Guys, the air ducts connecting to left and right air vents are ripped on couple of places. They are cloth kind of material and a bit dusty and tape doesnt stick. Want to keep the original ones as I put the dash back in.

Any tips what to use to seal or repair these rips?

This older but might be helpful.

Found the right solution…aluminum tape. Here is the original in dash hose. Planning to wrap all of them.

Then spray them black!!

Foil tape doesn't hold paint well. It might if it doesn't move much

My bad I thought he was using more of a robust material.

I guess you really don't see these with the dash in. I'd worry if I were doing a period correct restore but if I was making the car "my car", who cares!

The tape sticks very strong. In fact as you can see u can also press it to go in between hose spaces. Pretty happy with it. The original hoses were ripping at few places, now they gonna last another 50 years. I had noticed the original hoses on the inside has foam, this makes the flow of air more smooth. Plus they go on the inside so probably not worried about the silver appearance.

I like foil tape. I use it a lot at work. It sticks really well and is nice and malleable

Everything look nice and tight. Appreciate everyone’s input guys. Waiting for the clock to arrive so that dash can go in.

You can also look at some of the great duct products for marine. Here's a link to something I've used in my boat. It's much stronger and won't rip like other thin products. Doesn't look like you need much but at least it's an option. https://www.fisheriessupply.com/trident-marine-trident-polyduct-hvac-duct/481-3000
