I remember using the original monocoat, the stuff before super monocoat came out. It was the toughest thing to apply. It was sticky, just like the trim strips. this was back in 66 or 67. gawd, that's old.
I also remember us thinking that "oh Boy, we don't have to sand anymore"----NOT!!
The covering look awful. Had to strip it off and sand. We asked "why bother with the covering", we still have to prep the surface.. Ol well, we lived & learned.
