“I found Martinez Metals on google and had them weld some stainless steel exhaust parts for me. Welds came out solid and pricing is super fair for the quality of work performed. I will be coming back again!”
“Had to weld a 360 crack on a cast iron exhaust manifold for my Toyota to pass smog check. They took time out of their day to help my somewhat urgent request, seeing as my car was out of commission, and they did. My car passed the smog check the second time after getting the cast iron exhaust manifold welded. Thanks Martinez! You guys are awesome.”
