not too bad its epoxy.  if you thin kit with a solvent like xylene then you get fumes

So follow up on my experience. Finished the work a couple of days ago. I ended up using xylene as I mentioned prior. The temperature was pretty cold outside so I heated up the garage with a space heater up to 70 degrees.

IF YOU USE XYLENE LIKE I DID. DONT USE 1 OZ FOR THINNING.

The stuff stayed liquid for a long long time (almost an hour and a half). I was getting a little worried this crap wasn't going to set but it did. I would recommend 1/2 oz with pure xylene as recommended by the manufacturer. Due to the thinning properties, I actually had a lot left over but, luckily, I had enough time to siphon off the excess from the bottom flange hole.

TAPE EVERYTHING ON THE TANK THATS CLEAR COATED. DONT BE LAZY AND SKIP THIS STEP. I wrapped1 inch around to the inside.

If you have a monster tank (Mine was an S2R 800), you wont be able to drain anything out of the gas filler hole. Its got a weird upside down speed bump style hump on the inside of the filler hole so material tends to pond around the filler hole instead of draining out If it is draining out, you probably have a lot left over inside. As mentioned earlier, I was able to siphon off the excess from the bottom flange using a turkey baster (and patience). Out of the 13 oz total put in (8 oz part A, 4 oz part B, 1 oz thinner), I was able to probably pull out a good 4-5 oz  back out. Your results might vary if you have less thinning agent.

Other than the fact that my coat ended up looking like shiny glass its really hard to tell anything is even on there. This stuff has no tint what so ever.

Overall the project was a success. now to figure out what the hell I'm going to do with the other half of the unused sealer.

too late, tanks already getting retrofitted onto the bike by the dealer.

Has anyone tried using some sort of swab to mop the coating to ensure all surfaced are lined?  I'm wondering if even something as simple as a piece of sponge on a coat hanger would improve coverage.  Maybe mop the first coat then flow the second coat?  Thoughts?

My experience was that it was very easy to coat. But I used 1 oz of xylene thinner. I took a peek after it had hardened and I didnt see one missed spot.

That being said, from my post above, mine was runny for a while longer than most.I attribute that to the xylene. I had no issues with coating in time. If you mix the thinner completely into part A before you put any of part b in, you'll get a consistent product. Shake it up in a sealed glass jar thats at least twice the volume of your final mixture. I used a cleaned out RAGU pasta sauce mason jar and shook the mixture for almost 3 minutes straight.

My Caswell's kit is on its way.  Does it make sense to wipe the interior of a new virgin tank with alcohol or something before lining?

I dont think its worth it. You're not going to get that far in. I didnt even bother, but drywall screws are, in my opinion, better if you are going to do it. Just count how many go in and how many come out.

wash it out with a water based solvent.  caswells sells a tank rinse which is good.  don't rinse it with alcohol.

make sure to let it dry -- hair dryer on no heat for a few days.

I dunno if you really need to do a rinse on a virgin tank. It doesnt do any harm if you have the time. I did however jam a leaf blower through both openings for about 10 minutes to blow any crud out of the tank before I started

I am well into the preparation phase of my tank lining project of my virgin, never-seen-fuel tank.  Unsatisfied with the amount of surface area I could hit with a brush, I ignored the sage advice on this forum and did the drywall screw thing to scuff up the interior surface to improve chances of Caswell's adhesion.

Of the 50 drywall screws that entered the tank, as of this moment, I have retrieved 47.  The remaining three are being a bit stubborn.  I was able to get the last couple to emerge (I was missing five) by warming the underside of the tank with a hair dryer to expand the interior enough to dislodge screws stuck in the side saddles of the tank.  I'll continue working on it tonight before moving on to the washing phase. 

Even though my tank is virgin, I think I will go ahead and wash out the tank with Dawn dish soap and water to remove the oils from my hand and forearm that have now spent a lot of time inside the tank.  Plus, I'm sure the screws weren't squeaky clean. 

Oh, after having a lot of time to study the complex shape of the interior of the tank, I am leaning toward mixing all the Caswell's, reducing it with 1 oz. of Xylene, and flooding the cavities with Caswell's in one big shot to improve the chances of 100% coverage.  Thoughts?

Toldja not to use the nails.. :-)

I would get one of those 100lb magnets from harbor freight and stick in in and see if that will do it.  Don't let go of it..

I am leery of making the solution so reduced so it flows too easily.  I think you will want a little bit of control in the process and too much liquidity = bad.

Also I think two coats is better than one thick one.  You could even go as far as to coat once -- cure and then coat again and cure with the tank sitting opposite the 1st cure to make sure it doesn't settle during cure.  That might be over kill.  But if you're going to reduce it that much, then you'll definitely need to keep it moving.

I reduce that much...maybe more.

It assures coverage in one coat even if you have to 'work' it more.

YMMV

You don't think doing it in two coats would be better?

I think it's unnecessary.

The product was designed to repair perforated steel tanks.

It's the consistency it is so it doesn't run out of the holes.

With a plastic tank coverage is more important, and it is far easier to assure complete coverage by reducing the product to a point that it flows easily.

As packaged, the stuff is virtually impossible to get it to flow over all surfaces inside a tank...I don't care how many coats you use.

It is true that you have to rotate the tank for a longer period of time to avoid 'pooling' if you reduce.
