I have an old jerry can that has rust inside of it. What can I use to paint over it that is safe with gas and wont deteriorate?
thanks |

1st remove as much of the rust as you can. Put some chain, steel nuts and bolts in it and shake it or do like I did leave it in the back of the truck for several weeks so that the metal will work off some of the rust. Rinse with something that will no leave a residue. 2nd get a motorcycle gas tank painting kit. Use that to paint the inside of the can. YMMV |

I have seen the followng advise shared elseshere (from my thumb drive) 1. Get a pint to quart quantity of nuts and bolts (these will help work loose rust and flakings free) 2. Go to pool supply and buy Murric Acid concentrate and prapare to directions 3. Add Acid and nuts/bolts to can and close it 4. Shake and stir for a couple days 5. Remove the ingredients, wash with soapy water several times, rinse with clean water, and dry completely 6. Coat the inside of the tank with coating of your choice Honestly, I have not had to do a can yet as none of my cans were rusty - I saved the advise as I would be glad to buy some rusty cans if I could find them at a good price. |
| I've used vinegar in an old motorcycle gas tank to remove rust and it works great. Youtube has several videos about it, I saw one by beast1201 and he tried various known methods to remove rust. The apple cider vinegar worked the best. You can even cut the vinegar with water and it will work, if you don't want to buy 5 gallons of vinegar. Wally world has vinegar for about 2.50 per gallon last time I did it. Just fill it to the top and give it 2-3 days. It will remove everything. I put an entire tank in a tub and filled it to the top, 3 days later the paint was peeling off. |
| Clean some pea gravel and toss it in the tank with some diesel. Get your kids or someone besides yourself to shake the can for a while. The gravel will Polish the inside and remove every bit of rust. Afterwards rinse out with a garden hose and always fill the tank to the top for long term storage. |
