Reliable and flexible gasket maker, saved me from buying a special gasket
I used the Visbella Neutral RTV gasket maker on a recent engine repair where the intake manifold was leaking and I didn't have the time to buy the proper gasket , and it worked perfectly. It’s easy to apply, bonds well to metal surfaces, and remains flexible after curing. It’s resistant to oil, water, and antifreeze, which gives me confidence that the seal will last. The 3 oz tube is just the right size for small to medium jobs. Pros: Easy to apply and smooth Oil, water, and antifreeze resistant Remains flexible after curing value for money as it will last for loads of little jobs and it is very strong Cons: Tube could be a little larger for bigger projects Overall, a high-quality, reliable gasket maker for DIY or professional use.

Pâte assez liquide et difficile à travailler

Super produit je m'en suis servi pour rendre étanche un boîtier plastique contenant de l'électronique très facile à appliquer et très facile à enlever une fois sec.

Utilisé pour un carter moteur. Problème, une fois durci le produit n'est pas d'une franche solidité, d'ou le risque pour les parties situées à l'intérieur du carter de tomber et aller boucher la crépine. J'attendais beaucoup du produit mais j'ai finalement été déçu. Donc démontage complet et recours à un joint bien classique en nitrile. Convient par contre pour des portées planes permettant de mettre très peu de produit et limiter le risque de pénétration à l'intérieur du moteur.
