Technical Using different gauge sheet for patch panels???

Excuse my lack of knowledge...

Say a body panel is 18 gauge, can you use 16 gauge to patch it or is that asking for trouble?

 

I find most vintage cars to be around 19 gauge, I use 18 for patches on them. 16 is pretty heavy for body repairs unless for structural.

 

Use 18 gauge !!! You will be much happier with your welds. Mis-matched gauge will result in uneven heating of your metal and can produce some "Funky Welds". When you metal finish your welds, you will find that mis-matched gauge will be a "PITA" to hammer and dolly............. Jeff

 

It can be done but metal is sold by the pound. 16 gauge weighs more then 18 gauge.

 

16 gauge is harder to work with. HRP

 

stick with 18 gauge , it's closest to most cars original thickness and is easier to tweak
