1st thing I was ever taught "reverse the damage" .....Just kept tryin through the years to use the least amount of filler "if you can't get it in one fill the metal work ain't done" and after awhile I didn't need any
my first sheet wrote the dodge for a new box side

but customer cringed at the cost

so thought i'd give it a try.
was alittle extreme but , shows what can be done with some time and patience
similar to PDR but really it's what I call "MIN FILL" (patient pending

)
metal has a memory and using "metal whispering" (patient pending

) you can coax it back to where it wants to be
I'm sure everyone here is referred to as annal

.... and there's a reason forit
Oh I still enjoy diggin in the mud pail on occasion , but , it's just takin the art to another level ...........sky's the limit
