I had a few listers ask about my findings, so here goes:
The following is correspondence with:

They were very prompt and friendly with their e-mail
and have a decent Web Site. Check it out! >>>>>>>>>>>>>
>Just got off your website.
>I have two gas tanks I would like done.
>
>1. Jeep M-38 type, similar to the old CJ-3A. Some time back, I placed
>an after market plastic coat inside. I see now that it has bubbled.
Underneath
>the bubbles the tank is corroded. I also have some pitting and pin holes
>in the bottom.
>>$125 plus $35 to remove old coating.
>Can your process remove this coating?
>>Yes, we remove this coating every day.
>2. Jeep (Ford GPW) tank, similar to the old CJ-2A. Some surface
>rust, and a pop rivet. Yup, thats how I got it.
>> We will have to see the tank to give a fair quote. If you do send both
tanks,
>>we will be more than fair with the cost.
>3.Will the RENU coating flex enough when the temperature
>drops to -30/-40 F degress? We do get that here. The concern is any pinholes
>that would normally get sealed.
>>We process tanks for northern Canada and Alaska and haven't had any
problems.
>>Would you like me to send you a sample piece of processed tank?
>>You can freeze it, bend it, whatever you like.
>4.Do you have to punch extra holes in the tank for the "RENU" process?
>I spoke to a fellow restorer, that said he was going to have a new tank
>done, for the extra protection, but found that holes had to be drilled.
>He wasn't to wild about holing a good tight fuel tank.
>>We drill a small hole in the corner of the tank to drain out all the old
fuel. Then we weld in a plug and process >>over it. A new tank will not
need that hole. However, we have to completely sandblast the inside of the
tank >>and if we cannot get to a particualr section, we have to open up the
tank. If there is a plastic bowl inside, we >>make a new metal one and
process over it. If there are baffles, we have to clean each one. The
most important >>step in this process is the one the customer cannot see.
The inside has to be absolutely clean.

E-mail from some listers:
1.Yes, I have and it works fine. I used it in air compressor tanks in my
repair
business.
2.We had the fuel tank on a customers CJ-3a "Renu'd" (inside & out) about 12
years ago. It hasn't leaked since. And there have been no problems with
foreign matter in the fuel filter either.
If it is coated inside & out, you get a lifetime warranty.
3.A friend of mine had a tank done with this that was rotted out, lots of pin
holes. It is still in service 8 or so years later. I was going to have a
new tank coated to help extend it's life but it turns out that part of the
process is to drill holes in the tank. I didn't want my brand new tank to
end up with holes in it just to have it sealed so I decided not to do that.
I ended up using a tank sealer called Kreem, very happy with the results.
4.*My question to a lister:
Regarding "RENU", did they have to drill extra holes in the fuel tank
to do the process?
*His answer:
I don't remember any new holes in the fueltank. Its rather hard to tell, as
the coating is thick & not totally smooth.
5.What did you find out? I see them doing 3-4 more tanks a day
but I have never had one done.
I know thay have to sandblast the inside
and thay gas weld it back shut after cutting it open or if working thru a
rust out hole thay gas weld a patch on it.

My conclusion:
My M-38 tank has a baffle that seems easily accessible from either side,
tank filler tube on one side and the tank gauge/fuel filter ports on the
other side.
It has some pitting over a small section on the bottom.
The GPW tank hasn't any baffle. It has the pop rivet and some surface
rust on a partial side.
With any luck, the RENU process shouldn't require any extra "holes".
The sandblasting will remove the tin plating of the tank, hence the thorough
coating inside and out. RENU should also eliminate any tank rusting of the
bottom
when they are mounted inside a vehicle like the 1/4 Ton Jeeps, etc.
My tanks are definitly worth saving. Biggest effort, once I remove
two broken screw studs in the fuel sensor ring of the GPW will be
safely packing them so that they survive the UPS trip.
OK, 2nd biggest effort will be the cash.
a. I've priced new tanks.
b. I really hate to trash these, we been through alot together.
I picked up lots of cardboard from a furniture store. They were happy
to get rid of the extra cartons.
Didn't mean to leave listers out of the loop and hope this info helps.
