If you are not racing and none of the gouges actually go through the P-Tex and into the core -- yeah you don't need to do anything -- scraping to remove any P-Tex hairs, hot waxing and edge tuning will improve things.
If you prefer to have smooth bases -- get a repair iron and P-Tex repair string from Tognar.com -- repairs with that basically good as new -- compared to the P-Tex candles that you light and drip which don't last very long.
