I used it on my MH about 8 years ago and was pleased with the results.I would not use it on a newer MH that still has good gel coat shine it will flake off. It lasted about 3 years before it needed another application. The front cap area needed more applications due to the bugs being cleaned off. I never did strip the old stuff off I just recoated it and it blended in well. It will wear off by itself after repeated washing's. Some from Az or other sunny areas of the country have reported yellowing, I never saw any being from CT.
