Hey guys,
Was wondering if anyone has run into this: Brick substrate (vertical), with residual "liquid nails" and rubber epoxy from previous signage. This is a commercial property and you can see from the picture they put up new letters (signage) over the old glue and adhesive and NOW they want to remove what’s kinda in between the new letters. Signage appears to be a stainless steel. I have tried goof off (not strong enough) and Eacochem’s Acrylicstrip (worked ok on the clear glue or caulk, turned it semi-gelatinous and I was able to scrap off) however liquid nails or colored glue remains.

I’m thinking of some sort of paste, i dunno, thoughts?
