What do you think?

Looked it up on their website, but no mention.

Looked up Wiki article, and they say contents are 15% mineral oil, the rest solvent and propellant.
There's no silicon.

Might be very handy

Hi Tom,

I think I would be concerned about the "solvents" part of that formula. If it's mineral oil you need, why not use just mineral oil?

Hi Ned:

The solvent, according to Wikipedia, is mineral spirits or naptha.

I've used mineral oil and it's a little thick. It's needs thinning anyway. The convenience appeals to me.

I just wondered if anyone has ever tried it.

By the way, I don't use lacquer, only varnish, KTM or shellac, depending on the job. With shellac and varnish I rub out with water and soap. With KTM, water works well unless I'm in a hurry.

Thanks again,

The purpose of the liquid used in wet sanding is not lubrication. After all, you are trying to wear away the surface; why lubricate things and slow that down, unless you just want more exercise. The liquid (my favorite for lacquer is paint thinner) serves to keep the particles suspended so the paper doesn't clog.

I suspect WD-40 would just slow down the process and make a mess.

You're right.
I stand corrected (can't sit)



For nitrocellulose I use water with a little dishwashing detergent added to hold and disperse the slurry - it prevents piling (the little balls of lacquer that form with dry sanding) and definitely improved my finish standards. But, water can be a real pain if you have any bare wood exposed (screw holes and bridge ferrule bores in electrics are a good case) and will swell and split the lacquer in the vicinity. I recall other makers use white spirits/mineral spirits for rub out and have very good results from this with out the problem of water.
As a lacquer user I wood not be caught dead spraying W-D 40 in my shop. If you are looking for trouble thats the stuff to use.I sprayed some on a bolt I was trying to get out one day and I had a lot of fish eye in my finish for a long time after. I use Kerosene for my liquid when sanding the finish. Bill."""""""""
