Alkaline immersion dip and undercoating
I posted this also on my frame off thread but thought it would be worthy of it's own discussion.
I talked to a guy at Redi-Strip. They do not do a acid dip. Acid dips create all the trouble will seepage and finish failure on frames where you get the seepage. They do a alkaline immersion. I read a lot about it on other forums, one in particular was Hotrodders.com. You get the entire frame inside and out cleaned and it has a rust preventive coating on it. When your ready you rinse that off with water and top coat it. I guess I will use POR-15 or the Eastwood product. They say any seepage that you don't thoroughly dry out is no more harmful than water and if your top coat is dry it will have no effect.
They say they have done many Vette frames and cost is $500- $800 depending on rust but probably more close to the $500.
So I am looking for comments on this, and what to coat the inside of the boxes with. Eastwood has a undercoating system you can do yourself. Or simply a boiled linseed oil which is what they use on steel tube airframes. Or powder coating which will go inside and out, I guess?
Any thoughts?

Scott,
The link didn't work. But I guess I need to do a little more searching myself.

There are a number of things you can spray inside the frame. The Eastwood waxy coating is one. Chain saw oil is another. It is very sticky because it has paraffin in it. Chain saw oil would probably need to be applied every couple of years to be safe. Used motor oil is a very inexpensive alternative - an old New England rust treatment. It would have to be applied yearly but you can't beat the price.
