Sorry been off for a while...The only drawback i am seeing is i think effect of heat, slightly discoloring, the yellow around the pipes. I think its making the clear coat soft, and attracting the dirt. It needs compounding now and again. Not sure if there is high temp clear coat.
Its pretty labor intensive. once removed:
Clean thoroughly and apply adhesion promoter.
Then use a high build primer, then sand, build, sand etc until smooth - if you are happy with the current texture this step can be skipped.
Then base coat and clear coat. But, that's the one thing id take a look at - high temp clear coat...
Hope that helps
