Drilling a powdercoated frame?

[JVictor75]

I just picked up a freshly powder coated frame and am seriously contemplating picking up the No Limit bolt on rack and pinion.

There are a couple of other areas on the frame that I will need to grind/drill (where the front sway bar mounts go, for instance). <Edit: I bought the frame after it had been coated.>

My questions are as follows:

1. How badly am I going to screw up the powder by drilling thru it? Is this a case of just not doing it at all because it'll all just crack and peel off and end up looking like utter crap? Or if I'm careful will I be okay? (maybe)

2. How difficult/easy/expensive will it be to powdercoat things to match (silver vein with a coat of gloss clear over top)? I have BBC frame towers, shock mount re-locators front and rear, a tubular trans mount crossmember, etc.
