I have been researching methods to rub out a high gloss finish. Most methods I have found use pumice and rottenstone or sandpaper. However I found this video.

Here he is using automotive products to achieve the same results. Has anyone tried this method? I’m looking for first hand opinions on if this method is as good as the others.

These products are readily available to me locally and I wouldn’t have to order anything.
Thanks Dean

Any film finish can be rubbed out to its maximum inherent gloss, but it’s obviously best to start with the one with highest gloss, like CAB acrylic lacquer.

1. Wet sand with successive grits to 600 to flatten the surface.
2. Use auto rubbing compound by hand or power to eliminate sanding scratches.
3. Finish with auto polishing compound, preferably with a powered lamb’s wool bonnet.

That’s the method I have used for most of my projects posted here. Main thing is to apply several coats and let each coat dry for a few days or more. Once you have the final coat on, wait a week or more if it is cold and then do the wet sanding. Final sanding can go up to 3000 before using quality compound and polish.

Charles Neil, who sometimes posts here, has some videos on the net which detail how to rub out a finish. You can find them on youtube

I didn’t check your video, but I do keep a can of both automotive rubbing compounds well as the polishing compound in the shop. They work well on a well cured finish to really smooth it out. They are also useful for small rust spots and stains on cast iron.

The important thing that Clint touched on is your choice of finish. Don’t try to rub out poly to a high gloss. It’s like trying to polish a tire. You have to start with a very hard surface.

Personally I prefer Tripoli grade rottenstone to rub out lacquer. When I am going for extreme gloss (80+ on the scale) I will just french polish. Something with extreme gloss shouldn’t really be handled often anyway so I don’t require any more protection than shellac affords me

Thanks for all the replies and suggestions.
Good info from both Mr. Neil & Mr. Whisperer. Thanks for the links to the videos. I am going to try with the automotive products and see how it works out. I am finishing a project guitar body for myself so if if doesn’t work so well I can always strip it down and start over with sandpaper. ;)

BTW, I have an old porter cable ROS I bought to use to wax my car. It has a hook and loop holder, and you can get buffing pads with fuzzy backs for hook and loop. Some companies used to rebadge the PC ROS, markup the price, and sell it as a car buffer.
So, I would use a ROS instead of the drill the guy uses in the video.

Never used that setup for wood, but I did use some liquid rubbing compound and my ROS to buff out a piece of fiberglass and it worked very well. Put a nice shine on the fiberglass.
