What do I use to prevent rust after drilling holes in D4. It’s for a ladder mod.

I’m attaching the Terraforma ladder to the D4. Need to drill existing holes to make them bigger for kit supplied bolts. What can I coat the holes with to prevent rust. Thanks

You could use Jenolite or a similar rust proofing product, followed by a bit of red oxide when the stuff has gone off.

But if the holes will be under the ladder when installation is complete, the red oxide alone will probably be enough. An artists paintbrush is quite useful for these very small jobs.

Thank you, much appreciated.

Blob of grease on the bolts also helps, as it sweats protecting the steel.

Bit late, but would Jenolite or a similar rust converter actually be effective on fresh holes in steel, where rust has yet to take effect? Would an epoxy over a zinc spray be better?

Thanks mate. I’ll try that.
