Good Vinyl Seat Repair Product needed

[GMCPerson]

I received my new vinyl seat covers on Saturday and by Sunday evening, I had punctured two holes in the bottom of the seat. Warning, do not stack your seat bottom on the springs of the seat back - they are sharp!

I would like to try and fix the cuts. One is a V shape and each leg is about 3/8" long. The other is about 1/2" long and is fairly straight. There are a lot of different products on the market and I would like to know if anyone has used any them, which ones are good, which are not good, etc. Can you see the repairs after your are done?

The supplier offered to send me a new cover for $50.00 which is reasonable so I do not want to spend a lot of time or money fixing this one.

Thanks for your suggestions!
