The Bow Hospital is a sponsor here and they're well recommended. If you're shipping out that's a good place to go. Rich Lopez (droptine59) does a great job and his website has lots of tips if you decide to do your own
http://www.droptinetraditions.com/php/ Rich and Nick McDade (tuscarawasbowman here on Tradgang) have given a lot of tradgangers a lot of help on refinishing tips for us do it yourselfers on the History/Collecting forum here. So that said, if you've got some time, patience and ability to follow directions, you could redo a bow yourself. I did (followed the bow restoration 101 document, see Tradgang History/Collecting forum) and I'm more than pleased with the results.
Here's the prefinish version of my 1971 Super K. Note the yellowed finish color and the spot where the old stick on rest I peeled off from the Berger Button hole had removed the bow finish.
and here's the finished version
Here's the refinished front view with new decal in place. If I had a prefinished picture, you'd be able to see how much the white glass on the riser overlay had yellowed. It's amazing how much different it is. I used a wipe on satin polyurethene as I don't have a fancy spraygun, but I'm very pleased with the results. Everything I encountered is addressed in the bow restoration topic or topics on droptinetraditions site with pictures and easy to follow instructions.
This was not a straight refinish job. It included removing an ill placed Berger button insert and plugging that hole. The new rest plate on the bow covers the hole on one side and the new coin (which was half drilled away by the Berger Button hole) covered part of the plug on the back. Bear coins are availible from 3 Rivers and decals are availible from a reference on Droptinetraditions website from Al Harford. This project took me about 20 hours and there was a learning curve, but I'm so pleased with my finished product (I'm a 10 thumbed accounting person with little do-it-yourself building talent). The only mistake I made was taking a picture of the serial number and bow specs and using a blown up copy to reink on the refinished bow. My final print came out larger than the original and I didn't notice till I looked at comparison pictures.
Here's the results-a spike buck taken from the ground in the Michigan late bow season.
So if you're shipping out, contact the Bow Hospital (sponsor support). If it's a unique bow (59 Kodiak needing special attention) I'd say Rich Lopez at droptinetradition. If you're feeling adventuresome-do it yourself!
