i guess i'll find out, as i ordered a couple of cans of that stuff. [as well as several other items that were on sale, so i ended up with free shipping, as well as $15.00 off my order]
wouldn't be the first time i threw money away on stuff that didn't work.
i have a set of TTI step headers someone trashed the primary pipes trying to get them to fit straight plug heads.
i'm almost done repairing the one side, and i plan on blasting them good from both ends having it done with an industrial blaster using a flexible hose down each tube.
good thing i got these pipes super cheap.
