Hi Raptor,
Some people use white model airplane dope, some use a white grease pencil and some use a product called laquer stick..it is available from most dealers or from Brownells.
One thing you should know is that you need to prepare the metal surface first. I recommend you swab it with some isopropyl alcohol or a degreasing solvent and permit it to dry before applying the mark filling material. I also use a blow hairdryer to raise the temperature of the metal so that the fill material "flows" better into the no0ks and crannies. Afterwards, I let the stuff "cure" over night and then ise a sharp bamboo skewer to remove any excess. When done, a quick wipe with a cloth containing some Renaissance wax to replace any surface protectant that may have been removed by the process.
Hope this helps,
Tom A
