Bond a fiberglass scoop to a steel hood
This is a fiberglass scoop on a steel hood.
It has 6 mounting studs.
I drilled the hood for the studs and set it on, the used a magic marker and outlined the scoop.
Then I took it off and while staying inside the marker line, removed the paint 1 inch inside the line and sanded it hard with 60 grit, and the same with the scoop where it contacted the hood.
I drilled 1/8 holes every inch or so where the two would mate up.
Where that contact area was going to be I buttered the scoop and the hood before placing the scoop on and tightening up the the 6 nuts. (Before the Bondo short strand set up)
Once it was on and tightened down I started working on the contouring from the scoop to the hood.
It’s been 6-7 years now with no cracks or delaminating.
