Grease? Oil will wash off with the right solution, grease will too but the work involved! Better off spraying oil! I cant image the time he spent doing that! lol
When I took my 73 out of storage, were it sat for 20 years, anywhere there was oil it cleaned up and looked new. Everywhere else was rusty. Thats when I learned that oil protects. A friend of mine restores old cars and he prefers the dirtiest, oiliest ones he can find for parts.
Sorta puts ya between a rock and a hard place. Perfectly clean and prone to rust or oily and dirty yet easily restorable?
