Kevin,
Restoring ’53 Chevy 1/2 ton pickup. Had to use some patch panels in usual places to address rust, e.g. Lower cab corners. Patch panels come coated in a black “EPM” coating. Not exactly sure what it is, but need to know what I must do to prep. Rest of cab has been blasted to bare metal and I intend to use high build polyester primer.
Thanks
.
