I've always wondered if heat has a negative effect on the balls surface when polishing and heavy pressure.... I remember a guy at the old shop who would produce a lot of heat when he was polishing his equipment.....

If you need to produce the heat extremes that Juggernaut referred to, with that pro shop/driller, I think that ball may be either the wrong one for the job or it was drilled wrong.

Most balls just need to right grit level under the proposed polish to produce the reaction necessary, depending, of course, on whether it was the right ball in the first place and had the right or close-to-right drilling in the 2nd place. --- With all the options in place in today's bowling environment, between sandings and different abrasive pads and the huge range of polishes and compounds available, the right surface for any ball is relatively easy, simple and straightforward and should be accomplished in 1 or 2 attempts. ---- Again this predicated n the assumptions that the "right" ball was drilled the "right" way for the bowler and the oil/lane surface on which is bowling.
