JSsuperbee,I hated doing the work,but the end result was well worth it.
I did leave what was still in good shape and freshened it up.The dry,chipped stuff I removed.
My car will be a driver so not many will crawl up under to see how well I do in judged/points shows.
At least I know in my mind there is no rot underneath..
Plus it's a C so I have more area to recover..LOL!
