Wax free, solvent free polishing compound ?
Gents,
I am doing some polishing work that then requires me to use a hot blue finish. Any sort of wax residue will compromise the hot blue process. Brownells, in the USA sells a wax free polish http://www.brownells.com/gunsmith-to...--prod543.aspx
Does anyone know of a local product or source I can use instead of ordering from the US ?
Thanks,
Mike

Many polishing compouds, both cheap and expensive ones, contain as the abrasive agent lava pumice. A well known example is Brasso. But its also used in car polish and even in ceramic cooktop polish and airplane acrylic window polish..... Of course always mixed with some sort of more or less nice smelling solvent and wax mixtures to justify the price.
So if you are just after the abrasive component, it's pumice. Obtained from finely grinding lava rock. Now, where can you nowdays buy pumice powder in small quantities, I do not know. By the way, when applying pumice the fine granules break down ever further, become smaller the longer you rub. So the longer you rub, the finer the polish result gets.
What about scouring powder (remember the white Ajax powder?) coud that do your job? Contains no solvents or waxes or oils, but it contains detergents/soaps.

There are a range of polishing compounds for automotive paint - they'd certainly be wax free, and the only sort of solvent is either water or something ammonia based (by the smell of them anyway). Ask in an automotive paint trade store, I'm sure they'd have something.
Ubueat sells pure rottenstone/tripoli powder.

Pumice powder is used in the traditional shellac finishes. I'm sure you can buy a small bag of it somewhere.
I normally use #0000 steel wool when I'm doing and cold bluing.... I can't say I'm good at it! Decent results but never mind blowing. Hot bluing is a different is in a different league all together..
Have you got a tip to share?

If you don't have a very large area to polish these will do a great job and leave no residue.

Both Pumice and Rottenstone are available from the Woodworks Tool & Book Company in Sydney. Either product should do the job you're looking at.

Several years ago, NASA found the best polish for aluminium (for airplanes to reduce wind resistance and improve fuel consumption) was India ink. I believe it's water based, so should clean up readily.

Eskimo yep it's one of many products used for different effects...from memory anyway when I did a bit of searching on the topic a lot of years ago. Exactly where it was used in the process.. Well that was forgotten a long time ago. At a guess it can be used as an abrasive to cut back the shelac, maybe as a filler... Maybe not. Or maybe it was used in the burnt shelac finish..
I did a quick search on it before I posted to make sure I remembered correctly...
Actually, If I'm going to post it up, I should do the search!
It is used to fill pores

Their was an article I read years ago on a cracked, burnt on shelac finish that they used a lambs wool buffer at high speed. I think they used pumice to create a bit of friction/heat to help the finish flash off faster.
