Compound in grain
Apr 23rd, 2016 at 9:04pm
 
I have finished a bowl with wipe on poly and then buffed it with super fine polishing compound. I got a great finish but I was left with compound in the open grain. Now I have this nice finish with fine white streaks. What is the best way to clean it out of the grain or maybe I can not.
Thank you

Naptha is commonly cited for removing wax.  If the binder in the polishing compound is wax . . .  I've never seen a suggestion that naptha can damage a cured finish otherwise.

I've no experience with buffing compounds.

With certain types of woods, notably black walnut, this is a common complaint with the white compound.  The usual method is to avoid the use of the white compound with those woods. The red compound doesn't seem to have the issue, probably mostly because the darker red blends into the darker color of the wood.

Once the wood has the white in the grain, you might be lucky enough to be able to wipe or scrub it out - otherwise, you can sand it down to bare wood and start over.

A photo would be helpful but typically a tooth brush usually does the job.

while your experience is accidental, i've seen some truly spectacular results done in ash and oak, where they ebonized it, then used light colored filler to deliberately infill the open pores....the results were spectacular.....I started having all sorts of ideas for walnut, ash , etc....any wood with large open grain....

I finally solved my problem by resanding and applying a water based finish. I thinned it 30% which helped a lot. I used that primarily because of the faster drying time. I then used 3M polishing sheets after each coat. Ended up with a nice glossy, but not too glossy, finish.
Thanks all again for your input.

Hi Bruce - glad you got your problem solved.

You mentioned you used 3M Polishing Sheets after each coat - not familiar with this product and would appreciate any additional info you can provide.

Thanks - Dave G.
