Good stuff Wayne.
Mike, Andy has described the process, and it really is simple to do. Although Kirby uses liquid cement to attach the clear sprue, most use CA, as the bond needs to be strong for the filing and sanding.
The CA does not affect the clear sprue, as it is a solid 'lump', and the filing and sanding is not hard to do, as clear sprue sands and polishes much easier than 'solid' plastic. I normally do the final polishing with 'T-Cut', a car body colour restorer, but metal polish, or even toothpaste, works just as well.
The entire process, to make two wing-tip lights, fitted, and finished, takes around 90 minutes - and that's with my knackered hands.
