This is my 68 CU 3000 PSI Pure Engery HPA tank. I just recently bought it and have only used it once. I have no idea how this occured but there is now a scratch on the surface. Is this tank still in useable condition. I have used it onl;y once and that was after I found the scratch. It had no issues but I am wondering if it is still safe to use.
Here are some pictures:
