I really appreciate the words of encouragement and it means even more coming from someone bold enough to go by 'queefchief'!
I got the rear seats mostly stripped and didn't find any nasty surprises. The crannies and nooks will have to wait for sand blasting. I have a tiny Harbor Freight one, but I'm not sure it'll be worth it to use that on so many areas with thick sound deadening and rock guard. I'll wait to see whether I engage a professional or buy a bigger blaster.
Next will be underside of seats and engine bay.
