one of the welds on my exhaust is half cracked around, it only opens up when the cars been running and the exhaust tubing is hot. I cant reweld it because I dont have a welder, I do have
JB Weld however. my plan is to just put a roll of it around the entire weld to seal and reinforce. right now the exhaust is warm, but not too hot to touch, the seam is open. should I seal it now like that ...
