Red Line Synthetic ShockProof™ Gear Oil provides unequalled protection for high performance differentials and transmissions which are heavily loaded or which see shock loading. This revolutionary lubricant is completely different from conventional lubricant technology in several ways. The viscosity characteristics are significantly improved. Gear teeth need high viscosity at high temperatures to prevent metal to metal contact and a low viscosity when cold to reduce fluid friction. The ShockProof™ chemistry significantly reduces the thinning effect of high temperatures. The Heavy can be rated as a 75W250 Gear Oil, but has the lower internal fluid friction of an SAE 75W90. The Lightweight can be rated as a 75W140 Gear Oil, but has the lower internal fluid friction of an SAE 30 motor oil. The SuperLight can be rated as a 70W90 Gear Oil, but has the lower internal fluid friction of an Automatic Transmission Fluid. These ShockProof™ lubricants provide much greater viscosity in the thin layers between the gear teeth, but have very low internal fluid friction, which means very little power loss for the protection achieved. ShockProof™ Gear Oil has a 40 Percent lower coefficient of friction and 250 Percent the load carrying capacity compared to conventional gear oils, which means that metal to metal friction is greatly reduced. Temperature reductions between 25 to 75 Degree Fahrenheit are common in circle track, road racing, and off-road racing. Improved durability in high performance use is the primary benefit of the Heavy ShockProof™ and along with the improved durability is an improvement in efficiency, but if further improvements in efficiency are desired, and durability is not a major concern, Lightweight and SuperLight ShockProof™ can be used. Red Line ShockProof™ can be used in conventional, limited slip, or locker differentials. Red Line ShockProof™ is designed for use in competition differentials and transmissions.

Works well to prevent sunburn and stays on while working.
Size: 6 Ounce (Pack of 1), Style: Spray
This sunscreen is great! I've worked outside in New Mexico sun for the past few years and this is a life saver. Goes on evenly and doesn't come off while I'm working in the heat.

Fabulous, especially for sensitive skin and those with aversion to textures.
Size: 6 Ounce (Pack of 1), Style: Spray
Keeps my skin from turning UGLIER.
THIS actually WORKS. I do not wish to be any tanner than I come naturally, and this is the BEST sunscreen I've ever used. I do use a wipe to remove the overspray from my eye area.
It does not irritate my incredibly sensitive skin, and sprays on easily..like a dream. No more sandy spf moments!..I can't stand that creamy+oily stuff all over my hands then throw in a little sand - now we have a sensory concern..NOT WITH THIS STUFF!! Highly recommend.
Easy to use. KeyWest rays had nothing on this..we came back slightly tan, not burnt, and not a looking like a different ethicity. Reapply as recommend.

Best Sunscreen Ever

BEST. SUNSCREEN. EVER.
Seriously. My skin is paper-white and I'm highly tattooed, so sun safety is very important to me. 100 SPF for total protection is unbeatable and I have yet to burn even a little. I'm also very texture-sensitive so I can't stand thick, gloopy, sticky lotions. This one actually sprays on clear, soaks in right away, is light, and even a little bit refreshing. The spray mechanism also makes it easier to get my back without help. There's no off-putting smell, no mess, no problems. I do reapply if I'm out for a while so I'll need to reorder soon, but I'm not mad about it at all. It's very affordable compared to the alternatives and entirely worth it.

Still fried.
Size: 6 Ounce (Pack of 1), Style: Spray
Smells good and you don’t feel it after applying it. My son and I still got sun burnt which is normal for our fair skin. I’ve never blistered before and using this I did even reapplying half way through my time of being on the beach for an hour and most of that time under an umbrella.
