Chrome body molding replacement 1987 Suburban

[Nodnarb76]

I am looking to replace the chrome body molding that runs all the way around my Suburban. I had been looking at the molding LMC truck sells that is already pre-cut for $149 as I didn't want to take a chance of damaging the molding trying to cut it to fit.

However I have found a roll of the same molding on ebay for about $45 shipped. In order to save $100 I wouldn't mind trying to cut to fit. What do I use to cut the molding so the ends aren't damaged?
