I always used Methylene Chloride and 10% Acetic acid by volume. The Acetic Acid slows the reaction and evoporation down.
I spaced the joint with 0.01" Pt wire spacer and used a 20cc syringe with a 24 gauge needle with the point ground off. Squirt the solution in the joint and let the surfaces soak for a minute or two (60- 120 seconds). Then pull the spacers out and clamp it up.
