Tailgate holes, how to prevent rust?

Hi, I just bought a 2020 Tundra, I ended up (stupidly) drilling holes to mount a led backup bar, the plastic brackets that were supposed to hold the bar in place broke and it seems the tape holds it just fine....

I drilled about 12 1/8th holes through the bottom of the tailgate mount. Should I go out and buy filler. Go out and buy a touchup pen or do both and apply? Will this stop rust? Any advice would be great.. This is my first tundra, thanks..

Welcome from NY.

Can you post some pictures so we can see it?

 

My routine: Clean the hole well so there are no rough edges. Paint with rust paint at least two coats. Fill in with RTV silicone if it’s not easily visible.

 

Sure, here you go. The LED bar in the picture blew a fuse, its supposed to be plug and play, but I guess not. Dealership was nice enough to replace my fuse no charge, even though it was caused by an aftermarket.

Sure,

 

Do what @mountainpete said in post #3.

Or since it's white you can get that Flex Seal rape in white and cut it to the exact size then cover it with the lightbar.

 

smear a little axle grease in the holes yearly

 

Ditto!

 

I will do this, Thank you!
