For solidified resin, the fastest way to remove it is physical removal, such as grinding and shovel cleaning, etc. As for chemical corrosion, etc., I think it is not suitable for the conventional fiberglass environment.
Once the resin glue has solidified, it may be difficult to remove it. Here are some possible ways to try to remove the solidified resin glue:
Physical peeling: Use a scraper, scraper or similar tool to gently scrape the surface of the resin glue and gradually peel it off. This method may be suitable for thinner layers of resin glue or larger blocks of resin.
Solvent treatment: Some solvents can soften the resin glue and make it scrapable or wipeable. Common solvents include acetone, alcohol, vinegar, lemon juice, etc. First dip a cotton ball or cloth in the solvent, and then gently wipe the surface of the resin glue until it gradually dissolves or becomes removable.
Heat treatment: Heating the resin glue can soften it, making it easier to remove. Use a heat gun, hot water or other heating source to directly irradiate the heat on the resin glue to soften it, and then use a scraper or similar tool to scrape it off.
Please note that the above methods may cause damage or discoloration to the surface, so please test it in an inconspicuous area before application. In addition, appropriate personal protection measures, such as wearing gloves and eye protection, are also necessary.
If none of the above methods are effective in removing the resin glue, or if it causes unacceptable damage to the surface, it is recommended to consult a professional cleaning service or professionals in related fields for more specific advice and assistance.
