Most paints need thinning for proper flow - sometimes up to 50/50 paint/thinner. Test on scrap first.

After assembly, hold pen upright and depress tip fully to release trapped air. Prevents paint globs on first stroke.

Always shake the pen thoroughly before each use to ensure proper paint consistency and flow.

Hold pen vertically against scrap paper, push down for a minute to prime. Only needed for first use or after long storage.
