Drilling, already painted panels

[Salvatore]

Maybe want to use a piece of masking tape over the area you want to drill, and then mark your hole. Also a smaller pilot bit first will be easier to line up the bigger, final hole. Lay some rags or towels under the hood to catch the filings and maybe a piece of wood to support the hood while you are drilling while you have it slightly open. You will be able to press on a firmer surface to drill straighter and your bit will end up in the wood instead of any other part of your car.
