The aluminum base colors are made with highly reflective aluminum flakes and are ideal as a standalone silver finish, or more commonly used as a base for candy colors. Although the aluminum bases are incredibly flashy their special properties do require a certain amount of pampering during the curing process and the layering of coats.
Start with 6013 AutoBorne Silver Sealer. When painting large panels, bike tanks & fenders, complete vehicles, apply 4100 Series Aluminum Bases as a mid-coat over AutoBorne Silver Sealer to achieve an even metallic orientation. When applied over a black or non-metallic base as a base color. Aluminum Base can appear splotchy on side-cast views despite an even application that looks well orientated on direct views; this is a unique characteristic of the aluminum flake.
Aluminum Bases are sensitive to touch. Do not wipe clean or scuff after painting as any direct contact will create visible streak marks in the final finish due to the aluminum flakes being bent & crushed when wiped. A clear top-coat or candy mid-coat is recommended soon after Aluminum Bases have cured. Apply 4004 Transparent Base or 4030 Auto Air Inter-Coat if extended time is planned before top-coating as inter-coat will protect from direct contact when cleaning prior to clear.
Coverage: Aluminum Bases cover well as they’re applied as a mid-coat 100% coverage is not intended as dimension is created by allowing some of the base to be visible in the final finish. Avoid excessive material build-up as this creates mottling and a splotchy finish.
Aluminum Bases are best applied with a spray-gun or large tip-sized airbrush. Refer to Hard Surface Application Guide for further application information.
