CA glue for parts that are not chrome or painted gloss. (fogging issues) Strong bond but inflexible.
Testors red for most everything once paint has been scraped from contact points. Minor flexibilty but is best left to cure 24hrs.
Testors window maker for clear parts and for bumpers because it wicks into gaps and dries clear. Note: gravity helps with wicking.
Future/Pledge for painted, detailed foiled, decaled bodies to seal everything down. Boo boos can be redone after cleaning off with ammonia base cleaner. Can be brushed on suprisingly heavy. Any bubbles will disappear on their own. NEVER reacts with paints or decals like some clear coat aerosols.
I have Plastruct Bondene but I have never been impressed with the adhesion unless used on a large surface area.
