Waiting or the weather

I am not sure if this helps, but I was talking to our trailer mechanic about replacing the internal skin as well.

He was experimenting with material originally developed for kitchen cabinet use. He showed me several samples, they came in different colours as well as brushed and shiny aluminum look. I can't remember the brand, but they looked fantastic.

It saw this at CanAm, they were outfitting a 34' with it. Maybe if you call them they can point you in the right direction.

work in progress

This is a follow up on the Diamond Brite use.
Good news and Bad news.
I pulled the coating off the aluminum panels. NOTE: It was a problem getting all of the protective sheet off around the rivets. I had installed the panels with the coatings in place (a good idea) to protect from scuffing. It is just a problem to pull it off later.

At the companies (KBS) recommendation I used a small roller and good brush to apply the coating. It self levels very well.

Coating tends to sag, even with thin coats. Because of that I tried to use thin swipes with my roller, going back over a few times. Good results….But, this may be the cause of my major problem

The major problem appeared about half way thru the job. I saw some thin areas as I used a light to scan the work. When I went and re rolled the areas I immediately had a surface defect appear. I don't know what, and the Company Tech is working with me now. I will follow up here.

The end coating is tock hard and will be a problem to fix. Lets see the results.

Back in early November I swapped some emails with the tech people at Diamond Brite. I was considering their clear product to repair the failing clear coat on my Excella. They advise me that I would not be happy with the results if I rolled or brushed it on. They told me that unless I was set up to spray, the surface would sag, run, and have an uneven appearance. I backed away from that.

I will be experimenting with the clear coat in a rattle can sold by Airstream. When I get started, I will start a new thread documenting my progress. I hope to get started early next year. This is a link to the product I am using;
Clear Acrylic Spray 28174W [28174W] - $17.95 : Out-of-Doors Mart!, More Airstream Parts on-line than anyone!

I do not know if the dealer hoisted the Bravo Sierra flags today or not, but he said the new (last several years) trailers aluminum skin has a corrosion inhibitor blended into the metal as it is made. The problem areas are the knife edges of the "skin" where the cuts are made for the end of a piece and all the appropriate openings. He suggested using "orange pledge" monthly as a way to inhibit corrosion for these areas rubbing the wax toward the joint or edge to build up some protection on the knife edge of the metal.

Some BS. "Corrosion inhibitor" is a fancy name for the factory clear-coat. Not blended into the metal, though, just a coating.

If it really was "blended into the metal," that would make it a new metal alloy. The inhibitor would be all through the metal, and a cut edge would make no difference at all.

Look at it like this: A cut edge on chrome plated steel will rust. A cut edge on stainless steel, which has chromium blended in, will not. Same principle.

A good corrosion Inhibitor has been around for decades, it's called "ALCLAD" to bad Airstream won't go back to their own history books and see what works.

Well, the warm spring is upon us, and I better get this project on the way before the heat of summer has me cooking in my aluminum tent.

Melody Ranch--anything to share as a followup to your Diamond Brite trial?

I tried the rattle cans that Airstream sales for touch up, those I mentioned in post #20. I'm not to happy with the results. The finish does not have the gloss or texture of the original finish. Prepping the aluminum where oxidation had occurred to match those areas that had no oxidation was a problem. I never figured out a procedure that would work. I think the only real solution is to polish the metal to a high gloss, which I do not want. Or, replace the metal panels, which on an older trailer does not make since financially.

I am told that the interior skins that Airstream uses in the CCD version are rendered low maintenance by the fact that they have a factory clear-coat plastic adhered to them. Question is: does anyone know how to get hold of this material?
To my knowledge, you cannot purchase that material, since it's applied to the metal before Airstream ever receives it.

All you can do, is use the 2 part mixture that Airstream has available, BUT, it is NOT THE SAME as the interior or exterior finish.

In the original post, I was looking to buy the aluminum, not just the coating, which I was aware was some kind of plastic film, not just a spray one clear coat. I found a dealer that could get me the coated aluminum, but it was freakishly expensive, so started entertaining other spray-on or paint-on options. I need to make up my mind which way to go pretty soon, as I need to get some insulation in my walls before the heat of summer gets here... It doesn't sound like anyone is discovering any "silver bullet" so to speak, so it might just be time to clean up my vinyl coated original skins and pop them back into place.
