Fuel tanks can be tricky to refurbish - not the exterior but the interior. When heavy or even light rust is present the machine will be forever plagued with poor running due to a blocked fuel tap and particles of contaminates working through to the throttle body and injectors - a frustrating problem to deal with.
When the rare opportunity comes along to renew the tank you would be wise to take it.
