Hi guys. Got a bunch of holes to fill on my 2007 Grand Caravan. My local metal guy has 4'x8' for about $70.(no I don't need that much).

Now, I've heard that 18g cold rolled is the go to sheet for this kinda job, but the metal guy says this is good. Note I am buying a few more years, not entering the beast in a car show. But I've not done much in the way of body work...

Thoughts..??

Thanks

All my repairs have been 18g. Geez I paid $70 for 4x2 piece. Got about half of it left.

In most modern cars the sheet metal is 0.8mm which is 21 gauge. 22 gauge is 0.7mm which is going to be difficult to weld without blowing holes everywhere.

Going a little thicker (0.9mm) would be a better choice but 1.2mm (18 gauge) is a bit too heavy and will transfer the problem to the old metal, apart from being more difficult to shape.

Dang, that's what I was afraid of. Thanks.

I did end up going with a sheet of 20ga cold rolled.
