if you want to do it properly there is a whole rake of 'gear' that you need.
the treasure cove kit takes off some of the clearcoat,so i would only use it once on any machine.
this is the process I use. for the playfield. ramps are different ball of fish.
cleaning
isopropanol alcohol to clean, best source a chemist shop.
novus 2, 2 to 3 applications until no more dirt is lifted, ie clean cloths after wipe down. pinball heaven.
after cleaning sealing is most important,
autoglym super resin polish. this stuff adds shine and will fill imperfections in the
cc, work it into the p/f and let it dry polish out with cloth.

again 1 or 2 coats.
on to waxing
2 or 3 coats of a good liquid wax first
meguiars is what I use at the moment (do not buy the cleaner wax)

apply with a micro fibre cloth, 2-3 coats let it dry for 20 minutes before removal .
and then a paste wax

again atleast 2 coats and let it dry before removal. I use a 'sponge' applicator. always remove with a clean lint free cloth for best results.
yes, the process is long winded and some might say over the top, but if you do it properly it gives a mirror finish that you can see your face in that last for years. you will still get 'ball swirls' but these are removed by a simple wipe over, it's all about layers of protection, I will just add with this method I have won best in show 4 times at the big pinball do jab.
