PPG recommend DP40 as a substrate for polyester fillers (bondo). It's
been over 2 years now, and no problems. For the record, bondo will not
stick to Vari-Prime, so don't try that. It peels right off. I do not
want to worry anyone who has used Vari-Prime, however. I have no reason
to doubt that it is a fine product when used per directions. I sure as
heck wouldn't strip a Healey chassis to get rid of it. Dupont never said
you should put bondo on Vari-Prime; I just got carried away.
