powder coating

[motorhed65]

I just bought a new gas tank for my 65 chevy. the old one was all rusted and had holes in it. I want my new tank to last for years as i plan to keep this car for a long time. I was wondering what the benefits of powder coating are, does it protect against rust? Also i was wondering if the new gas tank can withstand the heat when the powder is being baked on. I only want to coat the outside of the tank. I also looked into por 15. Which one is better to preserve my tank and fight rust? Price is not a concern, i only want to do the job correctly. Thanks.

Powder coating is applied electrostatically to a DEGREASED surface. Then, it is "melted" at about 325 degrees. Oil or grease will outgas and produce bubbles. This also happens when you have hollow tubing that has oil on the inside. The oil vaporizes and escapes thru pinholes in the welds. We degrease all our frame tube material before we weld it.

You tank must be new.....obviously. You cant have any rubber or materials that wont take the temperature.....obviously. They have to hang the tank to coat it and to put it in the oven. Where the tank touches the hangers, there will be no coating.

Powder coating is tough but if you get a nick thru the coating, rust can form....just like any paint.

Outside of exterior coatings,,if you store your car for long periods of time,,it's a toss up between safety storage and rust prevention,,,if you keep the tank almost full when storing,,then you'll never have to deal with rust in the tank,,,the problem is.....who wants a full tank of gas in their car when it's stored for a long time indoors???
Personaly i wouldn't powdercoat the tank,,,you'd be letting yourself in for a whole bunch of seam sealing problems,,,use a good rust proof undercoat instead,,,you can also have the inside of your tank coated with a sealant compound.

I have no reservations about powder coating an old gas tank. Take it to a radiator shop and have it boiled out. Silver solder any pin holes. The radiator shop can do this for you. Then have it sand blasted and coated. The coater can usually do the sand blasting. Finally, get an Eastwood gas tank sealing kit. This is a coating that you put into the tank and slosh around real good. It fills small holes and puts a rust resistant coating on the interior.

Bibs, one of the local parts stores used to sell a two part coating for inside a tank, a neutralizer and then the coating. I was told it is no longer available. Is this the type you use?? Sure would like to find a source for it again, it was really good stuff.

Powder coating is really strong and good but would cost too much and not worth it for a gas tank. What Bob said is the best choice in my oppinion.

I had a tank coated with that pickup bed line spray like Rhino Coat.

Works great and looks good!

Only thing I hear about those sealers is that they start to erode and get into your gas after a few years and just breaks up.... Not sure if it's true but heard it from a lot of people. They say it takes a few years though so who knows.
