Not far enough... :P

When you get your fuel pump out you'll have a much better idea. ;)

Definitely can't see all of it.

Not trying to be a wiseguy but if you cannot see most of it why worry about what color it is?  I have coated mine allready......

Sometimes it makes it easier to determine how things are flowing if you can see the coating.

Best way IMHO is to wash thoroughly with lukewarm water and hand wash soap (Palmolive, take me away..)  Do this a few times until the surface feels clean.  Sounds stupid, but gasoline is "slippery" and you can feel it on the surface.  The smell will persist for a while.


in order to do it this route, you just pour in the soap/water and just agitate it and it will rinse out eventually?

tank is off the bike now and i'm prepping it for the caswell... wanted to make sure that i didnt have to try to scrub it in some fashion that i cant for the life of me figure out how to do.  haha

That should be fine.  You're just trying to solublize the gas remaining.

kk, just finished the coating... and here are my thoughts on it... and these are based off of doing it on a m796

a) masking tape everything... the epoxy gets everywhere, so even though the the new monster tanks are covered with the plastic skins so you wont see the extra epoxy, the masking tape is way easier to get off than the epoxy. it makes it nicer overall.  wearing some rubber gloves is also nice when mixing/pouring the stuff in.

b) without thinner, i cant see how anyone could get this to cover anything before it cures.  i wound up using the whole bottle because the first batch i mixed up had way too little thinner.  it moved about the same speed as slow molasses, which was making it impossible to get it to coat anything.  the issue was that i put the thinner into the a component of the epoxy thinking that it wouldnt thicken that much more that quickly once combined with the b component... which it did.  i would suggest tossing a bit of thinner into a first, and then adjusting the thickness with a dash or two of thinner after you mix in b.  the second batch flowed about the same speed as honey... which was slow, but doable.  and that much thinner with greatly increased the time before it cured... which also forces you to keep moving it around a lot till it does.

c) for the new monster tanks, make sure you get the tops of the bumps inside the tank.  the bumps are from where there are any screw holes on the outside... and then epoxy tends to just flow around the bumps as opposed to over them, leaving the tops uncovered. i used a long stick to push the epoxy around to get the coverage.  i got every one i could see, and tried to move around the epoxy as much as possible in the parts i couldnt see/reach

d) i agree with dp that you can use a half can for the whole tank easily if it's the correct viscosity

I plan to finally coat my S2R the tank this weekend. I washed it a few days ago by first filling it halfway with lukewarm water and dishsoap followed by two rounds of a 1:1 (cup each) ratio of luke warm water and POR Marine Clean fully rinsing between each cleaning cycle. I checked the tank last night and I still have a slight gas odor. Felt the area inside where the fuel pump mounts and it did not feel oily, but it's sort of hard to tell since the material is naturally slick.

I am wondering if I should pour in a bottle of rubbing alcohol? Drain and let evaporate with out a water rinse. Might be a bad idea since ethanol is causing the problems. Maybe another round of cleaning with the Marine Clean? Part of me realizes that the gas smell will never go away, but the other part is nervous about painting something that smells like gasoline.

Alcohol won't remove the petrochemicals.

The 'Marine Clean' instructions say it needs to be in the tank for a minimum of 20 minutes. If you accomplished that with your two cleaning cycles you should be fine.

I finally got around to coating the tank this weekend. All in all it was pretty painless.  

What I did:

1. Prepped the tank by washing it first with lukewarm water and dish soap followed by two washes using a 1:1 mix of POR's Marine clean and warm water. (Keep in mind this is a used tank. I just purchased the bike, it's an '07 w/ 400 miles. So while not a lot of gas has been through it its had gas in it since  '07.)
2. Sealed fuel pump opening w/ 1/8" plexiglas and plumbers putty
3. Coated tank with blue painters tape.
4. Mixed the Casswell kit in half batches each thinned with one once of Xylene - per ducpainter's recommendation
5. Poured first batch in and moved the tank around for about 15 minutes until I could not see much flowing down to the plexiglas window when I stood the tank up.
6. I then inverted it over an aluminum foil roasting pan inside a cardboard box. The box lets you easily position the tank to get the filler neck at the lowest point to drain any excess. I didn't get much out after the first batch and the coating stayed fluid longer than I expected. I noticed the coating was dripping from the bottom of the tank to the top when it was inverted.  I would flip the tank every 10 minutes and if any material pooled by the fuel pump opening I would stand it up and let it run to the front. This also gave me a chance to clean out the filler neck.  
7. After about an hour and and a half the coating inside the tank had thickened up quite a bit and I applied the second coat. I got more out after I inverted it this time,  but would still rotate the tank every 10 minutes or so for the next hour to ensure uniform coverage. The picture below is the entire amount that came out after both applications.


What I would do different:

1. Remove the plexi window after the final coat has set up initially. I removed mine the next day and as soon as I looked at it I knew I should have done it sooner. Since the coating on the glass is one with the coating in the tank it made it hard to remove and it removed a little bit of the coating around the fuel pump opening when prying it off.
2. Maybe thin it a little less. I had my garage @ 65 deg. and it flowed like warm honey and was very workable. Thinning it less could have prevented the need from having to invert the tank back and forth. However, while I was babysitting it, I did chop the tail.


All in all I am pleased with the results. Lets hope it holds up and prevents any deformation.


Good Luck

Keep posting Information on results if you have recently coated your tank.  Tell us how it went!

If you are coating a new tank I'd skip both.

The drywall screws don't accomplish enough to justify the time IMO.

If you're coating a used tank that's had fuel in it acetone won't do squat.

That tank should be washed out with soap and water to remove fuel residue, POR makes a graet cleaner called 'Marine Clean', then allowed to thoroughly dry before coating.

Checking my understanding, is it necessary to wash out a virgin, never-seen-gas, tank with acetone, soap and water, or Marine Clean?  Can I can skip this wash-and-dry step and get straight to lining?  I want to get this prep step right.

Thanks,
Jeff
