Aluminum Bases are available in three grades: Fine, Medium and Coarse. They are highly reflective and intended for use as an undercoat for the 4600 Series Candy Colors. Aluminum Bases may also be used alone for an aluminum-like, reflective finish or as an undercoat for Series 4200 Transparent Colors for reflective, custom effects. Use of the different grades against one another with a Candy Color top application create fantastic effects.
Highly reflective – more so than 4300 Series silvers.
Best applied over 4002 Sealer Dark or an underlying coat of Auto Air, not direct to the substrate.
Aluminum Bases are may require a longer period to cure than what is required for most other Auto Air Colors due to coating used to prevent aluminum from gassing.
Use of mid-coat prior to aggressive masking for graphics may prevent peeling.
Mid-coat may be of a urethane inter-coat clear or Auto Air 4004 Transparent Base.
Use of mid-coat may not be necessary, especially if Aluminum Base Colors are thoroughly cured.
Intended for application with a spray gun or large tip-sized airbrush.
