I need some clarification on applying filler over SPI epoxy. I‘m only able to work on my projects typically every other month because we don‘t live full time where I have my vehicles.
I understand I have a 7 day window to apply filler over the epoxy without sanding or scuffing. However, I’m confused after reading some other posts regarding when filler can be applied over older SPI epoxy even after its been sanded.
I sprayed my last coat of Epoxy back in May. I’m once again block sanding the panels and have found additional low spots that need small amounts of filler. Can I apply filler directly over the epoxy which is freshly sanded? Or do I really have to shoot another fresh coat of epoxy before I can proceed? It’s so difficult and time consuming for me to get setup again to paint...
Another question. What will happen if I already applied filler (last year) over sanded epoxy that had been sprayed several months before? It’s now sandwiched in between the last coat of epoxy... Will it fail?
