Rick decided to sandblast the truck himself, he's got a blaster and media and now the question is, what is the right type of primer? We want one that will prevent rust, the truck is probably going to spend the next few months before it gets painted. Sorry if this has been covered, it just gets a bit confusing, etching, epoxy, acrylic etc. etc. if the color the paint will be later matters the body and bed will be cream and the fenders/running boards chocolate brown.
Thanks guys.

Use some kind of Epoxy primer for sure. As far as color I'd use a white or grey since you will be using light colors. I think a light grey will be fine and that way you can also use a black guide coat to check for dents. Put about 2 or 3 coats of epoxy on and you will be set for storage for a while.
As far as which brand, that all depends on you and how much your willing to spend. If you want a nice paint job then use high end primers, paint, clears, etc. I'd go with SPI Epoxy primer...

IMO they make very good primers and clears and work with any basecoat paints available.
does it need bodywork?? the color wouldnt matter if you're going to be doing any bodywork on it, since it will be covered or removed anyway. the chances are very slim the you'll be spraying right over the epoxy that's on the bare metal. And you will only need one good coat, epoxy is expensive, so it doesnt pay to waste so much on it. just make sure that ALL the rust is gone, even if you see a little spec of surface rust, it cant be there if you dont want paint problems down the road!
Be careful with the sandblasting, or the type of primer you use won't matter. The metal will be so warped that it won't be worth painting. Has Rick ever done this before? Does he know what medium to use? It isn't as simple as it looks.

I'm taking the rust and old primer off my truck via sanding with a random orbital sander. There are a million little areas like little ding marks that still have spots of rust in them. Is an etch primer good enough or should I treat it with something?
There are some big areas like the rear fenders that were covered in rust. These I lightly ground down with a 3m pad , dusted the debrie off, washed off, then applied one step from mar-hyde which converts rust to black primer.
This process won't work fo the mostly bare metal with rust dots though. I'm looking for something I can apply and primer over the same day. Any ideas?
When I'm done it still will be 6months - year before the finish painting can happen. So on that note any primer that with prevent new rust? Thanks, Steve.
Any good Epoxy Primer/sealer will work fine. I would apply 2 or 3 coats at the most. A good source is http://www.kirkerautomotive.com/html/our_products.html

They have very good products and a very affordable price with very quick shipping.

I would use either metal prep before priming, or use a self etch primer, before the epoxy.
Rust starts on a microscopic level. (you can't see it) Make sure you include something to neutralize any rust, or run the risk of losing the entire paint job later.
Epoxy primer seems to be considered the most waterproof.
