roof coating

[patp]

last year I coated my rubber roof with an elastomertic paint from Brentwood Roof Coatings in Canada.The roof had no cuts or leaks it just had some black spots showing so I decided to spruce it up. I purchased amount recommended and applied as per instructions. In the spring of following year (4 months later) I noticed the roof bubbling in a couple of spots and found water accumulating under the paint.Later in the year I notice patches peeling off and after several conversations with manufacturer I was told it was my fault and they would do nothing for me as I was the only one in over 1000 applications that failed. Also had to have the entire roof replaced as water was trapped under the paint and got through to the wood underneath, this was all due according to rv tech because this product will never adhere to a rubber roof that is more that 2 years old.
He said he has seen quite a few rvs with same problem because the paint is applied to a roof that is more than a couple of years old , my Montana was 2005. Has anyone else had this happen and what recourse did you have?
