Iwant to fill the drip rails on my 56 F100 & radius them into the roof area.
What is the best method for doing this that will not result in hair line cracks at either the drip rail or the roof.
As tests I have tried bondo & fiberglass but the both have seperation problems. I assume this is due to the thickness of the fill.
Would the old standby of body lead work best?
I could make a 16ga. strip & weld the entire thing in but would prefer not to do that much welding due to warping problems.
