Holts Gun Gum Exhaust Paste, Exhaust Repair Paste, Professional Quality Exhaust Sealant Paste To Create Gas Tight Seal & Stop Leaks, Reliable & Easy To Use For Fast Permanent Exhaust Repair, 200g

Worked really well... follow instructions and all should be fine.

Easy to use and effective.

Described as it is, value for money, arrived in good condition,

Very easy to use. It’s sticky and flexible and easy to cover over any cracks. Expect to use a lot. I needed to cover a crack (and used about 3/4 of the tub) and though it’s easy to work with it takes a bit of time to make a good job patching things up as it’s sticky. Once it’s on you MUST let it set which will take at least 24 hours left alone or it will just fall apart. You can speed the drying process up by running the engine low to heat up the exhaust as the heat will harden it but any revving etc will ruin all your efforts and you will need to get another tub. Time and patience is the secret to making this work. After a month or so the hard formed gum around the crack started to crack and get brittle itself but maybe it’s because it’s on a Harley Davidson exhaust which vibrates a lot? So I’m not sure if it’s great for long term use but it helped me short term until I replaced my exhaust. I would buy again if I needed to but will have gloves and baby wipes close by.

Brilliant stuff

Did tell job great 👍, easy to use ,

There are better products on the market. Messy to use and flakes off after time. Alright for short time repairs

Does what it says, good paste no leaks or issues

سيئ جدا ومنتهي الصلاحية يأتي على شكل معحون متحجر غير قابل للاستخدام

I’ve used JB weld and pretty much everything that is used for exhaust repair and it all fails and breaks down. This has fiberglass in it making way stronger and keeps a nice tight air seal. I recommend this to anyone having exhaust issues. I’m using it to seal manifold gaskets since I don’t want to tap all these broke bolts yet. Works great, it’s a must have.

Il prodotto resiste bene al calore della marmitta a differenza di altri che non c'e la fanno. Ovviamente bisogna saper stuccare e dargli i giusti punti di appoggio altrimenti a lungo andare rischia di staccarsi, ma in ogni caso il calore non lo danneggia.

El silenciador de la moto estaba rajado por su unión unos 20 cm de largo por 1 cm de ancho en algun punto y con óxido, lo lije todo y le aplique una capa tapando y penetrando en toda la raja, mientras corte una plancha fina que tenia perforada y le puse a modo de refuerzo y con celo industrial por el lado que no engancha lo envolví y deje secar 12 horas. Mi sorpresa fue que cuando empece a sacar el celo no estava muy seco, por lo que decidi poner otra vez celo y con la pistola de aire caliente empece a darle y mi sorpresa fue que empezo a quedar duro como una piedra. una vez seco le di otra mano de GunGum para tapar del todo la plancha y otra vez aire caliente y en 10 minutos estaba seco y duro como una roca. Aconsejo darle calor ya que en un momento esta seco.

J'avais plusieurs trous dans mon silencieux de la taille d'une pièce de 2 euros environ . Une fois rebouché avec la pâte , la fuite a été colmaté , j'ai passé le contrôle technique sans avoir de défaut pour l'échappement et pollution. Par contre la pâte est dure à mettre et filandreuse, sa fait pas du boulot super propre, sa ressemble plus à de l'étalage de choucroute, mais bon... Sous la voiture on le voit pas.
