Because I tried a test. I had the metal four piece hood of my 34 primed with PPG DPLF epoxy primer. It had been primed for over three months sitting in my garage so you can't say it wasn't cured. After reading a thread in this forum about PPG DPLF wiping right off after cure with a lacquer thinner wet rag I tried it. Sure enough it came right off, I cleaned off all four pieces of my hood with a lacquer thinner soaked rag. I then primed it with SPI epoxy primer and let it cure for a week. Tried the same test as with the PPG epoxy. The SPI primer was unfazed, not even a mark. I challenge anyone who dis-believes this to try it and see. If you have never used SPI epoxy IMHO you have no right to challenge it. Use it and you will be convinced it is the best epoxy primer on the market.
