It makes sense to me that thinning and pouring the whole kit into the tank is the way to go.  I'd rather have a tidal wave of product flowing over the islands and flooding the valleys.  I plan to get comfortable in front of the TV with the tank and rotate it as long as necessary until it begins to set up. 

But, I haven't gotten to that stage, so there's still time to convince me otherwise.

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.

excellent points, thanks

All 50 screws are now accounted for, the tank washed with Dawn, and is currently drying upside down with a hair dryer set on no heat blowing through the fuel flange opening.  Next step, lining!

Can anyone tell me the distance between the centers of the frame pad screw heads measured across the bottom of the tank?  I meant to measure this distance before washing the tank, so I could track swelling from the water and determine when I am finished drying.

Thanks,
Jeff

I measured off the holes, the rear ones

290mm center to center.  That's off a tank that's never had gas in it.

Thanks.  Do you agree that is the right dimension to let me know I am safe to line?

What is the best method for masking and plugging the fuel filler opening while lining?  When I washed the tank, I rolled up a sock, wrapped it plastic wrap, and plugged the opening.  It worked well, but I want to ensure I get maximum coverage with the Caswell's without interfering with the fuel fill door seal or latch. 

What do you guys think about reinstalling the filler door, laying plastic wrap across the opening and latching the door shut over it?  The plastic wrap would act like a condom and protect the filler door, latch and seal.

I have a #10 rubber stopper that fits the fuel opening. I think I'd avoid using the cap only because of the possibility of the latch lugs tearing the plastic wrap. Duct tape?

I made a plate out of plexi-glass for the pump flange, and seal it with automotive strip caulk. You only need three bolts spread around the circumference.

I have two tanks on hand (well, three if you count the donor S4RS tank) and all of them measure about the same.  ~292-295mm.  the virgin tank reads about 292 and the used tank is 295  That is pretty close and I'd say some normal variation is likely.  The rubber pads are adjustable and I think that's why.  the used tank has been washed and dried and has sat up for the last 4 months.

Did you put the stopper in from the outside or the inside?  I used a #9 and reached in and stuffed it in the hole from the inside.

My plexiglass cover for the bottom had a #10 sized hole and I used that to pour and put a stopper in it to agitate. 

I used cork material to make a gasket for the bottom and all 6 screws.  One could probably use some of that adhesive foam seal.  The coating isn't particularly liquid so it's not going to seek leaks aggressively like water would.

One more thing, I recommend lancing the "boils" on the interior of the tank.

If you look inside, you'll see air pockets in the surface.  They have a VERY thin layer of material on top and if you coat without removing it, the coating is sitting on top of a fragile surface.  I used a small exacto knife and cut some of that dome off so the coating would get inside the cavity.  As far as I can tell they are only on the TOP inside surface. 

You can't get all of them but try to get as many as you can.  Even if you only puncture them and leave enough of a hole for the coating to get in it should be enough.

Outside.

I used to use the same system of blocking SBK tanks I use POR on and I've found the strip caulk to be effective for the POR chemicals, so I just stuck with it.

I bought some large diameter expanding plugs to get it done faster.

How did you reach inside the tank to remove the plug without disturbing the coating?

let it dry.  Reach in with your fingernail or exacto and cut a little around the plug.  i used the exacto first and then realized i could do it with a fingernail easier. you just need to make a small cut so you get a clean break.

if you have ham hock arms it won't be easy.  i'm not small either and i can do it.

the plug is on the filler funnel which isn't nylon, it's something else (HDPE). pull it straight down and you get a clean break.

Mine measured 286-287mm the day after I washed the tank.  I guess my tank did not swell much from the quick cold water wash.

We have had unusually low humidity levels (30-50%) since yesterday and continuing through tomorrow.  I plan to take advantage of the dry air and line my tank tomorrow or three days after washing.

Are you measuring the front or back holes?  Centers?

I am surprised if there is that much variance, but I guess it's possible.  The bumpers have about 5mm each lateral adjustment.
