fine-sddBy mistake, I applied a medium strength 3M Painters Blue Tape
on a fine-paper wallpaper in order to protect it while I painted the
crown moulding. As a result, when I began to remove the blue tape, it
took a couple of patches of wallpaper off the wall.

I was eventually able to get the tape off using a heat gun on low.
While getting the hang of heat/speed, I bubbled/blistered a 2 inch by
1/4 inch wide patch of new moulding paint with the heat gun.

My questions a

1. What brand/type masking tape can I use on fine-paper wallpaper to
avoid pulling off the top layer of paper when removing the tape?

2. How can I fix the edges of the paint blister and finish it so it'
looks better?

TIA for any tips, suggestions, and comments.
