I have recently completely rebuilt my 1974 Penton Jackpiner MX only to discover carb and other issues with what appears to be gas tank disolving ( from what I have read from old message board entries ) caused by the 10% Ethanol in our pump gas here in Missouri. Can anyone tell me if the Casswell Tank Sealer Kit is the best solution to this problem? Much Thanks
Caswells sealer is A good product, and supposedly works well on fiberglass tanks. I personally prefer POR-15 Clear, as it is designed to be used as a fiberglass resin and bonds directly to a properly prepared fiberglass tank. It is impervious to all chemicals including Alchohol and Laquer thinner, and I will be coating some tanks prior to Mid-Ohio for Mike Gallagher, as long as the POR-15 Clear arrives here in time. If so, these tanks will be delivered to Mid-Ohio, so if you want to see the results first hand, stop by my spaces 193 & 195 across from the Penton Owners Group on top of the hill by the oil reclamation tanks.

cbarmeir,
Welcome to the group!!! Of all the Motorcycle boards out there, these guys are the BEST!
Your question was one of my 1st questions too! I lucked out and was able to pull my tank off drain the gas and clean it out with soap and water with out any damage. I caught it in time, but it was disolving.
I know this topic has been covered many times and if you do a search on the message board you will find an bunch of responses.
Also do a search on what type of fuel to use. I now use VP C-12 in my 6-day.
Also do a search on "how to post a pic" We like to see befor and afters.
Again Welcome to the group.

Use either ethanol free gasoline. (You can test gas with a jar with screw top. Make a line about 1/5 way up jar from bottom. Fill to line with water. Fill jar rest of way with the Gas. Shake and wait for it to settle. It it has ethanol the water level will now be above the line you marked.) I suggest 100LL Avgas with about 20% race gas. You don't need more much more than 100 octane.
I'm just getting started on the learning curve regarding alternatives to E-10. 100LL AvGas is available to me locally. Since it is already a bit higer octane than the premium pump gas I normally used prior to E-10, wouldn't it be OK to use as a direct replacement for the "old" premium gas without blending with race gas?

Keep the rubber side down!
No, not really. Straight AvGas is blended for low compression, High altitude, low RPM engines that run at a constant RPM. Straight AvGas suffers weak throttle response. A bit of Race gas gives it back enough additives to give it back some snap. You can even use lead free race gas as 100LL has more lead than auto or MoGas ever had. A good point of AvGas is that it lasts much longer than MoGas.
You can also use marine gas purchased at your local boat dock. It contains no Ethanol and doesn't damage glass tanks. I still store fiberglass tanks dry because it makes me happy!

Too much of a good thing?
Thanks Dwight. I figured you'd be a good guy to ask, what with one of your feet on a rudder pedal and the other on a foot peg!
Ed
Keep the rubber side down!
Britt, Thank you for that great suggestion about using marine pump gas. That's right; many boat gas tanks have been made of fiberglass in the past. Boat docks and marinas are numerous out here in Northern Ohio along the Lake Erie coastline. Joe
For anyone from Pennsylvania, Kwik Fill stations don't have ethanol in their gas as of yet. I don't know if they're in any neighboring states or not.
Alan
Caswell will break down. I have had it happen with a Bultaco tank. The only solution is race gas or marine gas.
Mike Winter,
The Por 15 product you mention, is it their US Standard Fuel Tank Sealer or another one of their products?
Thanks,
Scott
POR-15 Clear Paint, not tank sealer or 2 part epoxy. Mike

Glisten PC or Pelucid
I do not use Glisten PC or Pelucid, only POR-15 Clear paint. The paint is impervious to all chemicals, I am not sure how the the others would react. Mike

I have purchased Cam II race fuel from my local Marathon Station. It is blended by Sunoco and is a leaded high octane non ethanol fuel. I have left it in the tank for a few weeks and looks ok, does any one know if it will cause problems?
I usw Cam2 and have had no problems as of yet. I mix it half and half with Sunoco 94 and add Stabil. But, I also drain it after use and let the tank air out.
Mike Winter, or other POR-15 users,
What method do you use to prep the tanks for painting with clear POR-15? The POR literature suggests a "Marine Clean" product for removing fuel residue and varnish, but they only refer to using it on steel. My concern is that the Marine Clean might penetrate the fiberglass and cause other problems. The POR literature also mentions that fuel residue MUST be removed for POR-15 to adhere properly.
Another question - has anyone used POR-15 on plastic reproduction tanks to keep the decals from lifting?
Thanks for any help,
Jim Dale

Do a search on Decals its covered in the search area.

Do a search on POR-15 and you can find explicit instuctions on the use of POR-15 Clear. POR-15 will NOT adhere to plastic tanks and I recommend this ONLY for use on Fiberglass Tanks. Mike

Thanks Garrett and Mike,
I will try to be more thorough in my research before posting questions. The POR-15 dealer that I ordered from stated that it will work on plastic, but I trust the members here to have tried it and to know that it will not adhere. I do have several fiberglass tanks that I will be treating per Mike's instructions.
Jim
I can peel POR-15 out of the plastic mixing cups that I use, so adherence to plastic is not acceptable in my opinion. Mike

the search engine is great, but, please ask if you have a question. Like I stated these guys are the best. TRUST ME, I've asked every question imaginable.

I posted a month or so ago that Kwik Fill gas, available in Pennsylvania, didn't contain any ethanol but that has changed in the last few weeks. Hope I didn't mis-inform anyone.
Alan
I have had several questions from Poggers on the POR-15 used on the tank I have on eBay so I am bumping this up. Hope it helps those that have not already seen it.
Larry P
I used to use Sunoco 110. But no more. On my bikes using either 40% race/regular or running it @100% made it run hot. Using a 32:1 mix.
