For chrome paint I use "Alclad II".
A lot of people swear by "Spaz Stix".
Keep in mind, you will never get a true chrome finish with these paints.
You'll get much better results sending out your parts for replating.
Most times, better than original kit chrome.
As far as markers go, the new "Molotow" chrome markers give an excelent chrome finish for small parts, but it's very fragile & highly prone to dulling with any handling.
In this case you're much better off putting in a little practice time & using "Bare Metal Foil" for body trim.
I have kits that were foiled 25 years ago that look as good as they did the day that I foiled them.
