Idon't know jack #$@! about the other two compounds you mentioned I agree with Randy and Martin though fix what is bad (correctly) and do both sides (in and out). Herculiner is a great! product if you want the sweat equity, which most of us masochists signed on for the first time we drove an 02. The reason I brought up the Rhino lining is that you do the prep, you drop it off and they call you when it is done (not to mention they guarantee their work).
Good Luck
