Gas Tank Sealer

by Tony
(United States)

I have a new steel, two piece gas tank for my latest project and was wanting your input on gas tank "sealers". I know there is a debate out there on whether or not to use a sealer in that some people claim they crack and chip and become more of a hazard than not sealing. What are your thoughts? If you do recommend sealing a gas tank prior to paint, what brand to you use/recommend?

Thanks.

I've used POR-15
by: Anonymous

To start my bike build I decided to find a "donor" bike.(a reasonably priced used bike on craig's list) I'm gettin a bit older (but just as wild :)and found a 84-99 softail with alot of good usable parts. I took my tins to my painter and asked for his thoughts on the condition of the insides, (3.5gal.Fat-Bob FXST tanks) and what my options were. He mentioned POR-15, and I found it on the net. I ordered the "Heavy Duty Motorcycle Tank Repair Kit" I followed the directions as stated. Though it was alot of work, I caught a good buzz. (I suggest good ventilation) My tanks look like new agaqin, and my buzz is gone :( Just like my senior year in High School. Geezzz,.. In 1977 High School was HIGH School, and a lid was cheap!

The best sealer
by: rider75

The two "big" names in fuel tank sealers are Kreme and POR15. The POR15 product is hands down the superior product. Follow the steps exactly and you will have a tough, thin, chemically bonded coating that resembles a dipped plastic coating. I've used Kreme on an old Honda and Suzuki tanks and both had to be redone within 3 years. The POR15 in my BMW R75/5 tank was done 5 years ago and still looks like it did when fresh.

piece of mind
by: chappo

I would TIG it or braise it for piece of mind and your safety as sometimes a sealer will break down over time,it would be allot of time and effort to repair after you have had the tank sprayed.
