T-88 is a non-brittle structural adhesive which gives superior finished results even when used under adverse working conditions. T-88 will cure in temperatures as low as 35°F which makes it an excellent choice for homebuilders living in colder climates. It is recommended by the builders of many types of homebuilt aircraft and is excellent for bonding aluminum, steel or wood. When fully cured, it is not affected by water, oil, gasoline and most other chemicals.
This epoxy is very versatile for building wood aircraft. It has a wide temperature range for curing and the manufacturer claims the joint strength is not affected by clamping pressure or lack of. Does not smell when mixed and msds sheet lists no known carcinogens or harmful effects to skin or lungs. Latex gloves are strongly recommended due to allergic reaction with skin over time. Use with System Three Clear Coat to seal soft woods prior to gluing. Full joint strength is still maintained according to manufacturer. They sent me an email to confirm this. Their tech support is very helpful. Viscosity of T-88 changes quite a bit from changes in ambient temperature. Dries slow (overnight cure) so it might prevent you from doing as much as you planned each day. Perfect if you only have time to build one rib a day!

What is the recommended surface preparation for an existing self-etched primed aluminum surface when using the T-88 Structural Adhesive?
You just need to make sure the surface is clean and smooth. Our guess is you are using a self-etching primer, like zinc-chromate, or zinc-oxide. T-88 should work fine over that as long as the prep is done properly for those primers was done correctly.
