1 gallon tank and paint

Hello, I purchased a 1 gallon tank but it looked like cr ap when I got it. So... I repainted it flat black and liked the way it looked. Problem....when I fueled it after 2 days of drying the gas started eating the paint. Was I spose to hard coat it ? I don't have access the the machine shop I used to. What coating do they use on the original stock 2.5 gas tank that came with the kit ? Thanks
P.S. will the smoke alarm go off if I bake the painted tank in my house oven say.....on 150 degrees ?

Don't bake it in your household oven- the chemicals will linger, get into your food and posion you.

Especially if you've already put gas in it!

Most spray paints have to cure for a few days before they really are dry and will resist gas.

If you have a hobby shop around get some fuel proof flat black paint. If it'll hold up to alcohol and nitro it'll hold up to gas and 2 cycle oil.

BTW, if you have a garage and 220 going to it an old electric stove works great to bake powder coat.

Tanks a lot ! 220 ? how hot ?

That's interesting regarding the old electric stove. I'm picturing building something larger say out of firebrick... a kind of oven/kiln large enough to fit in a bicycle frame suspended by wire from the four corners of the oven... use the heating element and controls from the original stove. Would that work, do you think? Powder coat sure is nice.

From what I've found online the parts need to bake @ 450º for 20 minutes.

Harbor Freight sells this unit that needs a compressor for $69

- Harbor Freight Tools - Quality Tools at the Lowest Prices

Harbor Freight also sells the powder coating.

And I found this self contained system for $139

There is a LOT of useful information on that site too.

If you want to bake spray paint in an oven, 150F is fine. Do not go over that by too much though.
I would leave the part in for at least 1/2 hour to 45 minuits. I have done it many times in the past with excellent results. No I did not ust the oven in my kitchen! That really is asking for health problems.
I have never tested a part for gasoline resistance, however I have read that appliance epoxy paint holds up well.

If you want to just cure paint on small parts a toaster oven will work. Check yard sales or thrift shops. Everyone seems to have a toaster oven they don't want. lol

I didn't bake my tank, guess I need to check out Goodwill for a toaster oven. I did find that Krylon Clear Triple Glaze seems to work. although I spilled some gas on the tank on day after I painted the tank and that caused an issue, since then the glaze appears to be holding up.

I have an old charbroil barbque and I think I might try that as an oven.

A barbeque will also work as an oven. Set a cookie sheet on the grill between the burner rocks and the bottom of the part too be cooked. Do not let the part set directly on the cookie sheet though. Suspend the part if possible, using coat hangers or really stiff wire to make a jig. Put the whole thing in the barbeque and cook slowly on low heat, checking often untill well done.
Never, ever use the barbeque for cooking food afterwards, ever!!!
