Antenna Mounting Help

[Mopar Crazy]

I put a new AMD fender on my 68 Charger. It's about that time to drill the hole for the front antenna.
I have the correct location but I'm Leary about drilling into a new painted fender.
Any advice as to what type of bit or stepdown bit to use, and the best way to prep.

Thank you

Put a few layers of painters tape on the area to be drilled. Use a small starter bit and move up in size until it fits a step drill bit. Use cutting oil to keep it cool, and take your time. Dont push down. Let the bit do the work. When done, use a small file to debur the edges, clean it with acetone, and put some paint on the edges.
The fender is thin enough to ise either titanium or high carbon bits. I have both from HF and they work fine.

Why don't you look into a hidden antenna, then you won't have to drill any holes. Cleaner look.

Thanks to Dino and Will for the replies.

Don't spill any Acetone on any painted surfaces as this may remove paint.
