Not a reliable masking product [SEP] I’ve not had very good experience using this product.  It brushes on easily and is water based so it is supposed to wipe off easy with water after it has dried.  However, after painting over it trying to remove the paint mask film has been an absolute nightmare.  I’ve literally spent HOURS scrapping away the masks with a toothpick into crevices and even then some spots remained.  I’ve tried masking tape on which does lift some up but you have to be careful not to lift off the paint around it.  If I wanted to be scrapping off paint I’d have just not used this stuff at all and just painted right over clear parts and windows.  Would be easier to scrape off paint than this stuff.  Not recommended.
