Hot Rods best practices for bondo application?

My late cuz told me about a guy that stuffed a loaf of bread into a big dent on a quarter panel and then bondoed over it. Maybe the same guy?

 

This is too thick. HRP

 

I've found filler like that that still stunk of chemicals and still soft, even though it was years old.
Rule of thumb: thin as possible and sand most of it back off.

 

Anyone still use lead?

 

Pay someone else to do it….

 

Yup , no shmundo
