In which hardware stores can I find silicone rubber?

“NextClear” is a professional, two-component high-solids top coat. The product is a durable and glossy high-solids top coat with a high gloss. It is the best way to touch up your table using spray cans: it is highly resistant due to its high solids content, and the high gloss gives maximum shine – two basic characteristics of resins and wood. A two-component top coat that works perfectly wherever a polished surface is needed. The glossy “NextClear” is resistant to UV radiation, ageing, yellowing and chemicals. Recommended for resins without phosphorescent pigments, wood and various types of surfaces. Its unique properties meet the requirements for protection, sanding and polishing of resins without phosphorescent pigments, wood and various types of surfaces. Properties: Scratch-resistant protective finish; Prevents resin from yellowing; Resistant to UV rays; Easy to apply; Usable within 24 hours of activation (duration may be even longer depending on storage location); Dries completely in 48 hours The contents of the can can cover approximately 1 square metre. Note: Initially, it has a strong odor that disappears after drying. Use in a ventilated place. Directions for use: "NextClear" should only be activated at the time of use. The topcoat and hardener are already contained in the container as separate components; to start the catalysis procedure, remove the red button from the container cap, turn it upside down and firmly insert it into the pin at the bottom. Shake the container well for a few minutes so that the hardener is well dissolved. Apply to a lightly sanded surface to allow attachment. Apply 2 coats. The high-gloss top coat dries completely after 24 hours. Use the contents of the container within 24 hours of activation (duration may be longer depending on storage location). NextClear topcoats are marked with the QUALITY EXTRA symbol, which is used to mark all products manufactured and tested directly by ResinPro to always ensure maximum performance. REMOVE WITH ACETONE AND/OR NITRO THINNER (before the product dries completely).
