has anyone used ppg dplf epoxy primer on a bare metal frame? how does it work and is it easy to sand and weld around?

[unbearable]

you'd be better off with SPI ,,,

Forget DPLF, over priced and under performance. PPG epoxy primer has not been worth a flip since they did away with the lead formula. I agree with the SPI epoxy primer suggestions, it is far superior to DPLF and half the cost.

PPG does have a epoxy primer that is self leveling but not for the ch#@p budget type. Be sure and clean up any equipment right away cause it isn't coming off after it cures..

For those interested ...NCP -280 needing NCX- 285...
2 parts primer to 1 part hardener , than a capfull of acetone per ounce to adjust flow through the gun...

Self leveling works best with wet on wet coats ..



Wow , I'm not alone... http://www.sporttruck.com/techarticl...preparing.html

"03. Now the fenders are coated in PPG's NCP 280 high-build surfacer. This stuff must be mixed with NCX 285 catalyst so it will dry. The 280 primer self-levels, which means it seeks out low areas to provide the smoothest surface possible and in turn cut down the sanding time. Three wet coats were laid down in about eight-minute intervals "

Self leveling ...

self centered?

I agree stay away from the DPLF. i used to use it all the time before it went LF.. but it's not the same.

Milo, NCP is NOT an epoxy. It is an "ISO free" primer similar to a urethane but NOT an epoxy.

It is damn good primer, high filling, direct to metal and one of my biggest road blocks when I was selling against it.

I'm sorry Milo, I don't understand what you just posted. NCP is an iso free filler primer. Does it say somewhere in it's literature that it is an epoxy?

Milo, I think the PPG site has messed you up. I just went there and clicked on the P-Sheet for NCP270 and got the DPLF tech sheet!

I went and googled it and came up with this..http://72.14.253.104/search?q=cache:...s&ct=clnk&cd=4

Calling it an epoxy would benifit them, epoxy "primer/sealers" can be 3.5 VOC while a filling primer has a 2.1 limit.

Honestly, you may have someone calling it an epoxy SO they can sell it to you being it does meet the 3.5 VOC when mixed 3:1. But it is NOT an epoxy as far as anything I have ever read on it.

Then it's better than an epoxy... Primer Sealer ??

[MARTINSR]

I have no idea why you posted that link, it doesn't say a thing about NCP. You are on the west coast, it isn't that late right now you can't be sleep deprived.

No, but I was just told that the MSDS on the NCP calls it an "epoxy hyrid". So I stand corrected. I do know that it certianly doesn't sand like an epoxy, it is a nice surfacing primer.

Oh, and it sure looks like that is not a compliant product here in the bay area. You better be using it along side your neighbors meth lab so you can watch each others backs.

I saw in that link that epoxy is different things when not in California... About 15 years ago I asked my paint jobber for a epoxy primer that I could depend on not to mess /react with laquers or enamels and something the guy with the BAAQMD clipboard wouldn't hassle me for...He slid some NCP 280 with some 285 hardner/catalyst across the counter with it , called it (shhhhh) epoxy and I haven't had a problem since... To me an epoxy is two parts when mixed together get hard and when it cures it doesn't change what it touches...

For a second there I was thinking I was hood winked as well...
