Re: Just an Idea
It's also a very good idea to use a pneumatic body panel saw. They run at higher RPMs and further reduce the chance of a warped / dimpled body panel. If you can't borrow one, Harbor Freight sells them every day for about $35 and I read recently where they sometimes have them on sale for $20.
Once you have your positions laid out, cover the area with duct tape and re-draw your lines on it. Don't use masking tape- the reason for duct tape is it's thickness which provides a wee bit of cushion and also holds on to the metallic dust you'll be making and keeps it from scratching your paint beneath.
After your cut is made, be sure to paint the newly exposed metal and allow the paint to dry thoroughly before putting your vents in.
I did all this when I mounted LEDs in my TJ, and it went swell.
