Default Rust Prevention

So I've drilled and cut a bunch of holes in my car (snorkel fit).
Question is: what's the best/easiest/cheapest thing to do to the holes for rust prevention?
I was thinking of just using sikkaflex, as I'll be putting a heap of that around the holes anyway.

Or should I treat the metal with some rust prevention stuff first, if so (and remembering I'm a cheaparse and Jack's a rat) what?

All suggestions considered!

I usually will give it spray with anti-rust paint available from Bunnings.

That's the way I was thinking of going. Not sure how to do the bits inside the guard pretty tight in there. It's about 98% humidity here at the moment, not the best painting weather...

With the inner guard shield removed, or partially removed, just spray it up there and hope for the best

Galvanising paint. Then a top coat of enamel.

Sika themselves recommend pre-treatment of some sort.

The guard's not really a worry - bolt on, bolt off.

I'd be very concerned and careful with treatment if you've put mounting holes in your A-pillar.

after welding metal we use Zink spray , could be good too. i used antirust paint too or some other 3in1 that you can paint on rust no matter. they hold very good.
