I have read many posts but one in particular I cant find (I think the poster was Warlock) about adjusting the rubber stops to fix hood shake.

I know part of the process is to put something on your stops that will make a mark then close the hood, open it, and look to see if all the stops are touching the underside of hood.

What are some suggestions for using on the stops to do this? I think someone said lipstick was good but are there any other things I can use that would work? Also, where would I get them.

Thanks for all the help.
