Ray W (Yar),
If you have owned a Chevy pickup anywhere after the mid 90's you have experience with panel bond. The door hinges are bonded to the body---no weld no bolts. Haven't noticed a lot of Chevy pickup doors that have fallen off and are laying on the roadway which is pretty good for Bondo. Might be best to watch for parts falling off an F22 or F35 JSF fighter since they are "Bondo'd" together. I will go back to rivets and weld right after I move from my house back into a cave.
