Let's talk about rust!

[69a100]

This isn't a car discussion but it's a subject we're all too familiar with! This is the bottom of my garage/basement overhead door, as you can see there's some issues that I want to address before putting bubble wrap on. The first 3 pics are from the inside bottom, as you can see the center has been eaten through. The rust has crusted the nut/bolts that holds the weatherstrip trim piece so it's lookin like those will have to get ground off, and have to use sheet metal to fab that piece that holds the weather strip as that's pretty trashed.
I have some POR-15 left over from a different project, should I use that or get some SEM rust-mort and go over it with that? Maybe do both? It doesn't have to look good, just better and stronger than this. What do you guys think?

scratch the shale off with a wire brush or wire wheel brush. Get off as much as you can for a more effective result. Then brush the rust mort on. If you have access inside. Use a squirt bottle with rust mort , spray the inside if you can. Leave for a day. Wipe off residue with a damp rag. Let the moisture from the damp rag evaporate . Then apply your por 15 . Both are great products.

Lookin like I'll have to do some fiberglass repair/reinforcement as well! All this is from over 50+ winters of condensate on the inside of the door! The fun of home ownership! Snapped all but 2 bolts, so that was easy!

Replace with new galvanized steel.

To bad you could not find a sheet metal shop to cut and bend a piece for the bottom. And rivit or screw it to the bottom. A new piece would save you alot of work.

That is the bottom of a 7X8 foot door, you tell me how that works???

How much of the bottom is rotted?

Bro you got your hands full on this project!!! I don't envy you at all either but I know you will DIY it as you have done with so many other fixes you have had to Improvise Overcome, and Adapt...to...Bro Rugg

Mostly that middle section, the last 2 pics in post #3. After lookin at and studying the situation, I got a game plan on replacing/reinforcing things, I'm mostly looking at putting the rust in check I'm currently worried about!

Replace with new galvanized steel.

Check your local overhead door company for a new door bottom.

BTW, where's the rubber seal on the bottom to keep the wind and rain out?

I don't want a new door and I see no way they'd repair it, they'd just replace the whole door. Give me the money and I'll go that route! There's nothing close as I've already looked.

Stainless. Might be worth the expense.

If it were mine I'd replace that bottom piece, you'll spend more time repairing it with lesser results but that's just me.

I agree. I think you are just delaying the inevitable...................been there, done that.

PEOPLE PLEASE! The door is a ONE PIECE unit, you tell me how it'd be repaired without total replacement?

Ah, so it’s a unibody. Un repairable.
Seriously though, I googled extruded metal shapes and found some interesting pieces. Seems like the rusted out part on the bottom would take bolts or rivets. Even the rubber piece could conceivably slide into some of the shapes I saw.

How old is that door? They haven't used that seal in 30 years. The modern seal is rounded on the bottom.

Interesting? I'll look into that. I don't have a lot of space to work with at the bottom of the door without it scraping the ground, I'm planning on working it from the inside.

House was built in 75, and the rubber seal shows its age. I'm just really surprised that the removeable trim piece is in such good shape compared to the bottom of the door. Hope these pics help show what I'm up against.
This is the bottom with trim piece removed.

Closer shot! I've already hit it with some POR-15.

This is the top, what the bottom should look like.

Outside bottom with trim removed.

This was pretty cool.
I know you have steel and this is aluminum,but maybe. Then again it may be cheaper for the door, if they still make that door.
