I've been slowly going through my car disassembling all the mechanisms, cleaning and re-greasing all the 23 year old linkages, latches, hinges, and dodads, basically anything that moves and rubs against another piece of metal and should be cleaned and have a coating of grease applied. The problem is many things can not be disassembled to apply a thick grease to the pivoting parts. In the past I have tried pushing the grease in with my fingers, with limited success, or giving up and just oiling the part knowing that in a short time the oil will migrate out attract dust and dirt and the part will need lubricating again. Well, boys and girls no more! I have discovered a magic elixir: Wurth HHS-K.



Why HHS-K? Because it is compatible with rubber and plastic. But, most importantly this is magical stuff. It sprays on like a penetrating oil creeps into all the nooks, cracks, and crannies and then turns into a very thick tenacious grease. Just a word of caution, wear gloves when you use it. If you get it on your hands it quickly spreads, gets all over your fingers and then turns into grease; you might as well just stick your fingers in a tub of wheel bearing grease and try to work on your car, you'll need orange hand cleaner to get it off.
Here is a video of the stuff

 

 

I purchased the HSS-K from this ebay site. Although his site information is wrong. HSS-Plus was replaced by HSS-K in 2015. The HSS-K is the low VOC version of HSS-Plus. This ebay site has the right information but it will cost you $3 more.
