Structural Adhesive is bloody expensive !! I looked at getting some for the new slam pillars on my 90 and ended up doing for a poor cheaper option. I should have used Tiger Seal I think as that stuffs brilliant.Something I have been doing at work recently on truck floor paneis, 2mm steel plate, structural adhesive and 1/4 inch mono bolts.
Not sure if it is mot spec, but it is bloody strong.
