here's a pick of a radiator that  supposedly came out of a 67 roadster that has had a new doghouse put on top, as well as been recored and had the bottom outlet moved from the left side to the right side.  this was done 2 or 3 months ago by a local radiator shop.  they couldn't do s*** for my gas tank though.

here's that radiator with a fan shroud (thanks John!)
i lucked out that both the top and bottom outlets clear the shroud, and all the bolt holes line up.

this gas tank started full of sand and rust.  when i got the truck (a 1971), they were "running" the the engine off of a 2 liter bottle proped up inside the bay... 
i dropped the tank and took it to where i had the radiator done.  a month goes by before they finally gave up on it.  no licensed welding shop would look at it (hahaha).  i ended up sending it to sometown, PA ([url=http://www.gas-tank.com,]http://www.gas-tank.com,[/url] i think)... and a couple weeks later (and a couple hundred dollars as well) this came back...  not very pretty, but supposedly no more rust issues... one of these days i'll swap it in...

Kinda pricey gas tank treatment.....Did they boil it out, or what?

Looks like they slathed on a nice coat of something with a brush.

Have you tried POR-15? http://www.por15.com/

heh, yeah, pricey....
they supposedly sandblasted the inside, then used baked the coatings on
when i got it back from ye ole radiator shoppe, it still had crap inside of the tank after him attempting to clean out the tank for a month... he finally said metal was too thin
i might of tried the por15 if i had known about it, but their work was warrenteed, and i was in better to have done right than messed up by me.

that was then, this is now---
now that i realized ive spent way too much on random crap, an now i'm trying to do it on the cheap.  i justified the tank price because i picked up my original project truck for about $635 (i say about, because i drove down into the hell that is bakersfield and trailered it back to vegas, and my time and effort is priceless.. )i want to repaint the bed of the truck, and i'll have to give the por15 a shot (although the self etching stuff at wal-mart might do in a pinch...)

my 2 cents.....

If you want to restore the inside of a gas tank, do some research on rust removal using molasses.  There are some antique tractor sites out there with some good info.  You can get the molasses from a farm store or feed store for a couple of $'s.  You basically mix it will water and fill the tank....let it sit for a couple of weeks to ferment and it eats all the rust, but doesn't touch the good metal.  You can dump it on your lawn since it's simply fermented sugar.

When we bought my wife's 521, it came with the tank out because the guy had done the molasses thing to it.....but he broke some bolts and couldn't get it back in. 

As for the POR15....that stuff's pretty dang expensive!  Also....watch out with the self etching primers....they're acid based and from what I hear, most of the other paints will not go over them, you have to put down a sealer first.  I don't know this for sure, but you may want to check it out before you do it.

Yeah, POR-15 ain’t cheap but, it does[/i] work great. I actually have never bought it retail ‘cause, thanks to California’s ridiculously stringent but, necessary environmental legal wrangling, the laws concerning commercial use of paint and solvents changes every year. So I head to a swap meet where I know a body shop guy who unloads his “illegal� paint for cheap. He always has a couple of quarts of POR-15 on hand.

 

Your mention of the molasses trick is something I haven’t heard of since I was teenage tractor boy in South Dakota. A windmill / pump shop old timer guy I worked with talked about using “molasses� on a rusty plow blade once. I just thought it was some sort of farmer slang terminology for something else. I didn’t think that was real pancake syrup he was talking about. I’m gonna have to look into that and see if it actually works.

Okay....here's a few links I've collected on the molasses and gas tank subject. 

You can use the molasses that you use on pancakes, but if you're mixing up more than a gallon, you'll want to go to a farm supply store and get the stuff they mix with grain for cattle....much cheaper.

I didn't look at them closely while I was doing this, but I think 7 & 8 have the most molasses info.

I've got to do the tank on my NL soon, so I may be picking some up today or tomorrow to get that started.
