Honestly mate, I put some coilovers on my car, put three thick runs of copper grease down them, winded adjusters up and down to spread it, wiped a load more on and then used and abused the car, mum used it for 4 months and was never really cleaned etc, sat for ages, I got it back, wiped the grease off the coils and they were like new. Adjusted no worries.
Coat them in copper grease and then put ya cover on. Top job!
