This video shows Gunmetal grey as a base coat and plastidip pearlizer on top.
This gives the finished project an alloy / silver look.
The next part of the video shows Gunmetal grey as a base coat and plastidip Smoke as top coat.
This darkens gunmetal grey to a nice finish.
When applying plastidip gunmetal grey as base coat, get good even coverage on your surface.
approximately 3 to 4 coats until the colour is uniform with no shade difference.
Then add pearlizer until you get that silver look, two or three coats.
Using the plastidip Smoke, do not add to much or it will go black.
