I just painted my car back in June with a pvc system that was about a year or so old with no problems with fisheyes I used 3/4 inch White Schedule 40 that is rated at 400psi with no problems

When I first put it in I made the mistake one night of setting up a patio heater inside the garage and after about 1/2 hour my son said whats that smell well low and behold I had put the heater right under the pvc air line and with 150psi in the line it swelled up from 3/4" to about 1 1/2" but never blew a hole in the pipe
The next day I just cut out the piece and put in another
That was the last time I brought the heater in
