I used some of the Mar-Hyde rubberized undercoating on some areas. I have let it sit for months now and it just does not want to fully set. It sticks to other panted surfaces.
For what its worth....

I used it on a Jeep several years ago and it held up great. I also used it on a motorcycle airbox and its still on there looking good, and it sits right on the engine getting cooked. It is also paintable over the top.
