This is what Troy told me
"If you can screw-up the massey finish I'd like to know how. I don't think it can be done. It's so simple it's unreal. Other than being time consuming there isn't any draw backs to it. Mix one part slow set (30 minute or more) epoxy to four parts acetone. Rub on a coat and let dry. If you can get to it between 6-8 hours you can rub on another coat without sanding. If time runs longer than that, you need to sand with 320 or finer sandpaper.
The super glue is what O.L. Adcock always used to seal cocobolo. He would rub on one coat, let it set for something like 20 minutes then light sand with 600 grit paper. After that he would apply another coat and then spray with fullerplast or thunderbird. It didn't fully fill the pores of the wood, but did make it where he could spray without problems.
I've always used the massey finish to seal any wood. I did use the Bullseye shellic sand and sealer on the last bow I built and have been told it will seal cocobolo. It's faster dry time really helps. One hour dry time and sand with 320 paper. I applied 7 coats in one day and the bow was ready to spray.

I struggled with it and gave up. Didn't have time to figure out what I was doing wrong. Haven't finished a bow since, so I may give it another try soon
