Anyone used spray on insulation?

We're pondering ... the home improvement guy was here at the house measuring for a new window and was fascinated by my little Forester. So I showed him the inside and he suggested we use that spray on foam insulation that hardens.

Has anyone used this? He said it goes on about 1/4" to 1/2" thick, hardens and would also prevent any water damage since water couldn't get in past the insulation.

Naturally this intrigued me ... I've seen/touched it in basements and was wondering what the opinion was on campers.

Anyone?

Nope, wouldn't do it. You can never get it all off if repairs are needed and it doesn't prevent water damage. Yes, on what it sticks to, but there are nooks and crannies that will allow water in. IMO, it is tacky.

Thank Vikx ... we're gonna just go with the R-4 rigid insulation.

I know VK already answered, but couldn't help myself and am sharing this for a later reader who comes along and isn't convinced. The attached is one of the many pictures of spray foam insulations surrounded by dry rot from the back of my trailer (it was in the front too!) It is an absolute mess to take off the aluminum skin too! I softened it with acetone and then used the rigid scraper on my dremel multi tool, and then more acetone and then.....you get the picture.
