[NSRCA-discussion] paint

[Verne Koester]

The DP48LF is white but isn't a sandable primer. They're not  kidding about that. I used it a few years back and found that it sanded awful. The biggest problem is that the edges don't feather. I ended up sanding most of it off, re-priming with something else, and then feathering the new primer into the blotches of DP48LF left behind. OTOH, it makes a great gel-coat if you're molding up a part.

  PPG makes a white epoxy primer DP48LF hardners areDP401LF and the one that I use that is faster and allows the use of thinner #DP402 LF 
  See PPG DELTRON Bulliton #P-196 for technical details.for DPLF Epoxy Primer. This material comes in 6 colors Cost for the primer is about $40.00 per Quart, Hardner is about $20.00 a pint DTV Reduder can be used.
  Using PPG concept over a non fuel proof primer is a no no been there done that unless of course you are flying electric.
