What is the gram weight of paint crown dipping and cresting on an arrow. Of a wrap?
Not much. I found the whole mess: nock, fletch and finish to weigh about 30 grains. Crown and crest would be a portion of that but likely around 5-7 grains. It would also depend on how much crown and crest was applied and the type of paint used. I'll let you do the conversion from grains to grams.
I have found 10-15grs w/ my methods.
For me with a spray " dip " and testors cresting. About 6 grn. Wraps can be up to 20 grn depending on size .
I always crown dipped with Bohning but never weighed the arrows afterwards to see how much weight it added. All I know it never made a bit of difference in the flight of any of my arrows...both wood and aluminum.
I weighed one set I did and it added about 13 grains. That would be give or take depending on coats used and thickness I imagine as well.
With a water based poly unthinned I was getting about 10 gns per dip. I have now switched to Pro Fin and it is less than half. With Tru oil it is about 5 gns for 3 coats.
For my arrows, one coat of stain, three or four coats of Tung oil, Sharpie crest, fletching, and nock... total about 25 grains. Would add another 15 or 20 if I seal with water based poly.
