The low setting still puts out a little more than I need, but easy to work around. I just use a small plastic cup to put the grease in, and use an applicator and/or my fingertip (wearing Nitrile gloves) to apply the grease. It's easy to clean up, I just use 409 and a paper towel, and it cleans any mess right up. I've been using CRC products for a long time and never been disappointed with the quality of their products I use. ## Frequently Bought Together - CRC Marine Premium Dielectric Grease, 3.3 Wt Oz, Non-Curing Compound for Sealing, Protecting, and Electrical Insulating, Pressurized Can with the Select-A-BEAD Nozzle - CRC Marine QD Electronic Cleaner - CRC 05103 QD Electronic Cleaner -11 Wt Oz --- ## 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.jp/products/104346119-crc-marine-premium-dielectric-grease-3-3-wt-oz-non](https://www.desertcart.jp/products/104346119-crc-marine-premium-dielectric-grease-3-3-wt-oz-non) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-06-21*
