I couldn’t get more Dicor in time so I ordered this product. Using them back to back, its very similar to dicor. This product maybe 10% runnier, thats all I noticed. Runny is fine in my opinion as you want it to flow out. overall, good product So far, time will tell. See photos, the antenna is sealed the Dicor and the 2 vents are sealed with this product. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/260247588-ziollo-rv-flex-repair-caulking-lap-sealant-4-10-oz](https://www.desertcart.vu/products/260247588-ziollo-rv-flex-repair-caulking-lap-sealant-4-10-oz) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-05*
