Thanks for posting! I knew you were wanting to do it, and I was waiting to hear your experience. I can imagine how stiff that rubber was to try to get under!!!
So, when I do mine, I'll need to find a helper, huh! My other half isn't near as limber as I am, lol.
Oh yeah for sure, a helper is a must. I would suggest of course watching some you tube vids also. And set aside a whole weekend not just half a day like I did.
