Which primer?

[meatloaf]

With what I have read here... I can go with an epoxy primer for bare metal & paint combinations, correct? DP90 seems the way to go? My son used some home depot paint stripper to remove the paint from my truck and I am debating to go ahead and strip the whole (exterior) truck to bare metal or just sand the remaining.

Thanks for all of the info,

If you use a cheemical stripper you must was the rig off before applying a primer. Dp90 is what you need to use.

I thought I read somewhere that they discontinued DP90?

Mine is freshly back from blaster and humidity levels at 90%!

Just a note: the DP line comes in different colors. DP90LF is just the black version of it. DP50LF is grey.

I believe that the original DP90 is discontinued, replaced by DP90LF (lead free).

I could be totally wrong on that though. I use DP90LF/DP50LF. I love the stuff!

hey fellas. fwiw, since dp went lead free, i've witnessed it peel from bare metal. i'm a collision & frame tech for a local gm dealership & i've also did my time w/classic restorations so i've been able to try about every product out there. this is only an opinion, but southern polyurethanes makes a much better project & it's about half as much per gallon kit.

Any other thoughts on the LF version of the DP series? DP90 used to be the standard, but I've heard a couple comments similar to Max's about the lead free version not being "all that" anymore.

Also, as DanS mentioned, the DP series comes in a bunch of different colors. Everyone always seems to refer to "DP90" but I actually see a lot of what is being used is the DP40 - the grey-green stuff. Some of it comes down to top-coat color, but any other advantages of using a certain color of primer?

For reference:

• DP40 - grey-green
• DP48 - white
• DP50 - light grey
• DP60 - blue
• DP74 - red
• DP90 - black

I used to use the old DP90 back years ago and it work real well.
Then when money got tight I started looking for something a little less expensive..."not cheap"....there is a difference.
I started using the Kirker epoxy Enduro Prime. I really like it.
It seems to stick good, sprays good and if you do mess up and need to sand it, it doesn't ball up in the paper like most other epoxy.
Works good for a sealer coat just before painting too.
I have used it to paint some of the '80s monster aluminum bumpers and after 5 years....no sign of any problems.
