Fixing a rusty tank

[jeepred]

My metal tank is rusty - surprise!

I have a 185 and I want to get rid of the rust in the tank. It really isn't too bad, but I just don't want it clogging filters or getting in the engine. I know that you put bb's or nuts and bolts in the tank to clean out the tank, but my question has to to with what to do after this. I have read you only need to use a sealer like Kreem if you have leaks. Since I have no leaks can I just keep the tank full so it wont rust again? It is winter here and I have heard horror stories about how long Kreem takes to dry in the cold and I would rather save the money anyways.

Thoughts? experience?

you can clean it out with muratic acid.

DO NOT use Kreem. I've heard plenty of horror stories about that stuff not working. Get one of these and never worry about it again: http://www.por15.com/CYCLE-TANK-REPA...ductinfo/CTRK/

i think people use red kote now

So after cleaning out the inside keeping it full of gas wont keep it from rusting, you have to use a coating?

its a good time to do it ... the tank is clean and off the bike ... so why not cote it ?

You can get a POR-15 kit off eBay. That is what I did with my 200x. It even sealed up little pin holes around the petcock. It has had gas in it now for about 6 months with no leaks.

I like the por15 tank kits... Did my BR and my 350X that way... Very nice product... Stripped a kreem coat out of my BR to redo it with por15...

Don't use full strength muratic acid,dillute it with water.Rinse the tank out really well with water.Then take some dish soap to it and dry when done.Don't know how bad the rust in your tank is or the condition of your paint on the tank.If the paint is nice be very careful not to get any acid on it.I usually use Acetone and drywall screws.I also have a old dryer rigged up to tumble tanks in.The heating elements are remove and there is a shelf inside to strap the tank in.I still rinse out with soapy water and dry it.Then I seal it with Casewell tank sealer.Works really well if you follow the directions and remove all loose rust.Even if you don't get it all out it will seal it over.This stuff will plug big holes.What ever you do don't use the Kreem.

if its just a light rust film than clean with gas and bb's or nuts. Fill with gas and your done! if your tank has no heavy flaking rust or holes DO NOT SEAL IT!!

buy a litre of evapo rust, let it sit, rotate, when completly bare metal drain the evapo rust and fill immediatley with gas worked for me i can get pics if needed

Hey guys, dumb question but you put gas in there while you shake the bb's. screws. nuts etc around.... isnt that a bad idea? Or do you do it when its dry inside?

Another vote for POR-15. 8 years strong on my '86 Concours tank which had a couple 2mm sized holes in it! Good stuff. Drys to a grindable finish... unlike Kreem.

Oh yeah.. Kreem eventually flakes/peels off.... I have a '78 KZ400 tank that needs the peeling Kreem crap stripped out of it before I can use it again. Bad karma.

That is funny that every body is bad mouthing that tank kreem cause I did my 70 tank a couple of months ago and I was checking the gas in it last night and found it had started pealed . So pealed all of it out I could and I hope the rest of it don't come lose cause I don't want to acid it out cause I just had the tank painted
