is it neccesary?

If using laquer, get yourself a piece of 1" emt from the electrical section of your local hardware store. Its a metal electrical pipe. Pretty inexpensive, come in 10" sticks and laquer wont break them down like it can to pvc.

I finished staining and sealing the shafts. I am very impressed with the Wipe on poly. I haven't fletched and shot yet but the sealer was not too shiny and seemed to be tough.
thanks

Regular Minwax Fast Dry oil base Polyurethane can be wiped on straight from the can.  You may not get the same gloss on the finish as a dip, but it will be just as tough.  Use the Gloss, it is a tougher finish than the semi gloss or satin.  Lightly sand or steel wool between coats; three will be enough.  Stain first with an oil base stain or alcohol base dye and let dry at least overnight.  Steel wool before the first coat of poly.

I think the reason folks don't like dip tubes is the set up time, and the mess involved.
As with anything the we do, preparation is the key.
Take the time to do the set up, have your arrows ready, and go for it.
My first flemish twist wasn't perfect, and neither was my first attempt at dipping.
Keep at it, develope a system, and the results will surprise you.
Have fun!
