Need fast help with rubrails.

I purchased the rigid rubrails from here:

I am having a heck of a time figuring out how to install it. Problem is the plastic is so tightly coiled that it takes alot of force to straighten it out, I doubt the #8 screws speced for this rail will hold it in place as I can barely get it straight. I only have today to get it done. I tried letting it sit on the hot driveway for an hour and it did nothing, I tried a hair dryer which was hot enough to burn my hand, but made virtually no difference to the rail. I bought this type of rail to save some cash over a taco kit, I hope someone has a good solution that will solve my buyers remorse. Please help as I only have till this afternoon to do this.

 

I have it sitting in the garden tub now with hot water. Hopefully it will make it pliable enough to work with.

 

I got the water up to almost 200 degrees and let it soak for 20 minutes while maintaining the temp. It did NOTHING! Finally the wife and I decided to just muscle it, what a PITA! I would not recommend this product in the future!

 

It was a pain, I tried stretching it from my jeep to the garage, let it set in the sun for a bit, then when I went to unhook it......THWAPOW!....shot back like a dang slingshot, lol. I'm just gonna deadend them on the back for now, later on when I'm doing touch ups I will see about making some end caps or something.
