Hi Reilly
When I originally posted I anticipated bonding to bare metal. There had been some discussion on the board about older generations of powdercoat delaminating. In my case the powdercoat was done very well. Maybe they improved in later years. I ended up scuffing, using aktivator and 209N with very good results.
I also tested this with acrylic coupons against bare steel and aluminum using a 1/2" square attach point and tested that to 50 pound pull at varying thicknesses from 1/16", 1/8" and 3/16" sikaflex and never failed. Also tested in 30 degree C differential with same results. So, powdercoated, bare aluminum or steel I'm pretty happy about the results. Not flying yet with it but much prefer this over hundreds of tiny stress points.
Hope that helps.
