I'm about ready to tear down and rebuild the front end of my
69 Chevelle Malibu. Before I start disassembly, first I want to degrease
the parts which have 30 years of tar, oil and dirt caked on them. What
is the best product to use? Are any of them safe for rubber parts
like hoses and bushings? A common spray-on product is called "Gunk" but
I have no experience with it nor do I know if it is the best at removing thick
greasy tar.
