   I've used some and while I'm not the biggest fan, I think it seems to work fine. Try a third coat (something I almost always do) and see if the perforations don't go away. If you still see them after the third coat and sanding , but can't feel them they probably won't show up thru paint.

   It's too late for this job, but I've been using spray on adhesive (Super 77) to attach vinyl corner bead. This cuts down on the number of screw I use, and this is a gripe of mine, the metal is "less likely" to pucker when screwed on.

   One thing I do like about the vinyl is they are really expanding the profiles for corners. I'm installing some curved half walls and I can get a vinyl bead that will wrap around no problem, no cutting.

   One question, Has anyone used those new prefinished, no mudding corners? I've used them on small jobs I did not want to go back to again and again to mud. I have not quite mastered them and they are quite expensive($0.50/foot). I use them one small commercial jobs where I can't make money waiting for mud to dry. When used with a 45 minute Easy Sand setting mud compound you can knock a lot of down time out, but I'm still skeptical.

   *I have seen one of the above mentioned products in a magazine somewhere, maybe in FHB. I would love to know how well they really work. I am always a bit leary of those "new revolutionary" products.Sceptically,Pete Draganic

   Ted,

   I use vinyl corners all the time. The telegraphing of the perforations is probably due to unequal shrinkage in the mud (the mud is thicker - and shrinks more - over the holes than over the vinyl. I avoid this by using a setting-type compound on the first coat. I have always done this on corner bead (whether metal or vinyl), mainly to avoid the extra dying time, but also because fast-set is a little stronger than regular compound.

   Regarding the buckling that J.D. refers to: This can be avoided by using nails rather than screws. Some people use narrow-crown staples in conjunction with spray adhesive, but getting the staples to set consistently to the proper depth (without going right through the vinyl) is very important.

   I'm strickly a metal stud guy so the nails are out. There are times I long for a hammer and a nail pouch. Could just be looking for an excuse to own one of those neat drywall hammers. They feel great in my hand and seem to have nice balance.
