@Roadwarrior, Good luck with the sanding, can't wait to see you finish up one of your MK V castings. Hopefully the tut helps.
@Slideo, thnks man,The sculpted detail is still pretty rough right now, I'm going to tighten that up tonight. Also, I am going to try what Roadwarrior recommended and give my sander a good cleaning.
Keep building guys!
