auto paint and aluminum

Aluminum is finicky and will shed paint of most any kind after awhile, like on airplanes, even they are subject to wear. Ford painted the hood and tailgate on the Expedition and Excursion models and they were aluminum. Mine is 6 years old and there are some corrosion pops on it. Mercedes paints the SL models and has for 40 years (aluminum deck lid) SL was to stand for super light. The proper auto paint will stick to aluminum, if applied correctly, but like airstreams plastikote covering it needs attention. I cleared the faded gelcoat stripe with automotive paint on my SeaRay boat and it looks good today, prep and application technique is paramount.

Nothing is forever except for taxes.

Ok Andy what type of clearcoat do we need? Is it only available from Airstream at $XXXX per ounce like French Perfume?

Your free to do whatever you wish to do with your Airstream, but I promise you, that your time will be wasted fooling around with a clearcoat that's 40 years old.

The Thermosan was a black water wasted disposal system designed by Thetford, that just didn't work out. A connection was made from the trailer to the tow vehicle to carry the black water to the tow vehicles exhaust system. It was supposed to pump into the exhaust system, as I recall after 25 mph and faster. That, indeed, did work.

BUT, the system also worked at a stop light, which needless to say, plugged up the exhaust system and made a mess on the street.

Needless to say, that created a health hazard, and the system was quickly abandoned.

Imagine taking a car to an auto dealer to have the exhaust system cleaned out because of the black water deposits.

I'm sure you get the idea, loud and clear.

Andy

Here is a daylight shot of the after on the faded white out effect on the crown, DIY only $20. Did it because of the metal scarring PO did.

Plastikote 2505

I found that Valspar makes a product called Plaistikote in an Enamel form. Had anyone got any experience with this product?

Thanks!

Why not try auto clear coat if Airstream plasticoat only lasts 5 years?

I would be surprised if auto clear only lasted 5 years, and more surprised if you couldn't find a local shop that would spray a trailer for much cheaper than taking it to be recoated by and Airstream specialist. Eitherway you wouldn't have anything to loose if both products only last 5 years.

If you stripped the trailer yourself and preped for paint you would only have to pay the materials and spray time costs. Automotive clear isn't cheap but the travel cost alone could save you a bundle.

Also, you can blend auto paint, or paint only one panel if there is damage, so there's no reason you can't have only part of a trailer re-coated if the rest of the coating is intact (not peeling)

By the way, I paid my way through Unversity working in an autobody shop.

I have no experience with painting vehicles, but I'm the skeptical type. I wonder if auto clearcoats are formulated to need the primer and color coats to bond to, rather than bare aluminum?

It has seemed odd to me that just a few places redo Airstream clearcoat (P&S comes to mind) and I wonder if that's the reason. For the moment I don't have to wonder TOO much, since mine takes paint instead (and could sure use some!)

(edit) and DUH, I see a few posts above that andy is saying essentially the same thing.

Auto clear coat is designed to adhere to paint, not aluminum.

If it's applied to an Airstream, after a couple of months or so, it can be peeled off like cellophane.

Granted, the auto clear is far superior than the Plasticote, but it's purpose and useage is very different.

Today's after market plasticote from Airstream, is a 2 part mixture.

It's available from a few dealers who stock parts.

What about surface prep. Most coatings over aluminum require something like Alodine to etch and seal the surface prior to clear coating. I suppose that AS might have some special formula that is self etching.

Whatever they use and however they use it it's not working, paint or whatever should last more than 5 years on the roof of a trailer.

Just start polishing and get it overwith! If I'm going to have to spend money and effort to maintain my finish I'm going to have the most shine I can

As a side note, I coated the aluminum wheels on my '83 Mustang in 2004 with automotive clear with a flexiblizer added, those wheels look just as good today as the day I sprayed them.
