In reading this forum nurmerous people have indicated that PPG's DPLF epoxy primer doesn't have the same qualities (adhesion for one) that the old DP epoxy had. Can someone that has used PPG and SPI products tell me how the qualities of SPI epoxy compare to both of PPG's epoxies.

I have used both. I first primed my frame with DP PPG red, followed by a black coat of DuPont Imron. Months later while working on my car I removed some masking tape from the frame that I had on it to indicate the front wheels centerline. To my utter dissapointment when I pulled it up so did the DP and the Imron, down to bare metal. The frame was new and very clean, had been gone over completely with a tiger disc, wiped several times with PPG DX330 until the cloths were clean.

I have since use some SPI epoxy primer and it seems to grab much better than the DP, and it is a whole bunch cheaper.
