I've had excellent results with PPG DPHS52 Epoxy Primer Surfacer. Not
cheap, but builds and sands very well. I would stick with either WLS or some
other high quality epoxy primer surfacer. If you take a Dixie cup full of
urethane primer surfacer, it only hardens on the top. DPHS52 will turn
into a solid block.

What is the latest thinking on primer systems? Is WLS still the
preferred solution?
I've seen a lot of discussions in the archive on PPG DP40 and
even marine primer solutions.
