DP-40/401 or ?
15-20 years ago we were using dp-40/401 epoxy primer with great success. Is it still preferred and available? No, not a new boat, fixing up a current one.

I have never used it.

A comment that I'll add is that I've found automotive rattle can to work really well as a primer when doing small repairs. Over the years I've observed long cure time for both of the common flat enamel paints that folks use (FME and Parkers) when put over fresh epoxy. Hitting a repair with a little rustoleum automotive primer seems to lock in whatever causes the slow cure. I can also say that the priming ability and bond of the primer is excellent to epoxy under duck boat paint.

One thing that really stands out to me about DP is how tough it is. For example under the rear tie down strap it took years for the strap rubbing on the paint and then on the primer to wear through all the way through the DP primer. I repainted and went with a single pack primer to re-prime worn areas and it wore through in less than a year. I've yet to find anything that wears as well as DP. Not even close.

I don?t doubt it is the best primer. I?d rather rely on paint for durability and primer for adhesion. Having said that, flat oils adhere well to epoxy anyway.

I agree Eric. I've never seen anything like it either. My project is a 2ft x 7ft section of floor in my Lund that will see foot traffic of course.

Tod, thanks for your input.

After finding DP 40 on ebay for $135/qt kit it's on to look for regular auto primer. The primer shouldn't be the most expensive part of this project - sheeesh

We use the DP line of products in my autobody shop regularly. They are too slow for regular production/collision repairs but are the go to choice for restoration. It is an expensive product! We are fortunate to have the economy of scale when we use it and it's not that bad when you only need a few ounces and have it on the shelf to use.

Eric,
We purchase from Colours Inc., a PPG Platinum distributer. I believe they only service the north east. They have also recently changed to only selling to account holders, no walk in sales. Sorry that probably wasn't much help to you. Maybe someone in the north east can use the info though.
