Pro-Tip: When tackling a heavily seized fan clutch, leave the serpentine belt installed on the pulley initially to provide extra tension and resistance against slipping. Position the pins of your GEARWRENCH Pulley Holder firmly into the pulley mounting bolts, holding it steady with one hand while applying targeted torque to your fan clutch wrench with the other to cleanly break the nut free.

Saved My Skin and Left Me With a Tan (and I'm a Redhead!)
Disclosure: For the first week I did layer the Burn to Brown with Solar Recover Save Your Skin Spray As a redhead who accidentally used 30 spf for a long weekend on the beach - this stuff 100% works!!! 3 months later and I still have a tan!!! Not only did it turn the burn to tan, it also cooled down my skin so I could sleep a little more comfortably! For the first week I used both the Burn to Brown lotion (which I prefer for it's cooling effect) and Solar Recovery spray (which I believe helped more with peeling). Would 100% buy both again, especially if you're like me and spend every free moment at the beach despite your fair skin. I used generously multiple times a day after my horrible burn and still had half a bottle left.

Highly recommend!!
I honestly cannot put words how much this stuff has helped my sunburn. It smells good, instantly make the burn feel better, and lasts a long time. If you need something, that’s a little bit better than aloe vera 10 out of 10 would recommend this one!!!

URGENT NOTE: Test in a small area first! Worked, but I'm covered in a rash from contact dermatitis.
You may want to test this stuff on a small area first before slathering it on. I had a bit of sunburn on my face and after showering, applied the gel and it worked great! Then.....contact dermatitis. My whole face blew up in a rash. Unfortunately, this didn't happen until the second day and I had already used the gel on my arms and legs as well. My face has cleared up, but the rest of me looks like I rolled around in poison ivy. I want to scratch my skin off. Pics don't do it justice. This is day 4 of the rash breaking out, so it's cleared up a little and I plan to borderline OD on benadryl this evening before I scratch my skin off. I wish I wasn't allergic, because it truly did work for my sunburn. I've not peeled at all and I was rather crispy.

This stuff works!
My wife and I just got back from Cancun and after being at the pool/beach for 6-8 hours every day, we ended up a little burned. We used sunscreen, but still ended up a bit burned. This stuff was a lifesaver! Took the sting out of the burn and after about a day the redness turned to tan. Definitely buy this!
