Etch Primer SUCKS? Use epoxy primer?

I have a 1980 El Camino and a 1971 Chevelle. These two projects take all of my time and most of my money. Sometimes I listen to the idiots at the parts and the paint stores and get really bad information. I hope someone can tell me what I can do to fix my latest headache. We sanded the entire 1980 El Camino down to bare metal and I let one of those previously mentioned idiots sell me some NASON 491-17 etch primer. I still need to fill some small dents with body filler. I bought Evercoat Rage filler. The Evercoat Rage is not sticking to the etch primer very well. Should we sand off all of the etch primer and then apply the body filler to the bare metal or should we spray an epoxy primer on to the bare metal and then apply the body filler to the epoxy primer? ( I will let you guess what I want to do the idiot who sold me the etch primer).

Although etching primer has its uses...It'll never work that way,I learnd that lesson 20yrs ago.It'll wash right off with laquer thinner and the bondo will pop right off with a putty knife.Resand the body with 80 or 180 da then epoxy prime,then resand that and bondo I use SPI Epoxy,its the best out there and well worth the wait if it has to be orderd if you have good b/w skills you wont need any other primer it sands GREAT and with a white guide coat you can get it nice and straight ,when reduced 20% it makes a fantastic sealer too....I use it at my shop on every car...

Clean off all that etch junk, sand with 80 grit and apply two wet coats of SPI epoxy primer, then do your body work. Follow that with some quality 2K primer/surfacer.

The only 2K I have any experience with is PPG K36, yea I know it's been out for ages but it worked good for me, and it is a little pricey. Had I known about SPI 2K pprimer at the time I would have gone with it.

I'd say around 200 is about right for high end primer from the big manufacturers (retail for sikkens 2+1 primer is around 250-300 for 6 sprayable quarts.)

The thing is, SPI ,IS a high end primer, even Better than most,so is their clear,but its priced so a working man can make a little money, Spi just isnt as greedy as the big guys, not yet any ways., But their hot line cant be beat, Every time I called I talked to Barry ,the owner. Mostly I just called with dumb questions but hes always VERY polite and friendly..That tips the scales in his favor.I'll never use anything else if I can get it from him.. Did I say I like the stuff ?

Picture a dog humping somebody's leg. That is just the beginning of his happiness with Barry's products and service.
