What is the best way to seal your tank when you have a rusty interior to deal with?
Should I powdercoat my tank before or after the process?

i did one with muratic acid from the pool supply store , rinse thoroughly with water then used redkote and was happy with the process . After coating I painted so i'm not sure how the heat would affect it. Personally I would powder it first but i'm sure more experienced builders will chime in on that

I've restored several tanks, but have not powdercoated one yet.
Drain the old gas, pour in some new, fresh gas and swish it around to rinse out loose rust, varnish, and other crap. Drain that, and let it dry. Muratic acid from a pool supply store or Home Depot will clean the tank of ANYTHING in it - old gas, rust, whatever - the acid will eat right through it. In fact, if you leave it too long, it'll eat right through than metal itself. After draining the acid, rinse with water, then use a stong cleaner like Castrol Super Clean to neutralize anything left. Coat the tank with Kreem, let it sit at least 24 hours, then test it for leaks with water. If it's good, dry it out and you're ready to go.
Do bodywork and paint on the outside of the tank AFTER you've cleaned the inside, or you'll be doing it twice.

i'm no expert on the cream liner. but i would clean the tank, then have it powdercoated before using the liner. because of the baking in the oven to cure the powder coating, would probably do something bad to the sealer.

I have read in a few different places that KREEM is not the way to go and that I should not lie it unless I have pin holes or something leaking.
POR-15 is always popular with everybody, but I have never been a huge fan of the stuff. Has anyone had any issues with it?
What about sealing something in the tank that does not need to be sealed? Return and petcock holes?
Sorry to ask a bunch of questions...the last thing I want to do is complete my restoration only to send junk into my fresh motor and stop up my jets?

I have used the POR-15 kits a few times now, with good sucess... (Kreem sucks IMO) You remove petcocks and gas caps before the process. Follow the directions exactly, and it takes about a week to do it right... I have done my last 2 tanks after they were painted without issue...
No trikes. Too old, too crippled. Unless I find one I can't live without!

Catch me if you can
Im used redcoat, worked fine.....
But 400 degrees for 20 minutes may not be so good.

What I guess I am going to do is let the radiator shop dip / strip it, take it to the powder coater, then if need be use Red Kote afterward.
I only want to line the tank if I absolutely have to.

I just repaired a BR 200es tank using the POR-15 products. Easy to use and is working just fine so far.

PC-7 is a good product to if you want to do a quick repair,if you want to seal the inside you just mixt it with acetone,work very good I did one last year and still no leak.

I used Phosphoric acid to clean some light surface rust from the inside of my BR fuel tank. It worked like a charm. It's also probably a bit weaker than muriatic acid too. I got it on my fingers a bunch of times, it stings a bit but didn't remove any of them. Lol!
You can get it at Lowes or Home Depot for about $20/gallon. It also does a great job cleaning rusty bolts and hardware (soak them overnight). Be sure to wash and dry them really well before painting/plating them.
