If you've ever had a sticker on your car or boat that just wouldn't come off no matter how much elbow grease you put into it, then you know how frustrating it can be to remove stickers from fiberglass. But don't worry, there are a few tricks of the trade that can help make this sticky situation a lot less stressful.
One of the best ways to remove stickers from fiberglass is to use WD-40. Just spray some onto the sticker and let it sit for a few minutes. Then, using a putty knife or razor blade, gently scrape away at the sticker until it comes off. If there's any residue left behind, simply wipe it away with a clean cloth soaked in soapy water.
Another method that works well for removing stickers from fiberglass is using heat. Grab a hair dryer and turn it on to its highest setting. Hold it about six inches away from the sticker and direct the hot air onto the sticker for 30 seconds or so. This will cause the adhesive to loosen up and make scraping it off much easier. Just be careful not to hold the hair dryer too close to the surface of the fiberglass, as this could cause damage.
If all else fails, you can always try acetone nail polish remover or rubbing alcohol. Simply soak a cotton ball in either substance and apply it directly to the sticker. Let it sit for several minutes before gently scrubbing at the sticker with a putty knife or razor blade until it comes loose. Again, if there's any residue left behind, simply wipe away with soapy water and buff dry with a clean cloth
