PAINTING PARTS
This procedure reduces the amount of sanding needed to produce a nice, smooth surface on Z Corporation
parts.
1. Depowder and dry the part.
2. Hand sand the part with 230 grit sand paper lightly.
3. Mix BCC Proto-Kast (BC8163 Proto-Kast - White) urethane. Proto-
Kast is a 2-part urethane. Mix with a third of lacquer thinner. This thins
the mixture and retards the hardening
process. For example, if you were to
make 150 grams of the mixture, take
50 grams of part A, 50 grams of part
B, and 50 grams of lacquer thinner.
(BCC products can be found at http://www.bccproducts.com/p3.html).
4. Infiltrate with one coat of BCC Proto-Kast urethane mixture by dipping,
dripping, or brushing.
5. Apply 10 light coats of Sher-wood sanding sealer by spraying.
6. Apply laquer primer by spraying. A hand-held, air sprayer will be necessary for the highest quality surface
finish.
7. Apply colored lacquer gloss paint to achieve the shiny, plastic-like finish.
