If you sign up for their email list they will send you a 10% code for any purchase over $50. That's what I did when I bought my ceramic engine paint last week.
Good luck placing an order. I guess their warehouse burned down and destroyed a lot of inventory. I tried to place an order last week and they didn't even know what they had in stock.
I ordered my engine paint kit over a week ago. When I hadn't heard anything back, I saw my order was now back ordered? I called they said the were out of the mixing cups, so I told her to ship them without the cups. I still haven't received a tracking number or shipping confirmation?!?! New engine can't go back in the car til it's painted. I don't want to rattle can it so I ordered their high dollar ceramic paint. Now I'm stuck...
