To remove dried epoxy from surfaces, start with the least invasive method. Apply heat using a heat gun or hair dryer to soften the epoxy, being careful not to damage the surface. Once softened, use a plastic scraper or putty knife to gently peel away the epoxy. For stubborn residues, apply acetone or isopropyl alcohol with a cloth. Dab gently, allow it to sit for a few minutes, then scrub away the softened epoxy. Always wear gloves and work in a well-ventilated area. For delicate surfaces, test a small, inconspicuous area first to ensure the remover doesn't cause damage.

It seems there might be a typo in your question, but if you are asking about the reliability of resin products (possibly "reliable resin" was meant), the answer is that it largely depends on the specific product and its manufacturer. Resin, as a material, is widely used in various industries for its durability and versatility, particularly in crafting and manufacturing. When sourced from a reputable supplier, resin can be highly dependable for a range of applications, from jewelry making to tabletop gaming miniatures and even in construction. However, the market also has its share of lower-quality resin products, which may not meet expectations in terms of durability, clarity, or curing properties. It's crucial to research brands, read reviews, and perhaps test products on a small scale before committing to large projects or high-volume purchases. Ensure that the resin you choose is suitable for your specific application to maximize its reliability.
