Ok, so today I took "G&R's 57 GMC"'s suggestion in post #384 above, stopped at the local bicycle shop to ask for an inner tube out of their trash. They said, "Take as many as you want!" I only took one and did THIS with it:
Yeah, kind of meh.... But the ones the shops sell don't look much different. It is what it is I suppose.
I also finally got my Craigslist-find front bumper painted on the reverse side and mounted. Thereby finishing the recent front end work:
Hell of an improvement to me.
In preparation for installing door weatherstripping, tomorrow I clean out the door interiors (loaded with crap), Ospho overnight then paint with KBS...maybe Rust Reformer; depends how bad it looks after treatment.
