markvt, I made the same comment when we took delivery of our 21. I plan on finishing the paint job also. Pete

Is this just regular construction grade foam? If so it needs to be protected by an Elastomeric paint. Any light will degrade construction foam over time.
I am not sure how long ETI has offered the spay on foam option. But you do bring up what I think is a very good point about UV damage to foam exposed to sun light. I have worked many years in the construction field and know that it only takes a couple days for foam insulation sheets exposed to sun light before they start to lose there R values. If you are building a house and are using foam on the exterior you need to cover it ASAP to protect it from UV damage.

An inch to an inch and a half would raise the floor significantly and would be difficult to install evenly and would not cover the tanks underneath. The option was there when I started looking three years ago. It appears to be regular construction grade foam which begins to turn a much darker yellow over time.

Hi Pete,
I have to say that now that the job is finished I am really happy with the out come. It was not fun crawling around under the trailer. Just make sure you use a drop cloth on the ground under the trailer because your going to get paint dripping down off the foam onto the ground.
Mark

I wonder if something like Line-X could be sprayed over that foam. I'm having our pickup box sprayed in a couple of weeks and that stuff is pretty tough. Loren

Yes, it's tough, but I doubt that it's flexible enough, and will end up cracked. I'm not so impressed by coatings such as Line-X: they work fine in truck boxes, but where I've seen them used as an exterior coating (such as on a welding truck body), it seems to crack, peel, and just generally not hold up.

I'd be careful not to use any solvent based paint or coating over the foam. It could damage it. Probably best to stick with a water based elastomeric or latex.

Has anyone asked what ETI uses? I just had mine done and it took a while for the paint to dry. Smelled and was tacky like a solvent based spray paint. I would think that additional painting should match ETI 'a since no one who has had the foam for three years has reported a problem.

Good point. It would have to be compatible with the chemical composition of the foam. Some paints or solvents could actually dissolve the foam. Best to find out what they use at the factory and go with that or a like product.
