Construction techniques vary according to the material used, but unless noted otherwise, no advanced skills are necessary if you are reasonably good with handicraft skills. Simple fettling tools (modelling knife and a fine file), adhesives (two stage epoxy or cyanoacrylate superglues), car spray paints etc may be used, with tinlets of enamel paint for details. It is important to de-grease resin and white metal kit components thoroughly before painting. Clear window mouldings are usually vacform plastic, and are best fixed in place using a blob of white pva glue (as used for woodworking), under the roof of the car, because this adhesive goes clear when it has dried. Most decals, where supplied, are of the waterslide type. If a kit is very complex, or if in our opinion it demands more advanced skills, we note that in the description.
