What am I missing... Both Sika's website, and Jamestown Distributor's website, which sells the Sika line, require the use of a primer on aluminum & steel that, as far as I can tell, nobody uses. I don't know about you, but I would think that following the manufacturer's instructions TO THE LETTER would be highly advisable on your canopy where you really only get one shot to get it right.
The way I am reading this, Sika 209N primer is required on the plexi side, and Sika Activator and Sika 206 G&P are required on the aluminum or steel side of the bond.
Yet Mickey Coggins' site and the Matronics site regarding canopy bonding- widely considered the authority and central knowledge base for Sika canopy bonding, does not mention Sika 206 G&P, unless I missed it somehow.

Additionally, a search of Sika 206 G&P doesn't turn anything up on VAF either.
Check my math. According to:
http://www.sikaindustry.com/primer_chart_4-21-06.pdf
our application is an "application involving large components where there is joint movement. examples: "...WINDSHIELDS, side windows". The joint movement arises from the difference in thermal expansion with temperature between the aluminum and the plexi. Thus our application is a LEVEL II sealing / bonding application, and requries scothhbrite, followed by SIKA ACTIVATOR, followed by SIKA 206 G&P on untreated aluminum and steel.
Similarly, videos on Jamestown Distributors website call for the 206 G&P:

Yes, this will add to the cost of a Sika installation because these primers and cleaners aren't cheap. However, this is no place to cut corners. Why then, does it seem that nobody has used the Activator and 206 G&P primer on aluminum & steel as required by the manufacturer for our application?
