Comprised of multiple embossed layers of stainless steel with the outer layers utilizing a Viton rubber coating. Compressed operating thickness is 0.040". With MID Sleeves. Cometic MLS (Multi-Layer Steel) Head Gaskets provide maximum sealing performance for todays high output engines and require no sealants. MLS gaskets are ideal for both aluminum heads to aluminum blocks and aluminum heads to cast iron blocks. They can withstand the shearing force created by the two materials. MLS gaskets have increased strength because they are comprised of multiple layers of stainless steel; which also creates the ability to rebound and resist corrosion. The outer layers are embossed and coated on both sides with Viton (a flour elastomer rubber based material that is heat resistant to 250 C/ 482 F). Viton is designed to meet the demands of a variety of harsh sealing environments, load conditions, and surface finishes. The center or shim layer is uncoated stainless steel, which can be varied to accommodate multiple thickness requirements.This Part Fits:

GREAT - Must buy!
Cannot reccomend these enough. Actually helps turn your burns into tan and reduce redness with the after sun product and the tan enhancer REALLY works. Be careful to let the brown enhancer dry if you're wearing white as it will rub off on your clothes but it did wash out!

Does not absorb all the way BUT STILL THE BEST!
This is THE BEST outdoor/by the pool/by the water tanning lotion ever! I have used it in my tanning bed for years. It gives you a STUNNING rich, brown tan after just a couple of sessions. I will say the browning lotion doesn't absorb all the way so it does and will make a mess! But it does NOT stain ever, it washes right off. Once I am done tanning, I just take a dry towel and remove excess lotion. The after tan lotion is amazing and will turn any little burn into a beautiful tan overnight! My all time fave! It smells like mocha and coffee which makes sense because there's coffee as an ingredient!

Love love love
I have never had a tanning product work so well for me. First off let me start with saying that how quick it works is based off of where you are in the world in my experience. For example, if you are at the beach or an island or somewhere the sun is closer to the equator, it works quicker. If you are somewhere further north, it takes a bit longer, but still not by much. I would say only about a 15-30 minute difference for seeing results varying UV index. This product has definitely made it easier to tan living up north. And the aftercare lotion with this stuff is *chefs kiss*. I would put the aftercare stuff on after laying out on the beach and getting red like Larry the Lobster, then would wake up the next day with a tan and moisturized skin. Plus, with working, it makes it harder to spend my day soaking in the sun(sadly). But I still have a great tan after a week. Also, I am a skincare finatic and this did not make my face breakout or anything. (It does also have a sort of molasses smell but it really isnt horrible). So yes, buy the product. It’s so worth it.

long, tan, & handsome
Love this product. Bronzes even the palest of the Irish type. The after sun lotion is AMAZING. I use it anytime after I spend time in the sun - it really helps lock the color in and keep your skin so smooth and lush.
I ease in, I wear it outside for a bit then put on sunblock until I have a good base tan - everyones different, without sunblock you’ll still burn… (since this isn’t sunblock)
Putting it on is my least fav, hate the feeling of it on my hands, will get on everything in a 20 ft radius of you, but once it soaks in you’re good to go. You will smell like coffee for the next few hours, which is nice if you enjoy the scent.

Great tanning lotion
Wonderful smell but man I burned and I followed the instructions used sunblock .. would recommend small amouts of sun daily to build up a great tan .. the after lotion helps with the burn and smells great too .. learning curve definitely..I will be using this differently going forward.. love this stuff
