I could tell you but then I'd have to kill you.
How 'bout I give you a hint & just slap you around a little.
Boy works part time at LineX so he got it done for the cost of materials.
If you were to do all the prep yourself, the cost would probably be about $300 for black. Color would run you a bit more. Most of the labor is in the prep.
Besides, it was a Christmas present so I'm not allowed to know how much they (Boy & Bren) paid for it.
