Answer: 
I would say no, the area where the corner should be is very rigid and may flex and pop the mud free around it causing more rework in the future

Answer: 
It will. It is a little thicker than the Butt-Tape so you might have fan your mud out a little more to cover up the joint.

Answer: 
Laminate composite. BY FAR. I have been doing drywall for over 30 years, and this tape is the best I have ever used. The "original" Straight-Flex is the best for sanding, but it is a little thicker than their other products. I use your basic fiberglass mesh tape on factory joints, and composite tape on butt joints and inside corners.

Given a choice, The Mesh! In application, they are pretty much identical... But the paper and paper composites are prone to fraying and pucker. The mesh, if mud application is scraped too hard, will have ripples, but they are something you can cover with a second coat of mud after the first coat has dried. With paper, you can get pucker years later. Either you live with it or you cut the pucker out with a utility knife and try to mud the hole. If you choose the paper, I recommend you make sure it is DAMP before you place it on the mud. During my first foray into mud-n-taping, we used paper. Someone told me to make sure it was damp before it was applied. I didn't do that and had to make many repairs to the puckers and bubbles that appeared later. The next time I used paper, I had a bucket of room temp water that I dipped the tape into. I would then pinch it with my fingers and pull it through to remove the lion's share of the water. This method worked much better, but years later, bubbles and puckers appeared again. Not as many, but still. We haven't really had any problems with the mesh! Your choice and good luck Read Less

Answer: 
Paper laminated composite is a better overall product. The memory-free hinge design allows for ease of installation, straighter corners, and perfect angles. The PUR-laminated nose ensures perfect corners without paper fuzz-up during finishing and sanding.

Answer: 
I wouldn't recommend it for 135 degree corners. I would use either Strait-Flex Original or Strait-Flex Medium. Those are a much better option then the Perfect 90. You can find them at most Home Depots.

2 in. x 100 ft. Perfect 90 Drywall Joint Tape Inside corners P-90-100 is rated 4.5 out of 5 by 36.

Seriously, you can't mess this up. I thought 9' ceilings would make taping the corners a challenge, but this product made it effortless and faster than I ever imagined. Really, this is as easy and time saving as you can possibly get. My first drywall project turned out great, it looks like a pro did the job. I have another room to drywall and I will use Perfect 90. I wish they made a bullnose outside trim tape also.

No more waiting for one side of the corner to dry or trying to get a perfect finish with a corner tool. Just put the mud in the corner, fold, cut and smooth. I sometimes get it to come out so smooth that I don't even need a second coat. You can paint right over it.
