Anyone customised their own clubs?

Have paintfilled a number of sets in the past, along with my Scotty putter. Really simple to do, Nail varnish remover to remove old paint, or excess paint when refilling. Acrylic paint or model paint to fill. Dont' be shy in filling, don't worry about being neat. Just use the varnish remover on a bit of kitchen paper to wipe over when dry to remove any excess.
