I was told that I didnt mix it right or didnt apply it right., which was pure baloney. I removed all the PPG epoxy primer from my hood and replaced it with SPI which will not rub off with a lacquer thinner soaked rag. PPG paint is first rate but they really need to do some work on their epoxy primer because it is far from durable.
I just used my first SPI epoxy on the cowl and really liked it. The original DP was really good and I loved it but the DLPF is a completely different product.
