Nope. Never had anyone confused on my use of the word. Here's my point:
(Not to pick on your method of fixing your dash, because in use it works perfect for your needs)
If you read an ad online for a Datsun and one of the details was "restored dash and door panels." What would you expect when you showed up to make a purchase? You'd expect factory condition pieces. I would be extremely upset if I showed up and the dash was covered in Shoe Goo and boot polish. In addition to that I'd be upset if it was recovered in vinyl or leather or really anything that wasn't the stock looking pad.
I'm not saying any of the methods are wrong, just not restored.
But all this is off point for OP. There are plenty of good options now mentioned for him to fix his dash pad.
Good luck!
