Hi Folks.
At the moment i have a flat/matt black tank. I did it with $3 spraycans. Everytime i put fuel into the tank I drip some on the paint and it marks the paint. The cool thing about matt black is that I can just spray the tank after every ride. I will soon get sick of this though.
Does anyone out there know of any matt or saturn black paint I can use that wears a little better with fuel drops/drips/runs.?

Hi Paul, I think it melts because it is cheap acrylic, which petrol will mark. The best paint would be 2 pack, but you can't get this in a can! Why not pay a few more dollars and get something like VHT flat black which advertises as having some chemical resistance and comes in a can: www.speco.com.au/vht_engine.html#enamelsRegards Phillip |

Enamels in general will exhibit solvent resistance (heat cure) if subjected to elevated temperature still within their range. This is typically 212F/100C x 1 hour. The VHT is a engine/header paint that cures in place with operating temperature. The thought of baking a fuel tank is somewhat scary even for me. A two part catalytic clear coat is available from your local automotive paint supply store. I bet they will work with you to get a matte finish. You will need a compressor and touch up gun. PC |

So PC, your saying that the air dried VHT would not provide ANY increased chemical resistance at all over a cheap $3 paint? I think its a lot cheaper than buying a compressor, spray gun etc to spray 2 pack  |

I am not saying to stick you fuel tank into an oven to cure the paint, but I have never had any worries with the VHT flat and satin black paints that I do my TT and XT500 engines with being affected by petrol, after the parts have been baked in an oven for a few hours at 100 degrees C.
If you choose too drain the fuel and any fuel residue from you tank and gave it a good flushing prior to painting it with a VHT pessure pack, then baked the paint by some means, like using a couple of heat lamps either side of the tank for a few hours, it woud probably give you a finish that was reasonable resistant to the odd fuel splash when filling up.

Specific to enamels and 1 part piants...Yes, that is what I am saying. You can test this by painting a sample, keep it at room temperature for a few days and then wiping with a cloth moistened with a low vapor pressure solvent of your choice (petrol will work). If you are using a lacquer then no... Enamel's in general offer greater solvent resistant. For your bike, you may well be able to sun bake your black enamel for a few days. Enamels cure with heat and time. Less heat more time still works. I do not know the specific threshold temperature, but I will guess 120F+ would be enough. PC |
