Help with Frame Restoration

ok, try not to laugh
We are trying restore our 68 camaro. We need to know what are the steps after you sand blast the frame? Or if you know of any sites or links that would give a like a play-by-play. I've looked around and it seems like por15 is what we're going to use. I'm really lost when it comes to the phosphoric acid/etch/primer? Any comments would be great and thanks in advance.

Since you sand blasted the frame using por-15 wouldn't work. It needs rust to react with in order to stop the rust. If you could spray it inside the areas the blasting didn't get to then it could do its job though.
I just use a good paint for the frame.

I did my Galaxie many years ago (at least 10). I just cleaned up the frame and sprayed it with some $15 a gallon Western brand black enamel paint. It still looks good after all these years, surprisingly.

I am just curious is you are planning on taking the body off the frame on the unibody car you got there?

I use Tremclad rust paint on frames. Works good.

Chris I'm not real sure what you mean. It's a sub-frame. Is that what you wanna know? And we're taking it off the rest of the car.
I know this isn't a real complicated question, but I want to try do this right. Thanks for the por15 post, that will save us a bunch of money.
And poncho62 do you have to prime it first and do you spray it on or brush it.
Really guys, thanks alot. The car was bought for my husband to rebuild with my father, project car, but my father passed away. It's like a mission for me to get this right. I can't let something half *ss roll down the driveway or have our last name associated with it. He'll haunt me.
Thanks Again

An etching primer is used to help adhesion of the primer to the metal and the paint to the primer.
Since most project cars that go as far as a frame off don't see the worst of the elements for very long( if at all) I would feel safe just using a good basic paint. Krylon is a favorite of mine. I just like the sound of the name. Krylon!
But use what you like.

I'm no expert but this is how I did the chassis (frame ) of my F1
Pickup once I had it blast cleaned. I had 2 options, painting or Powder coating. Because I live in England, which is pretty damp most of the year and salt is used extensively to keep the roads clear of ice and frost, I needed a finish that would be durable and cope with being used as my daily drive in all weathers.
I would have loved to have had the frame powder coated but transport costs to the nearest powder coater capable of doing the work was pretty high, so I decided to paint the frame instead.

It first had a phosporic acid primer, then 2 coats of zinc rich primer
(the zinc content helps stop any future corrosion) followed by 2 coats of enamel chassis black (I believe Eastwoods in the States sells this) I sprayed this but it can be brushed on. The areas which were likely to get stone damaged were given a coat of stone chip guard and finally the whole lot was given a spray coat of underbody wax.

This will probably seem a total overkill by many people but it should last another 50 years, which is the important thing.

Hope this helps.
