I know the product, but not the asked for name. I do not believe that home centers carry the stuff. A freind of mine has used it when doing many moutons on french doors and stated that it does work, but the clean up is worse than the attempt to keep it off in the first place.
I have heard that spray pam works too, never tried it.
If you fall back on using the tape method, be sure and get the blue Painters Tape. It leaves no residue and will not stick like masking tape does.
If you find the name of that product, come back on and tell us.
