I have a brick entry that's buried under 2 layers of sheet vinyl. The
sheet vinyl peals up very easily -- it was probably adhesive backed. But
it leaves its backing paper and glue behind on the brick. The brick is
some kind of non-porous type that has some kind of glaze or sealer. Am I
going to damage the surface if I use a manual scrapper? What's the
alternative, heat gun and/or goof-off?

The heat gun might get you there,marks that are left might just come
off with brick cleaner
[acid] in old money,it's called FEB CLEAN now it's worth a try.
ps/ follow the ACID and WATER ratios on the container,sometimes it
looks like nothing
is happening give it time.Twenty to Thirty mins normally,if there is no
sign of progress
then up the dose not before.
