I have been using WD-40 Specialist White Lithium Grease on my convertible top's mechanism. I don't want to get the lube on the top and I spray it into a small container and then apply it with an artist's brush to each joint. I let the joints soak in the foamy lube for a while, then I open and close the top a couple of times, then I wipe the excess grease off the joints. It's a bit tedious and messy. I can't reach all the joints easily and I am looking for a better way of applying the lube. Suggestions, please?
