I don't see ignition modules as being particularly picky about which heat-sink compound is used...as long as SOMETHING is used, and it isn't wheel-bearing grease.
There was a time when plain ol' silicone dielectric grease was suggested. I think we can do better now, but in a pinch...
Details, please. My Fluke 88 comes apart about twice a year to fix dim or non-functioning LCD segments. I've been rubbing the contacts with a plain ol' pencil eraser to clean them. It works for awhile.

I thought I had replied to you but I cant find it.
My fluke 87 looses segments about every 2 or 3 years or so and I use the pencil eraser fix too.
My military issue Fluke 27fm doesnt have that problem
My reason for using a silver based anti corrosive gel on my fluke is a twofold theory.
All of Western Washington is a hostile environmemt for electronics
Saltwater marine use is a bit beyond the design parameters for that 87 meter.
So I used silver anti corrosive on the 87
And I dont take it on boat trips anymore.
It has a lot of options and features that I will never use on a 12volt 120 gen boat.
My military issue fluke 27/fm is a brick.
Its about the size of a brick too.
If you see a 27/FM for sale
Not just a 27. It needs to be a 27/Fm
Buy it.
They dont have all of the features of the 87 88 range but the 27 is a durable rock solid field use brick.
They are getting to be hard to find.
You should try to find one while you can.
