Will this help ?** A: MY SUGGESTION IS GET YOUR WIFE A BB GUN **Q: does this contain zink ?** A: Yes **Q: Is this suitable for assembling a non-synchronized dog-engagement manual transmission?** A: Yes, I'd say that this stuff would work great for any metal to metal assembly. You must be working on an antique tractor transmission? Ben is right though, gear oil is what I'd use for gears that will be in an oil bath anyways. **Q: Does this lubricant work on shotguns in winter outdoor temperatures? I'll be appling it to metal/metal sliding surfaces.** A: Do a lot of shotgunning for ducks in Michigan's Upper Peninsula in sub-zero temps...we use CLP on EVERYTHING that can rust or needs lubing...we just make sure tool wipe off ALL of the access oil. Even though it looks/feels like there is no lube, it IS still there doing its job. This has worked for many different types of semi-auto shotguns in our group for many years now. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by H***Y on February 5, 2026* 今まで指やハケで塗る他メーカー製を使っていましたが、そのまま滴らせるこれが欲しく購入。粘度が高くクリアランスの狭い所には向かなくかなり回転が渋くなります。使う場所によって使い分けしたいと思います ### ⭐⭐⭐⭐⭐ Review *by 安***き on January 25, 2026* 粘度が高くその場に留まりやすいです ハチミツと同じくらい ### ⭐⭐⭐⭐⭐ Review *by マ***ン on May 24, 2025* かなりまとわりつくので、ピンポイントでオイルを塗布したい場合に流れません逆さにしてもしばらく垂れて来ませんので、作業性良し。 塗布後も長期間保持していますので、エンジンOHに使いやすいです。 パーツクリーナーをサッと噴いても少し残りますが、エンジンオイルにはすぐに馴染むので、グリースとオイルの中間といった感じ。 ## Frequently Bought Together - Permatex 81950 Ultra Slick Engine Assembly Lube, 4 oz. , Red - Moker Piston Ring Compressor Tool,Car Engine Piston Ring Installer Removal Kit，Adjustable Sizes From 2-1/8 Inches To 7 Inches (53mm - 175mm) with Piston Installer Plier - Permatex 80037 Valve Grinding Compound, 3 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.us/products/748598562-permatex-81950-ultra-slick-engine-assembly-lubricant-4oz-81950-4oz](https://www.desertcart.us/products/748598562-permatex-81950-ultra-slick-engine-assembly-lubricant-4oz-81950-4oz) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-04-26*
