LPS 3 Premier Rust Inhibitor, 11 oz Aerosol , hazy brown - L00316

This item is generally only obtainable through Grainger. While not inexpensive, it is a robust treatment for vehicle undercarriage and insides of body panels to prevent rust. It is designed for marine applications however it lasts up to 5 years in Northeast winter environments. Product dries to a waxy finish and is safe on rubber and plastics per the manufacturer. The product does not wash off in car washes once dry like other liquid products.

Been using LPS #3 on my cars for decades. I've used the drain holes in the bottom of doors to liberally spray this inside the door between the two metal panels. My doors don't rust out at the bottom with age like many. Also effective against the brake lines rusting and having to be replaced. Expensive. But little else has contributed to slowing the rust cancer underneath and adding at least a year's life to the car every year I apply to high water / salt + snow areas.

Use this on rusty or stiff hinges, or coat ball hitches that like to corrode in the rain. Recommended.

LPS comes in different grades, which are essentially varied viscosities. Number three leaves a lubricant that has just enough adhesive characteristic that it doesn’t just evaporate or drip off. I used to lubricate the channels and all of the various joints in my garage door to keep it from squeaking. It worked like a charm. In the past, my family used this on boats for variety of purposes, including spraying it on chrome metal to protect it during the winter months from the ravages of saltwater.

as per recommendation of an aerospace engineer and a gun collector I purchased my first bottle (windex type bottle) many years ago to use for a longer term storage on firearms. Well, product does NOT disappoint, as a matter of fact - it preserves my firearms and enhances blue in the metal as well (important, as I do a number of restorations and this is my 'sealer' after applying bluing solution). I found it to be safe on inside/outside/wood/polymer(composite) stocks/inside bores... As a test(my first bottle), I had a take off swede mauser barrel cut in half (not the long way) and left both halves side by side outside in July or August in NE WI. One half was as is, another half was lightly coated inside and out with LPS3 - two weeks later (sun, due, humidity and we had one small rain shower) I went to the back of the garage where these two were... untreated half was rusty inside and out, other half (treated) looked as it was just brought outside. this stuff does NOT cause any long term damage to any parts of the firearm (metal/composites/wood). It will create a fine film (almost wax like), so use your best judgement when applying to firing pin channels, precision triggers and etc - it won't cause harm but it will affect mechanical performance with added friction if you do not clean it and apply heavy (same goes for your first /cold shot in the barrel - I run a patch with a more viscous gun oil). I use both, this spray and a windex type bottle. for cold weather users - it will thicken, so be advised as far as firearms moving parts or if taking your treated with LPS3 item outside in colder temps (made a mistake once hunting rabbits at 0F and bolt stooped cycling in a semi-auto 22 :), so I do wipe off now when going hunting and target shooting in the cold- or at lest, the moving parts )... for long term safe storage, vaults, cabinets, crates - nothing better in my trials.

The rust inhibitor itself is great. The packaging it arrived in not so much. Had a very rough trip. Several dented cans and one had the spray button sheared off. All things I can deal with, but knock it down a star.

While performing annuals, A&P Mechanic used this a lot. Controls junctions and cables within the wings. Anything that needed to resist surface corrosion and light lubricant in areas where dust and dirt didn’t adhere to. I use it today in place of WD40. Stays once dried.

Used this oily ting for many years on spare tires under the back of my pickup or other places I needed a semi-permanent oily rust inhibiting coating. Always worked for me.

大変良い商品と聞き、購入しました。一年～二年間の錆止め効果が有るとの事、結果が楽しみです。

I was told this product is the end of rust in the workshop. I sprayed milling paralells, they rusted where they made contact. Sprayed a milling table, seen some rust afterward... Really not impressed. I feel I could have use butter and have the same result...

This works. Although I have only tried it on products stored indoors. It forms a waxy layer on the product and prevents rust
