I put some diluted miratic acid in mine rinse then sealed with some sealer from macs.It was really easy.
Thanks a bunch for the suggestions. I'll check it out. I know that Edgewood sells a kit. Anyone tried it? I haven't dropped the tank yet, so who knows. It could be rusty and require repair. Hoping to get to that this weekend. Thanks again.
The more I hear about doing this, the less I'm apt to do it. I have a couple of tanks that were done years ago and it seems like with the gas (if you want to call it that) the sealants that are available aren't up to the task. There have been a couple of discussions on the FordBarn about this. I'd be more inclined to find another tank (a good one) or build a tank.
por tank restore get some marine clean let soak inside tank for a day or so then drain let dry then use metal etch swish around inside tank puor back into container as this can be reused let dry then pour por tank restore in swish around and puor out and let dry for 72 hrs tank will have armored shell inside works awesome have used it many times also mif any repairs were made also fills in any little pin holes you might get from repair
I just did mine using the POR 15 gas tank restoration kit...$73.00. See pix of before and after. I posted a thread on it. I called gas tank RE NU in Stockton, and asked about the process. They said they drill as many 7/8" holes as needed in the tank to media blast it, and then solder the holes back up, and seal it. Wasn't too keen on RE NU making all those holes and used POR 15.
