Refinishing?????

[Gentry]

I have been working on refinishing a bow it has a cocbola riser and I keep getting these little milky white spots showing up in the finish they start to aper while drying then become more visable in the next two days none showed up on the limbs though. the first time I did it I put three coats of finish on it one every 20 min. the second time I thought I would try one light coat let it dry and go from there. I just got it all sanded down and ready for another shot but thought I would ask for some help first. I was using minwax indoor/outdoor helmsman spar urethane. anyone ever use this? should I be using something else? any tips or ideas?

Try the History/Collecting forum, those guys will definitely tell you how to do it.

Ill throw my 2 cents worth in.Ive refinished several bows that were in pretty bad shape and have had real good luck with tung oil and qaulity polyurithane finishes.I prefer tung oil but with it you cant leave any of the original finish on the bow becuse the tung oil will not penetrate it.
Its a lot more work but the end result turned out really well for me.Just a little something to chew on,good luck with your project.

I'm not a big typer..but go to the local bookstore and get a book on furniture refinishing. Check the contents for oily wood finising techniques...GREAT info from the best in the world from filling pores to taking care of issues like these.

Isn't cocabola an oily wood? I bet you need to wipe it down with acetone, then a sealer to seal the oil, then you can use your finish coats. I use minwax wipe on clear poly and have real good luck with it.

Cocobola is an oily wood and needs to be sealed with a quick drying lacquer.Or you can rub super glue on with a finger,with a rubber or latex glove.A polyurethene will not dry on an oily wood if not sealed first.

Humidity can be a issue with some finishes.  High humidity can cause a finish to "blush" or look foggy.
