Hi All,
So, I have a shipment of Proseal somewhere between the US and Tasmania, but I am at the stage I need to close out my elevator. As a substitute for using the Proseal for joining the elevator stringers at the trailing edge, I purchased locally some Sikaflex 252, which according to the product sheet is suitable for such an application. I am applying it to stringers I have primed with zinc phosphate etch primer and discovered in the Sika pre-treatment chart that although 252 can be applied to primed aluminum surfaces, the surfaces should be pre-treated with Sika Activator. Of course, no one stocks Sika Activator here, so I am wondering if I can just prep the surface with isopropyl alcohol or similar, or do I even need to worry am I being overly paranoid? Above all of this, should I even use Sikaflex 252 for this application, or should I just put the brakes on things and wait for the Proseal to arrive?
