I was wondering about VPA over epoxy. I thought might be better over roughed up glass ?Wow all the vettes I have done over the years, that looks bad.
Personally after heat gun and sanding I would do 2 coats epoxy and next day VPA due to strength.
Other option is VPA without epoxy but just not sure with matting showing as never tried that before.
Thanks BarryI have with rare exceptions always used it over the epoxy, if repairing a 62 vette damaged panel I usually apply direct.
When I grind out bonding strips I use 2 or 3 coats epoxy first, then VPA.
