Kits that we have rated as skill level 4 require all the same modeling techniques and tools as skill level 3. However, these kits tend to include more and smaller parts, the use of multiple materials (resin, white metal, photo-etched, etc.) to complete the kit, and the need to perform some modifications to the parts before they can be used, such as changing their size, opening holes, etc.
To properly complete a level 4 kit, you will want to have all of the skill level 3 tools. In addition, a pin-vise (hand-powered drill) and plastic saw will assist in modification of parts when necessary.
Kits in this class are not suitable for small children at all. Children under 14, even if experienced, are likely to have difficulty with a kit like this if they attempt it alone. Adults who have never before completed a plastic model kit are advised to avoid kits of skill level 4 or 5 until they have gained modeling experience working with something less challenging.
Examples of kits in skill level 4 would be injection-plastic kits of cars or aircraft that include resin or white metal modification parts, or kits that call for you to cut or otherwise modify existing parts in some way. Many resin figure kits with many parts would also fall into this class.
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.
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.
