Jon,
This must be heart breaking. I doubt very much if the problem lies with the
car paint - I have used the stuff on smokeboxes and boilers running at
110psi with zero lagging and never had a problem. Could it be that you have
used a primer or undercoat that has blistered underneath the car paint? Was
the metal absolutely clean (i.e. washed with cellulose thinners) before you
aplied any paint?
