1⁄35The Future Is Klear
This method is very easy to do but like all techniques I would suggest a trial run first. I have tried airbrushing Klear but much prefer hand brushing. I was always worried that my airbrush wasn't free of Klear and it sprays like water so it is very easy to get pooling, which is difficult to remove.
A word of caution, as previously mentioned Isopropyl alcohol will strip Klear. It will also strip paint, so if you mess up the Klear on the painted model don't try and strip it off with Isopropyl alcohol. I have never needed to remove it.
So, The Future Is Klear
To recap: Use a soft flat 1/2" paint brush. Dip the bristles into the Klear about half way. Remove the excess by scraping the bristles over the edge of a container, not the container with the Klear in. Paint on the Klear carefully, don't rush. If you cause bubbles to develop remove at once, by going over the area, carefully (if the Klear has started to dry, dip the brush again), don't let the bubbles dry. Apply 2 coats before decals and 2 coats after decals.
CAUTION: Always read the label before using any substance.
