I am going to want to seal the fuel tank on my car. I did a search and their seems to be alot of choices. I want something that wont be effected by ethanol. What do you suggest? Thanks, Todd
stainless steel! Although if not the por-15 is the best way to go. We used it on industrial tanks for generators(semi-trailer generators). All the other stuff will eventually flake off and fuc up your fuel system.
I used Redcote in a 1924 gas tank that I had professionally cooked out. It's been about a year, with no apparent side effects other than the gas (seen through the gl*** fuel filter) had a reddish tinge to it for a month or so. I have paper thin blob of it out in the garage that is still flexible.
????????.........................I investigated this stuff, ( we have it at work, and was going to try some of it with an expired shelf life....), and the 3M cat told me not to use it with gasoline, as the alcohol in the gas would cause problems........................In the literature, it states: "to use alcohol for cleanup".........................
im using the red coat stuff in mine now, it was recommended by the fella who boiled out the inch and a half of sludge. i have also used milky white stuff in a new motorcycle tank to seal it. not sure if its good for old tanks or what, but u could find it from a biker catalog maybe.
bgaro, I think the stuff you are talking about is Kream. I have used it on lots of new and old Motorcycle tanks and it held up well IF you prep it right. If you rush the etching process it will peel off within weeks. If done right, It seems to last quite a long time with high octane fuels. I have heard of a lot of people having problems with it though but attribute that to improper etching.
Good info here. Ethanol has caused immeasurable problems with boats, cars, and motorcycles. BMW had a customer callback for in tank fuel prepumps. (BMWs have access doors to the fuel gauge/prepumps, so the tanks didn't have to be dropped) When out of warranty, this can be costly... My son has an almost new Reinel boat with a 305 Chev in it. The pump shed its inner coating (!) and would have been an expensive replacement...thrifty machinist son tore it apart, removed all protective coating, fashioned new seals, and installed it. Problem gone, 305 now runs like a 350.
Seriously if at all possible build or buy a new tank. But Thats just me .. I dont believe in all the snake oil rust sealers / converters and such. To me its get the hell rid of it if you can. When I take short cuts .. seems like they always come back with that ***hole Murphy to visit.
Pod-15 works well we've had it in some cars for years with no issues...some times new takes aren't available and if yout want your car original then you have to reuse what you have....por 15 is the best out there
Sorry if this is a stupid question, but if you get the tank clean enough (boiled out professionally, or some other way) is it always necessary to use a sealer afterwards?
Been using this stuff on my old rides for years anit had no trouble with it at all, Used by Airplane guys to seal avgas wet tanks Alcohol for Clean up" WTF Alcohol for Drinking and going fast seems a dam waste for clean up Hicup"
Ive used POR 15 twice now and had bad results both times, one tank I spilt open at the seam had sandblasted and re welded it back up, followed all the instructions to the letter with the etching process etc. The stuff started peeling off in sheets withen days of putting back into the car. Just split a motorbike tank and was wanting to seal it but With previous experience I may just leave it.
KBS Coatings. No problems whatsoever. I had a new tank, but had a Moroso sump installed. I didnt want it to rust at the welds or leak from any tiny pinholes. I believe the key is take your time with it, and let it fully dry out in between steps.
Por 15, I have had no problems with it in the tank we did, **** I hope i dont jinx myself writing that
