How to Remove Gel Stains on Fiberglass Doors

Gel stain is a thicker stain that is commonly used to stain vertical surfaces such as doors and walls. This is because the stain will not drip and run like liquid stains. When staining fiberglass with gel stain, the stain will not soak into the fiberglass like stain does with wood. Because of this, it is simpler to remove stain from fiberglass doors. Always use gloves and goggles when using chemical strippers to protect your skin and eyes.
