I have an R60/2 with original paint and pinstripes in pretty good condition. However, the inside of the tank not only has sludge from gas that sat in there for who knows how long, but the original red liner is bubbling and peeling off. I know there are places where I could send it that would do a complete repair involving removing all the paint and cutting the tank open to replace the liner, but would I would rather do, if possible, is find someone or a shop who has the experience to clean the tank and re-line it without removing or damaging the original paint on the exterior of the tank. If anyone has any suggestions, please send them my way. I know of POR-15 and that may be the right approach, but this is not something I want to do myself - I want to send it off and get it back ready to go. Thanks!
