JB putty

I'm installing my floor pieces, [toe kick, and fillers on the sides of the set back firewall on my 30 Ford coupe. I welded the fillers in but have some small gaps that I thought I could use some liquid steel in a tube, then I found this J B putty over at the zone. Has anybody used this product? It covered the holes really well but I was wondering if it might have a tendency to rust. I was thinking of using it where I have some gaps under my visor at the windshield in the upper corners. I would have a hard time welding thoes holes shut but I might be able to get a small piece tacked in and then use the JB to seal it? Bill

JB weld is really not what you should use in this situation. I would go with a reinforced fiberglass resin with a hardener. You can sand it and cover with a thin coat of putty to smooth.
The JB weld will not sand smooth enough to put paint on.

JB Weld is some fantastic stuff when used for what it was designed for. It is not best suited for what you used it on. No it will not rust as it is not metal.

I used some on an old bicycle that I restored 8-10 years ago. It had a couple of fairly deep dents in the top tube of the frame,I had to use a file to get it smoothed down, but once I got it finished it was invisible.

For a small repair and if the 'right' material wasn't available, I could see using it. But it's an expensive thing to use in any real quantity.

If the welds are structurally adequate and all you're trying to do is seal pinholes, why not use factory-style seam sealer?

JB Weld isn't a putty. Its a very strong and dense epoxy filler. It's hard to sand but that's because its so strong. It's very good for fillets and securing things in place where a smooth finish isn't necessary.

Ok Guy's thanks for the help. I did use it on the toe board pockets and it looks pretty good but I will go with the seam sealer for the rest. I will try the glass and hardner on the visor side holes cuz there out there where everyone can see. Thanks again, Bill
