Efficace !
Alors oui ca coute un bras mais c'est vraiment efficace pour le coup. Utilisé pour colmater un trou dans mon silencieux intermédiaire sur une Golf, juste frotté un peu avec une brosse sur la visseuse et soudé une plaque vite fait avec un mig et j'ai tout rebouché au JB Weld. Il faut juste attendre un peu que ca prenne et laisser chauffer pour que ca se solidifie. on peut aider avec un décapeur thermique mais si le temps est sec on peut juste le laisser quelques heures voire la nuit et le lendemain ca aura pris et ce sera étanche, j'ai économisé 400 balles

Used on 3in 94 k1500 exhaust, worked great. 350sbc
Worked great for my application however, it cracks on moving joints. Still sealed my exhaust very nicely.
