Funny this subject came up.
Let me just say that while poking around underneath my new L78 Camaro I found that there was paint screwed up on the subframe. Looked like someone applied paint stripper to it. I popped the hood to discover that the master cylinder was leaking like crazy. It proceeded to drip all over the subframe rail and a-arm ruining all the paint. Having to take everything apart in fear of spilling more was like dismantling a bomb. I have been doing clean up and repairs all week.
