Exclamation DIY: Red Kote. Breathe new life to your rusty gas tank!

I researched fuel tank liners and decided Red Kote had the best reviews out of them all. In the past, I paid to have my tank lined by the local radiator shop, but this time and bike I decided to do it myself after reading numerous DIY rusty tank articles. Surprisingly, O'Reilly auto parts carries Red Kote in stock!

I forgot to take pictures except for the finished project. WEAR PROPER SAFETY GLOVES, GOGGLES, AND RESPIRATOR.

Step one: Determine if your tank is rusty.
Step two: Remove the petcock and filter screen.
Step three: plastic off the tank to keep the paint from being
damaged. I used a heavy garbage bag and duct tape.
Step four: Plug tank drain and fill with a pint of CLR/water mix.
Step five: Determine that little rust is removed and proceed to
a "bigger hammer!" Use a long handled "ball" style toilet
cleaning brush and FULL concentration CLR in the tank.
Step six: lightly scrub the inside of the tank. The rust will wipe off
easily. Quickly fill with water to dilute the solution after
rust had been brushed off all surfaces.
Step seven: Wash out inside of tank with denatured alcohol and
blow COMPLETELY DRY with compressed air.
Step eight: Fill tank with half a quart of Red Kote and roll tank in all
directions making sure to get complete coverage of all
inside surfaces evenly. Pour out excess liquid and air
dry. Finish assembly of parts and tank onto motorcycle.

Here's the finished picture of the inside:

P.S. No, this is not on my avatar bike...

Ok, I forgot one part.
Do this in warm weather! It is an 8 hour dry time in 65-75 degree weather (I called and talked to the chemist). I did not do this project in warm weather and called them to find out how to speed up the dry time. There is really no easy way because 1) it stinks while applying and drying, 2) it is highly flammable.

I'm going to see how long it takes in this 50 WA weather...

I've used POR-15 successfully in the past and the steps are almost identical. It's not difficult to do, but it takes a lot of time, preparation and fairly messy as well. Your end result looks great.

I used this on my TW-200 tank about 5 years ago, I love it!! Way better than POR or CREEM products IMHO which I used many times in years past. This is a pretty simple process and cheap and has held up like a dream. I paid 15 bucks for a quart, used about 1/4 of it, and traded it on down the line for welding work. Very economical.

Cant remember the ambient air temps when I did it, but it took over 24 hours before it quit smelling or feeling tacky, so plan on 48 just to be sure unless you live in Arizona

Vinegar. Fill it with vinegar and let it sit. It's cheap and super effective.

I read that too. CLR was done in ten minutes. The potions are endless: vinegar, vinegar and sand, water and sand, water and a chain, water and bb's, water and muriatic acid, electrolysis using a suspended piece of steel and a battery charger, etc.
I don't know the time on using vinegar (?) but I didn't want to wait around.

Till you drain the vinegar only for it to flash rust in matter of seconds and eats through your gas cap.

<slaps forehead> yeah I was thinking about using vinegar but wouldn't mind paying a couple extra bucks for a more thorough cleaning that CLR would probably provide - and yeah time is money!!

oh yeah, when I coated my tank I remember how convenient it was being in hot FL to do it!

Water and baking soda for electrolysis. Instead of steel use a piece of carbon arrow shaft. Plus (must be DC) on shaft. Battery charger or power supply. Let it work until when you pour it out to check it the tank looks clean. Reuse the water.Took mine 6-8 hours.
Rinse with water. Drain and blow dry. Install inline filter. Don't use ethanol fuel.
Did a KE100 tank last year that was VERY bad. It came out shiny steel inside. Did not coat with anything else as it was not leaking.

Curious to know how this holds up. I know CREEM is junk. Heard mixed reviews about Red Kote. Tend to stick with POR 15.

Seriously considering coating the vintage fiberglass tank with KBS. Caswell has mixed reviews from what I've been reading.
