I would use the products offered by SEM myself. So you can call them and actually talk to the company that made the product and get it to work for you instead of you buying something you might not be able to get answers to your questions .
JUST MAKE SURE you do not wipe the raw urethane with a STRONG solvent...that is a BIG NO-NO.

Not knowing where you live due to you did not provide any general Public Profile information...so......I cannot say if you can buy the SEM products locally or not and get them to provide you with an application gun if needed.

urethane bumper repairs are more for Camrys and Accords. if it isn't flapping in the breeze it is good enough. and the bumper is not 40 years old and gonna tear or ripple right next to the repair. it is a stopgap. as long as you are aware of this, fine.

NOT knowing the year model of Corvette we are referring to.
I do agree...that depending on what type of urethane bumper you have on your car. A repair may NOT be possible. Due to the 1973 and 1974 urethane bumpers were made out the black urethane. Which in time...they got really brittle and can crack and shatter.
If your urethane bumper is a creamy yellow color. Than it more than likely can be repaired but it may not be easy due to it flexing when you are sanding on it. So it does take time.
It also has a lot to do with where the crack or damage is ....in regards to if the urethane will flex a lot or not.

Pair of needle nose pliers and a heat gun and you can get that a lot straighter and the rip near closed. You might want to pull bumper and try a clothes iron on the back side to get it flatter. Be careful with temp. Then bond somethingsacross the back of the tear. That near the lip it may be sturdy enough to sand out well after filling.

This damage is repairable but it also depends on how much time and effort you want to put into it versus putting on a new bumper cover.
SEM sells the reinforcement tape that can be applied on the backslide to make this areas super strong....along with the other types of adhesives and fillers to get it right.
I agree with Derek...using a heat gun to relax the pushed back area and get it back top where it needs to be then get it filled in is what is needed.
I know I would have to remove the bumper cover to fix it. And to be honest.....because my perspective is quite different due to I have to charge for this type of repair. I would install a new one instead of taking the time to fix it even though I could fix it. The end cost would be about the same if not more due to having to deal with the paint job on it and where I would need to strip it to so when I painted it...it looked good. It CAN be repaired...but how much time you choose to put into it is up to
you
If you do choose to fix this...call SEM and get the tech line guys to get on Corvette Forum and look at your photo. (1-800-831-1122) OR while the phone you can send them an e-mail with a link to your thread. That way you will be able to get all you need to fix this.
