Well I have to agree with Chris P here, I painted my front sway bar on my car over a year ago and I had it on the ramp last week and it looks as it did when I painted it. The key with painting is preperation, preperation, preperation and lots of coats following the instructions. With Hammerite if it is overcoated at the wrong times etc... then it won't be at it's best but a few coats on a well prepared surface should be fine. Rally car/DeLorean I can't really see the comparison myself, the nearest I get to off road in the DMC if the gravel driveway. At the end of the day it is crucial to cover rust with somthing, so choose whatever you feel happy with, in my Triumph Spitfire restoration manual it actually recomends Hammerite for use on the undersides of the floor pan.
