Assembly Guide
Skill Level 1:
Very Easy to Complete
Skill Level 1 kits require some minor assembly, but are so simple anyone can do it. Such kits seldom require cement or paint, but read any additional explanation provided to be sure. With the possible exception of a pair of plastic nippers, no special tools or supplies are needed to complete a kit like this.
Cement Required
This item requries the use of cement (glue) to complete. For injection-plastic kits, use the weld-type clear cement specifically designed for use on styrene plastic. For some smaller parts, you may wish to use instant type (cyanoacrylate) glue. For resin, white metal, soft vinyl and photo-etched materials, the use of instant type cement is strongly recommended.
A SAFETY NOTE ABOUT INSTANT CEMENT
Parents and all modelers should note that instant cement (cyanoacrylate) bonds skin instantly. While this in itself is not harmful, forcibly attempting to pull the skin apart can tear the skin and cause injury. If you or your child happens to inadvertenly glue themselves with instant cement, don't pull, but use remover for instant cement, or nail polish remover to dissolve the bond instead.
Painting Required
This model kit or accessory must be painted in order to achieve a realistic appearance.
While there are slight differences depending on the country you live in, there are generally three types of paint available for modeling: Acrylic, Enamel and Lacquer. Their characteristics are described below.
