Thought rust converter was snake oil until my neighbor quoted me $900 for a patch panel
I always figured rust converter was just a lazy shortcut for guys who didn't want to cut and weld, and I'd been telling people that for years. Then a neighbor down the street got a quote of $900 to fix the lower rear quarter on his 68 Chevelle, and he asked me if the $24 bottle of converter was worth trying first. I told him to save his money, but he did it anyway and let it sit a week before priming. About four months later I was under that car helping him with brake lines and the treated spots were still solid, no bubbling, no creeping orange coming back through. It hit me that not every panel needs a full cut and patch, and for a driver car that sees rain and Ohio winters, a $24 fix that buys you years is not lazy, it's smart. Now I'm wondering if I've been costing people money by being stubborn. Has anyone here run converter on a car and checked it again after a couple seasons? Curious how it held up for you.
Four months is nothing, that car hasn't seen a full winter cycle yet let alone a few years of road salt soaking into whatever pinholes the converter couldn't reach. Converter works fine on surface flash rust but the second there's real rot behind it you're just painting over a hole that's still growing from the inside. Your neighbor got lucky, check that same panel after two Ohio winters and tell me if it's still solid.
