Way exceeded expectations

I purchased this in rattle can form and didn't expect anything too special from that method of delivery but figured why not try. I can say I can't paint worth a damn, everything usually comes out streaky and uneven when I paint. This sprayed so we'll and layered beautifully I was amazed. It looks like it was professionally sprayed by a competent painter. I bought 6 cans anticipating needing it all and it was done with 3. I'll never buy paint anywhere else again. Extremely high quality. Couldn't ask for a single improvement on what I received.

Sunburn Metal Flake
Brian Bucenell

Sprayed this flake in clear coat over a black base and it made the black POP! in low light or at certain angles, still looks black but when you get the right angle or direct light, it gives it a black cherry look! Absolutely love how this project turned out!

LUV it

Exceeded my expectations price was great caught her during the Easter sale having fun with it can't wait to purchase more things from the company.

Amazing color

Abyss Black is one of the darkest black paints I have ever sprayed. Great coverage and went a long way. used it under the interstellar blue pearl and looks amazing.

Easy use spray can. Looks good. Shipping however is a little to be desired. FedEx should be used for shipping. UPS has a lot of issues.
