    This isn't your typical post on here, but I figured if anyone knows about paint and paint products it would be here. I'm doing some modding to the truck, and I've really looked into taking other approaches but I'll have to painfully drill into a body panel. My plan is to put some self etching primer on the bare metal with a q tip, and once dry to use some Toyota touch up paint on it. I'll apply some fluid film to this area once a year as a precaution.

    I want my approach to be durable and not the source of rust and rot on the body. Any suggestions or recommendations on better methods or products are welcome!

    fluid film makes a sticker grease like product, that might be a better long term solution. but you have the right idea about painting the drilled hole, just be sure to let the paint cure as much as possible before installing a fastener.

    I was going to give the paint 1 day to dry, what's your recommendation?

    I think that is enough time, as long as it’s not really cold.

    if it's hot and sunny, one day might suffice. i overkill everything so i would either bake it or give it a week in warm/sunny weather. also if the hole won't be visible you could try a product like POR chassis coat black. I have used it in the past with great results and long term durability. It is what I plan to use on the bed when I drill the holes to mount bed stiffeners, followed by a healthy coat of fluid film.

    Personally, I'd prime and paint the way you described. Then I'd add a liberally applied flexible sealer (think RTV) to keep moisture away. After all of that. I'd consider Fluid Film or something similar. Living as I do in the Rust Belt, I can tell you just how deadly drilling a hole in a factory paint job can be.

    When I drilled into my sheet metal for hydraulic hood struts I used Rustoleum paint and it's held up fine for five years so far.

    Cold galvanizing paint. Let that dry then caulk in the fastener with polyurethane or butyl caulk.
