I have been limping along with the original tank on my 74 Eldo for a long time now. I did a complete mechanical restoration a number of years ago, leaving the original paint intact. The tank had the perfect patina, but had scores of pinholes on the bottom of the tank and along the seam like so many have nowadays. I sealed the pinholes with an aerospace grade brush on sealer, and then a couple of treatments with POR-15, but knew it wouldn't hold up forever.
Good rust free Eldo tanks are becoming quite rare and go for big dollars now days. I was lucky to find a rust free tank with patina to perfection for my bike on Ebay. I believe I won the auction for a much lower price than what I have seen others go for because it had a dent.
I took the tank to the local paint-less dent guy who has done lots of great work on Harley tanks. He wouldn't touch it because the sheet-metal gauge was too heavy in his opinion. Harley tanks use a lighter gauge and easier to work with as he told me.
So I went into a 3 year or more holding pattern until I saw an advertisement in The Antique Motorcycle, the mag of the Antique Motorcycle Club of America. The ad was from Dent Dynamics in Santa Rosa, CA
https://motopdr.com I took a leap of faith and shipped the tank out to them and received it back today. I am very impressed with the results! I can't say the repair is completely invisible but due to the difficulty of the dent I wasn't expecting perfection. But I must say my expectations were exceeded. I can recommend them without reservation.
I can now ride the Eldo without worrying that it will catch on fire!
