I just upgraded my sonar/GPS from a 5" Lowrance to a 9" Garmin on my Lund Fury 1400. Part of the project is to add a poly transducer plate using epoxy (or similar) so that I'm not drilling more holes into the aluminum. (I'll need to fill the existing holes from the Lowrance.) I've purchased some 3/4" poly material to use for the plate.
I've watched a few vids on YouTube and have seen different approaches to this. I think I'm going with 3M 4200 unless someone can steer me clear of this. Also, after scoring the aluminum on the transom, is it required to use a 'self-etch' primer to condition the metal before applying the adhesive? Or is it sufficient to just score the aluminum (wire brush?) as well as the poly?
