I've been using a standard formula for all of my cars for over 20 years. {I used to sell used cars, and almost always had to paint them, or at least the top surfaces].

My standard formula is Nason 2k primer [not over bare metal, as I used the 2k with another Nason product for which I can't remember if the car was bare metal]. Then I used Nason single stage urethane to finish.

For my personal old vintage cars I would usually use the Nason 2k primer with Dupont Chroma Base top/clear coat.

However, money is tight, and I'm going to try to finish an old Ford project that has been sitting for years with the Nason single stage vs the Chromabase.

It looks like some surface rust is coming through the 2k primer I put on it years ago before the car sit [the car was stored in a garage, but here in the south east US, it gets really humid, which is almost like leaving the car sitting out in the weather.].

Anyway, I was thinking of trying Nason epoxy primer since I've heard it holds up better to rust, and better seals the surface [the car was stripped to bare metal before I primed it with the bare metal prep [Nason], and the 2K primer]. Also I had to put new quarter panels on the car, and cover the welds with plastic filler, so I don't want moisture to get under the filler.

Is there anything I need to know before hand to use the Nason epoxy primer? Can it be sanded? Can I just use the Nason single stage urethane with it? How long does it need to cure before paint, or should I just stick with the old 2k primer?

Thanks.

I would strip it back down to bare metal and start over with Epoxy or an Etch primer over bare metal.

:goodpost: i use the ful-poxy but have been useing the ----- for a wile now. the ful-poxy performed good for me, you shouldn't have any problems with it. its a little thin bodied so you need to be a little careful we you spray it. and yes you should take care of the rust, it will just keep coming back if you don't. you should look into Nasons Ful-base. i've used it several times and had good results and its priced right. the ful-poxy will need to dry a few days before it can be sanded easily. if you can, i like to shoot the epoxy then shoot some 2k primer over it a few hours later, no sanding of the epoxy needed. the 2k will sand much better and give you some filling also. you NEED to get the product info sheet with your epoxy and anything you get it will tell you when to recoat it ( 2k primer). the Nasons Ful-Thane ( s/s urathane) will go over the epoxy just fine, read the info sheet for cure times. the epoxy can be used as a sealer, also i believe the nasons 2k can to.
