tank liner & chrome

[coxy]

g day all
i am going to get another gas tank chromed this year would it be possible to line the tank prior to chroming to avoid the rust problem or would the liner disrupt the chroming process cheers

 I would think that by the time you clean it inside and out enough to know its solid, you probably wouldn't need to line it? I clean a lot of them out with acid solution and if they don't pinhole, I swish them out with mixed 2 stroke gas and skip the liner.  Mark.

I dont believe you need to line the tank. Check out my post in the "How To" section. Treating the interior tank rust with EVAPORUST gets rid of the rust and then you can just keep the tank full of gas afterwards to prevent rusting.

I know when I look in a tank and see the white Kreem liner, I think tick-tick-tick. It seems a shame to me to use it if not absolutely neccessary.   Mark.

agreed, I have heard of some real chipped up messes!

[coxy]

the last tank had to be lined due to pin holes and some other tanks that i have had chromed previously came back with chunky rust and crap which took some serious scrubbing. the liner that i used on the gtr tank came out a smooth zink  looking and extremely hard like plastic   

[rocketman]

 If its the silver Por-15 kit, It does give a better look inside the tank. Not so obvious as the white Kreem.  Mark.

the krem kit was $100 at any bike shop and i think for 40 liters seeing the gtr tank is 15 liters i got the kps kit for 20 liters and at half the price

 That's one more reason to keep clear of the Kreem, Coxy.  (I guess if you wouldn't put it in your tea, you shouldn't use it in your tank either!)  Mark.

All this talk of tank liners got me curious, so I did a little research. In particular, I wanted to know more about Por-15 as I'd already ruled out ever using Kreem. I ran across this thread that recommended a product named "Caswell".

Anybody here ever use it and how did it work out for you?

  Ive Seen A Lot Of Ways To Do This And Ill Give What Worked The Best For  Me    I Own A Auto Repair Shop And We Sell Batterys   We Return The Cores    I Saved The Acid Out Of Them In A Large Plastic Container   If I Want To Clean The Inside I Fill It Up   If I Want To Clean It All Over I Submurge It      It Works And Its Brand New Lookin     It Takes A Lot Of Batterys   But You Can Buy Acid  But Probley Not  Something You Want Around The Home     My 2 Sents    GENE

maybe the flaking is due to the tank has not been properly dried out i stuck mine in front of the jet fire and cooked it

[rocketman]

 I use an infrared heat lamp for stuff like that. It excites the molecules of the substrate and heats the item/panel from the inside out. Also great for painting parts when the humidity is making your paint blush. I used it recently to cook the moisture and fuel deposits out of the cracks in this fiberglass Bultaco tank. A real pain.  Mark.

 Better close up of tank damage. Extensive cracking and old repair damage.  Mark.

hey mark we have one of these at my work its about eight feet tall and has  four lamps and 2in of dust sitting on it it hasn't been used since 2009 when we turned a ingersollrand  roller into a volvo (painted it yellow) i think it has been used twice since new it seems a bit of a waist .

[rocketman]

 That happens quite often. I used to sell them. The one pictured is a small Infratech 1500W short wave. I don't ever like to HAVE to use it, but great to have when you NEED to use it. A lot of the body and paint techs were just not educated on what these lamps can do for their paycheck. They really speed things along if you want high production. Great for curing not only paint, but fillers, adhesives, etc. We had some problems with the medium wave units trying to bubble fillers and primers that had excessive film build. Again, an education issue. You wiil need it again one day and will be glad that its there!  Mark.

i found out that if the tank is lined it needs to be removed prior to chroming
