"Each SEALITPEN is filled with ONE SHOT brand 4005 UV blocker acrylic clear, for a fast drying (15 minutes), long lasting edge seal. "
Seal It Pens are ideal to seal the edge of lettering, specifically sharp corners that are more prone to lifting. For boats any standard lettering such are registration numbers which might be subject to frequent horizontal water contact can benefit from the Seal It Pen.
When the time comes to remove the graphics, simply clean the surface with mineral spirits to remove any remaining sealer.
***Note: Seal It Pen is not required for domed lettering. Domed lettering will arrive with rounded corners and already be sealed by the epoxy.
