’s products, the model number is Mxx followed by the ounces in the bottle. I started off trying Meguiar’s M6332 Flagship Premium Marine Wax. I’ve been using it on the sides and back of the trailer for years and have always gotten great results with it. Unfortunately, it would touch the oxidation on either the upper or lower sections.

Next, I bought a Meguiar's M4965 Marine/RV Fiberglass Restoration System along with their drill mounted “DA” G3500 Dual Action Power System Tool. The DA comes with a yellow pad for polish application. There are also red pads for oxidation removal and black pads for wax. The M4965 kit includes M4916 oxidation remover, M4516 polish and M5616 pure wax. Although the oxidation remover did take a little of the oxidation off when used with the DA and a red pad, it wasn’t nearly as much as I had hoped for.

I then had the bright idea to use my go to cleaner, a Mr. Clean magic eraser. That really took off the powdery stuff but didn’t do anything for the discolored shiny areas. The darker section is this picture was using the magic eraser.

Looking for advice, I called Meguiar’s and talked to one of their service people. He recommended M6732 Marine/RV One Step Compound. This stuff is supposed to have a more aggressive grit for removal of oxidation along with polish and something that helps restore the color. I tried using it on a section where I had already used the M49 (red pad) and M45 (yellow pad). It took off more oxidation and left the finish darker, more like the original color.

In the end, I went over then entire cap with the M67 (red pad) and M56 wax for added protection (black pad). See the image below.

For the LP gas cover, I decided to try a Cerakote Ceramic Trim Coat Kit. I’ve used their ceramic coating kit for headlights with great results and thought it was worth a try. I also applied the coating to the plastic cover on my Huskey Brute 4500 power tongue jack.

The final result.

As far as the sides and back go, since the trailer is almost ten years old, the graphics are starting to peel. To avoid damaging them more, I tried Meguiar’s M5916 Marine/RV Quik Wax Clean & Protect. It’s a spray on/wipe off product and added a nice shine to the trailer after a wash. Will just have to see how long it lasts.

That came out really good! Looks like a lot of work.
I put in more work than was needed, trying out various products. Next spring, I hope to use the one step compound followed by the wax and be done with it.
It looks fantastic! I have to say, the before/after pics are astonishing! Thanks for sharing the products and your approach.
Is your trailer covered or uncovered?
Uncovered in the Seattle rain.
Has that caused any issues with leaking? How often do you have to recaulk roof....plumbing vents, vent covers, front/back seams as well as all vertical caulking...windows, molding, etc?
No roof leak issues. I did have the silicone on one of the clearance lights at the top of the front cap peel back. Found it when the trim piece between interior panels over the upper bunk came loose at one end. When I went to put it back, I found rusty nails sticking out. Tacked the trim back on and used a little liquid nails to be sure it stayed there. Found the leak and fixed it. No problems since.

I check the roof and look it over every spring. None of the roof vents have needed recaulking. The only spots that have are the screws in the metal strips at the front and rear edges of the membrane and some of the antenna attach screws. Besides that, no roof repair except for where a tree branch tore the membrane. I always keep a repair patch in the trailer just in case I need it.
Sounds like it has held up very well. Good to know.

What roof repair kit do you carry? I should probably carry one myself. I have used Eternabond tape once when I replaced a cracked plastic roof dome that goes over shower. That EB tape sticks to no end!
This one. Cheap insurance to have on hand.

which product would you use if you were only going to use one?
For the front cap, I plan on using the M6732 Marine/RV One Step Compound from now on.
would one bottle be enough for the cap? 32 oz? you do it by hand or machine?
One bottle should be plenty. Of course that might depend on how bad your oxidation is. I applied mine using a Meguiar's DA drill attachment. I also bought the red compound pads to go with it. The only buffer I own doesn't have the power to scrub off the oxidation. The hardest part was reaching the top center of the cap on a ladder.
