The paint from your Posca pen may be sealed onto a plastic surface by following the instructions given earlier in the article to apply the paint with the pens, and then allowing it to dry on the plastic surface where it was applied. After the paint has had enough time to completely dry, you may proceed to seal the plastic by spraying a sealing agent over it and allowing it to dry.
Apply some rubbing alcohol to a cotton ball and then thoroughly clean the area once again.
