Welding Question.

[sponsoredbydad]

I'm about to do the final welding/sealing up of my 69 windshield frame and some floor patches and I'm wondering if their is something I can put on the inside to keep it from re-rusting. I've already used rust converter and sprayed it with cold galvanizing paint stuff but when it gets welded that stuff will burn right? And the rusting /corrosion will start again everywhere is gets welded. Is there anything special pro's use before welding or do you just grin and bear it ?

i'm very interested in this as well. I am going to be doing my winshield frame in the near future as well.

Try this stuff. It works great. I used it when I replaced my inner rocker panels. It is not intended to be painted over but used in the interior space between panels.

Sorry I guess that I cannot post URL's yet so try a search for this...

Eastwood Company

Cold Galvanizing Compound Aerosol 14 oz

It's $16.95 a can but goes on very well.

Thanks, that's the stuff I used already well not eastwoods but same stuff. But after you weld and you can not get in behind to spray more on the burned stuff from the welding is what I'm wondering about.

According to Eastwood it resists burning off the weld area and what is burned is supposed to still guard against rust. It beats nothing I guess but I also sealed all my seams with seam sealer and said a little prayer that it will hold up.

Hea Thanks
I guess I'm just gona go for it. Thought about it last night and if it lasted 30 years coming from GM without anything then well I'll be around 80 and It will be my kids problem then HA HA HA

That's exactly how I'm looking at it! I figure hell I drove this thing around with the rust holes in it before, if it doesn't last I guess I can enjoy it in the meantime and then drive it around with rust holes in it again. Good luck.

plus if you can get away with any hidden holes, i would suggest spraying oil in there, probably after it's painted, but that will keep everything from rusting, too... remember Zeebart...?

From what I have heard not sure if its true or not. But the reason you shake it really well it to make sure that its evenly sprays out. that way way when you do weld the "vehicle or liquid" does burn off and the "pigments/ shinny metal crap" stays protecting the surface after being welded.

Work from the inside-out. Meaning seal and protect from the farthest places you can reach as you go. The final seal can be as simple as drilling a hole just above your final weld and spraying it with the medicine of your choice. Then either tack weld the hole shut, or do like Zie-Bart did, and rubber plug it. BTW, they didn't spray oil... And IIRC they reached the further areas with rubber hose type attachments.
