Waste of money
I recently purchased a product for my exhaust system, as there was some leakage around the joint. Despite following the instructions carefully, the paste came out within an hour of application. Additionally, after just two days, there's no sign of the product I previously applied. Based on my experience, I strongly advise "don't buy it"

It Works, Over 1yr still in place!
I wish I had pictures of the patch my husband made on the tailpipe. He said it was super easy to use (easier than j.b. weld which he loves). I bought it about two yrs ago thinking it was only one and when I received it,(12 deep!) I laughed a bit and shrugged, the hubs chuckled and said we'd use it. We have and by "we" I mean "he" ... it made a huge difference on the above mentioned repair, it has lasted over a year now, no joke, what was supposed to be a temporary fix became semi-permanent! "What!?!? That can't be true" you might be saying but I'm here to set the record straight...it IS true! Long lasting, easy to use, obviously thick and stays where its placed, what more could one ask for...maybe a husband who is very handy.

Calidad mala
No cumple con la función de ser pegado y como vi algunos vídeos de YouTube decían que era bastante bueno pero como dicen en un vídeo y dicen en las instrucciones el sitio donde va la pasta tene que estar limpio pones está bastante limpio le pase un cepillo de púas de acero y luego puse agua y luego la pasta lo dejé secar 24h y luego puse en marcha el motor y en el escape se salió denuevo el agujero y un agujero pequeño aparte se hace como pompa parece chicle no lo recomiendo aparte no es soldadura en frío y no alcanza 2000 grados sino alcanza 110 grados y ya no sirve no lo recomiendo
