It all looks to me to be a gray rubbery coating, anyone know the maker or a good substitute? does one need to remove the existing or can I coat over the old one? some areas are lifting around the sender, overall still ok.
is there gas tank porn also?
thanks
Hi Richard.
Yes, there is lots of good gas tank info. I just competed a complete tank restoration for my '69T. I plan to publish it here soon. I used a compiltation of the many excellent recommendations here.
Here a few pictures:
Final pic...
Most of my work was focued on restoration of the interior of the tank.
I'll gladly expand upon the post if anyone is interested.
Regards,
Bill
nice work Bill, whats the stuff in the larger bottle ...ends in pho?
could you detail the process? does the gun use a bottle or screw in the SKS?
I am getting ready to restore 2 gas tanks. I would love to see more.
OSPHO by Skyco. It's a phosphoric acid solution found at auto paint supply shops for about $20/ qt. It treats the metal and passivates it and there is a conversion of iron oxide to iron???. I used it after a battery failure and the rust was treated with this to make it ready for primer. I will venture to say that it is the best I have used.Quote:

FYI everyone - This should help save a little time in removing undercoat. When stripping Wurth SKS know that the material is PVC based. You will need a stripper that is a solvent to PVC, many strippers are not. I found a stripper at a hardware store (Home Depot) sold under the name: "Citristrip". This Gel stripper works well on all gas tank and undercoating areas, much better than a conventional paint stripper. You will need multiple coats in between scraping and wire brushing.
I used the orange stripper in conjunction with a large Milwaukee angle grinder with a heavy duty wire brush attachment to remove the loosened up old SKS. You will need a large amount of power and a large wire brush attachment (a twisted wire brush works very well too) otherwise it will take a significant amount of time to scrape off the old coating. Anyway you look at it restoring a 911/912 fuel tank is a hard job but necessary.
CAREFUL IF YOU HAVE A 1973.5 CIS CAR WITH A 1/2 YEAR ONLY RARE FUEL TANK. These tanks are only for the 2.4L CIS system and should not be mixed with tanks from other cars.
I have an extra restored short wheel base tank available if anyone wants to skip the restoration hassle and buy one outright.
