Hi ash how your doing? never thought about the underseal but it's the first time have had the car on the ramp to see it underneath without being laid on me back! will get it off with a heat gun
some of the wiring would be complicated as I have a heated screen etc
wil lhave a look I made one for my 100E years ago so could do it again.
hows your race car doing? out again this year?
