I Am on my second sparky magnet protector which is also curling up

First one came of without damage, 2nd is still installed, curling is not to bad and to afraid to tear it off. Bought already goo gone so sooner or later it will come off

If I would have to do it again I would skip the magnet protector. Have no experience with hammerlock as I have a pro. The curling matters are to the best of my knowledge all related to the magnet, not to the hammer lock

Cliffy has always stated that his protectors are sacrifical. They are not meant to be permanently invulnerable protectors. Simple physics, you bash a heavy steel ball into a thin still ring, at the point of impact, it's going to cause a slight bend as the thinner metal deforms. That leads to it curling up over time and repeated impacts from the ball. I haven't used one on my pro, but I did have to use some Hard as Nails to help the playfield not wear as bad in one little spot where it was looking kinda bad.

On my Met Pro both of the magnet protectors curled up after a few months and had to be removed. No paint came up. I have put about 10 to 12 of these protectors on my machines over the past couple of years and I believe five have curled. However, I have several of his other protectors on my machines and they work great.

Only one of my magnet protectors pulled up just a little bit of paint.

Just put mylar around the magnet. Does just what you are looking for and won't tear up the area around the magnets.

Mylar on the cross and sparky cliffy on the coffin

Does the coffin magnet not cause the cliffys to warp?

My coffin magnet is, interestingly enough, the one that looks like the day it was installed. In the same time I have gone through three Sparkys.

No problems with coffin protector. The other two peeled up. You are better off wth Mylar for grave and sparky. For whatever reason the protectors will curl up.

I have the cliffy's on Sparky and Coffin. No problem there.

I would, however, be careful if using the eject cliffy. Caused my manual launch to go silly. See here: https://pinside.com/pinball/forum/topic/met-manual-ball-launch-not-going-str8-auto-launch-perfect

No problems with mine yet, cross fingers

Don't bother mine peeled as all will

same for me, and as said, its NOT permanent, quite logical to understand...

the only & good advice than : DONT play your MET anymore !!!

jokking of course, pinball are made to be played

I Read a tip on another thread, so, in case you haven't seen it.. Raise the magnet so it is flush with the Cliffy. I have done this and it seems to be helping a LOT. Makes a lot of sense.. When the ball bashes down on the inside of the ring there is no where for it to go.. The ball can only push down as far as the magnet. And if it is rolling over it there is now no "collision" with each edge of the ring.

I think I may have even read it on Cliffy 's site.

Seems to be doing the trick on mine as well. I've put a decent amount of play on my Cliffy rings, and they look brand new. If you've never adjusted a magnet core, it can be a bitch due to the huge nut held in place with loctite. I had already busted my nut (har har) to install Pinball Life's case-hardened magnet cores, so it was easier to adjust them.

How do you adjust these magnet cores? Why did you need pinballlifes case hardened magnet cores? Just curious as I was wondering what the maintenance is on the magnets, and how to take them out of Metallica?
