I just drill slightly undersized holes and pound in bb's. For instance the last prop I balanced took 4 bb's to balance the hub. Using masking tape you can find out how many bb's it'll take before you drill and then you can lay them out nice and neat beforehand. Oh yeah, drop in some CA before you pound in the bb's.

Personally I always balance the hub first. Once the prop hangs dead-on vertical I then proceed spraying on Defthane Clearwood Finish Gloss Lacquer on the light blade till perfect balance is achieved.

For that custom look I prime with white paint and color the tips, put on custom vinyl graphics and then use Nason Clearcoat to seal and balance. Props look better than Bielas and cost a whole lot less. I put my balance rod on, spray, check for balance, spray, recheck until balanced. This is all done AFTER hub balancing.
