Gas Tank

Does anyone have any good ideas for cleaning out a 28 yr old gas tank. Mine has a lot of rust inside. Eastwood has some chemicals, but has anyone tried them. Any help will be greatly appreciated. I was even thinking about some carb dip sloshed around in there to clean out the old gas that had gone bad. But that still leaves the rust problem. Thanks.

gas tank

i just did cleaned mine bout 3 weeks ago. Take it to a reputable radiator shop. They can dip it in their tanks and remove all the corrosion inside. It took 2 dips for my tank. The shop owner said he'd never seen a tank that old look so good. Afterwards, i coated the outside with 3M undercoating.

Dipping at radiator shop $65.00
3M undercoating $ 3.00
------
$68.00 and i'm very pleased

Many thanks

I just happen to have a friend in the radiator business. I will take him the tank and the radiator at the same time. Yours looks great after the cleaning and painting. Thanks for the tip.

Nice!

...but what about the interior? I don't even know the brand name, but I do know there is a coating/lining product, likely on the market for motorcycle tanks/antique auto restorations, to seal the inside of a tank that has had rust removed... always nice to prevent further deterioration... no matter how well the radiator shop was able to clean it.
Other rust on yer rusty REPU needs the "ospho" treatment, after thorough brushing/sanding/grinding: a phosphoric acid dilution that converts remaining, unremovable rust to a black oxide... when done properly, with very thorough prep, provides a good basis for primer/filler, etc...

Wow...

Now, *thats* what I'm talking about...

I wish I could have every peice of my REPU looking that good. I think I'm going to try to make my REPU as much of a "show" truck as possible, while still being able to use it every day, and still be able to toast most everything on the road. :)

Radiator shop

Well my radiator shop owner friend has come thru for me again. He said he and another shop in Nashville are the only 2 in the area that take gas tanks. He said the process takes him about a week to do. He dips it until all the rust is gone and then he coates the inside with a sealer. I'm sure he'll paint the outside too. He paints everything black. I'll take him the radiator and oil cooler at the same time to check and clean. Thanks for the tips and keep the pic's coming. I'll take some before and after pics for the web site.

oil cooler

i was wondering if radiator shops would do oil coolers?? I thought they might not cause the residual oil might gunk up their tanks.

good point

You have a very good point, I didn't take the oil cooler off yet to take to him. I will check with him when I pick up the radiator and tank. I will probably take it off and try to flush it out with some type of solvent to clean the old oil out. I have some old carb cleaner that seems to work wonders on bolts and small parts if I can determine if it will harm the Aluminum in the cooler. If it was clean of all the old oil I'm sure he'll dip it and clean the fins out.

Most importantly:

whatever methods you choose to use, remember the oil cooler is where any metal in the oil will have likely deposited...whether from engine break-ins and/or engine failures over the years... so how clean it gets on the inside is much more important than the outside! I'd flush the lines, too, while yer at it...
Carb. cleaner generally is safe for any type of metals...it's the rubber/plastic/leather components you've gotta watch out for...
