tank sealant


Post by blewcrab » Tue Mar 05, 2019 2:57 pm

hey guys , my old tank was sealed before I bought the bike 9 years ago , and now it is coming off in sheets . It was a repop tank so I decided rather than trying to clean it out ,I would buy another repop tank . I really don't want to seal the new tank unless I am convinced by u guys to do so ….I would also like some good sugestions on what sealer to use if I decide to go that way. THANX !

Simple. Pressure test it with less than 8 psi and if it don't leak don't use sealer. If it does leak, fix it, and then it will not be there to cause a problem.....

I never use sealant, never. Do what the Rooperrito suggest, that stuff is for the birds, keep gas in the tank.

I agree with the others say about using sealants. Case in point, I bought a 45" many moons ago and the oil tank was coated with some kind of sealant. When the oil got hot, the sealant would start to come off and get stuck in the oil pump vanes and lose pressure.

Think twice about using tank sealers. It looked like a good idea when I did a tank in the 90's. Subsequently the stuff needed to be removed but getting it out was the stuff of nightmares. Even now it's probably only 99% removed and the remainder progressively comes through to the strainer in little bits.

When I was doing my WLA, I was considering using Kreem, tank sealant. to prevent the tank from rusting out, but was talked out of doing it.

What I did do was pressurize the tank, made sure that there was no leaks, and Parkerized the insides and as soon as dry, installed the tanks and put gas in it.

No problems yet...and even though the oil tank's got oil in it..........I did it to the oil tank too ... just for S.A.G.

I used something similar to this: https://www.duracoatfirearmfinishes.com ... 9614861641
