I read a guide online once that Atsushi Hara made about the HB Cclone TC car.
He used to get some CA activator, spray a load onto a paper towel, wipe all the chassis edges wih it then dribble a bead of CA straight from the tip of the bottle down the chassis and let it flow around the chassis edges.
You can do it without the need for the activator too..just dribble a small amount starting from the top and work the chassis around as the CA flows around.
Tis easy if you have patience
