This is a 'passing the time' kinda post. I've been looking at the coolant pipes on my 2 40s (not restored but needing it) and wonder is there an ideal type of oil I can just brush/spray on there to keep them supple. Is Linseed Oil the trick here? I sprayed diesel on them and the clips about a month back but thats just dried right up and doesnt look like it was a good idea at all now. I have no leaks nor problems, I just want things to stay young and supple like my bones (used to be)!!!
