I've been on the measure once drill twice plan once or twice before myself.

Looks good and even better once some rust proofing goes on. Sooo much easier to get it all covered when you can stand up rather than laying on your back with stuff dripping in your hair and safety squints.

I got the bottom all coated in zero rust

Then I wire wheeled the inside bed floor in prep for either a rust paint or bedliner, I can't decide yet. Anyway a few rust holes appeared, at least only in one spot. One more thing to do before this goes on the truck...

How did you like the Zero Rust? We use it a lot at work and I've sprayed it on a couple of my own projects.

Never fun when you find some rust holes, but at least it's not too bad. Making good progress!

Obviously only time will tell, but so far I really liked it. Thinned it about 15% with acetone and sprayed with HVLP. It was super easy to work with and it feels like it has good texture and sturdiness. I will use again for sure.

I managed to quickly fill the holes with weld rather than making a patch. It kinda wanted to blow away since it is all thinned out, but I managed. Not the best way, but good enough for now, and it's getting covered in bedliner anyway.

It was a productive day. After fixing the rust holes I got the bedliner on.

All prepped

And bedliner on

Finally the bed should be ready to put on the frame.

Looks good! Pinholes are always a pain. I think I'd almost rather just fit a rotted section - almost :shock:

What bedliner did you go with?

It's called EZ Liner from Dominion Sure Seal. Fairly inexpensive but has very good reviews at Canadian Tire. Went on fine, I will know more about quality when it is good and dried.

Finally got the box mounted and this how-to is a wrap. Luckily all my measurements worked out and it sat right and holes lined up fine.

Here is the underside showing some of the standoffs and extra brace.

I used regular 1/2" carrriage bolts, not anything vehicle specific. They look great and you'd never know they were moved.

And here is the truck.

Turned out nice, fits like factory! Some trim and a little paint work and no one would every know that's not the one it was shipped with.
