Thanks for the resposes,
What is considered a bad gouge? I just took a look at my board and I have one gouge that is 2 inches long, half inch wide and gradually gets deeper into my base to about 1-2 cm deep. Another gouge is fairly superficial but it literally goes the length of my board
Thats definitely worth it to ptex(the cm deep scratch). If you have the option, the black p tex generally seems to look nicer after than the clear IMO, depending on the color of your board too.
