Will it seal a PVC pipe that has a 1 inch slit? Must hold 75lbs of water press. Would put a rubber patch & 2 pipe clamps over it.

"cut out the pipe and replace the pvc." By doing that, you are creating at least two new joints that may leak.

Is this product good for the broken plastic frame of eyeglasses? The eyeglasses is broken on the temple leg.

As an optician for over 30 years, sadly, nothing I've found short of a 2 part epoxy/resin will work...but only .temporarily. plus you'll probably get it everywhere including the lenses. I suggest visiting your local optician. I have tons of discontinued frames and can usually hand-edge the lenses if its a close fit . BTW, its the same with so-called scratch removers for eyeglass lenses:snake oil. hope this helps... John shameless plug follows: glassescontacts.com or FB.

Can it be used more than once, or is thrown away after one use?

Yes, it can be used more than once. I bought a tube from Amazon on January 2018 and used about half of it then. In February 2021, I used part of the remainder to fill in some drill holes in some wood furniture that I was repairing. So for me, I got a 3-year shelf life out of it. The trick to keeping it fresh is to keep the outer foil on the remaining amount (only cut off what you need to use), wrap the whole thing in plastic wrap, and then put it back in the plastic tube and secure the cap.

Will it fill in gaps? Have some plastic planters that have a few cracks at the top edge, The cracks are about 3" and a few small gaps

Yes, if you mold it to the shape of the existing surface correctly.

great product

I buy this product often and find it very useful for many diy jobs. I use disposable gloves when handling it. It is good and strong, holds well. good value for £6.99. It does set quickly. I like leave for a day or so if using with a wet surface.
