What's good everyone. Are Blue Devil Stop Leaks really as advertised where its a "permanent" seal or is it pretty much like some Bars Leak products where its a temporary fix until whatever is wrong gets replaced? I was lookin at one of their bottles the one that's a Radiator and Block Sealer and I see on the bottle where it says Permanent Repair Guaranteed and I thought hmmm... is Blue Devil really a "permanent" repair or is it the other way around where its a temporary?
This is only a temporary fix. Any one can say they guarantee something but in reality how do they back this supposed guarantee.
See below: it’s temporary and a band-aid at best.

I missed the other half: guaranteed... or what? Will they replace your engine?
Oh nah
