The good quality epoxy pytty

I found this very easy to use due ro easy instructions, as you only the amount required for use to be applied. Like the instructions say you have to knead the putty like working dough between your hands so that the outer darker area of is mixed with the inner lighter part of the putty to activate it before applyito to the surface area, but you must prepare the surface to with some sandpaper and clean it to make sure the putty has good surface to work with in the end. Once done it states it takes 8hrs for it to completely cure meaning you can even drill or sand it afterwards, if need be.I did find the i was able to shape it to plug the hole in pipe while while smearing it around the pipe, as to make sure it worked like a bandage to prevent tye potential of exhaust’s gas pressure being able to blow it anytime in the future. I wore rubber gloves while applying the putty with my hands which made it a lot easier to work seeing it can dry within 2hrs which means you can tell its just starting to thicken a little while still being mailable to continue shaping to surface area meantime.Remember, its up to 2hrs to drying but 8hrs to completely cure before being able to drill or sand it.

Excellent stuff. Long term review.

Had a small hole in our hall radiator. I was skeptical to tell the truth. Hallelujah, it actually worked. Sealed the hole, no problem. Over a year now since I did the repair. Still no leak. Once the putty sets, it goes rock hard. Handy stuff to have in the tool box.Highly recommended..

Easy repair for exhaust and bracket

Had to purchase this as during an inspection under my car I found the exhaust mounting bracket had broken away from the exhaust.So after making up a ball of this I applied it to the arm and exhaust, the adhesion was very good with no messiness. The bracket held to the exhaust and I left the vehicle to sit for a day and then took it for a long drive and checked the exhaust which was still held in place so this has good strength and durability. Hopefully this will last!

Good stuff

Used it to tidy up my welding on my exhaust it sets rock hard even without heat, easier to mix without gloves as long as you use plenty soap & water will use again if i get a stripped thread as it can be drilled & tapped. Delivery quick 48 hours.

Repaired middle silencer along seam

I used this on a middle silencer along the original weld seam which had split slightly and was causing it to blow.Firstly, I suggest you use a wire brush to remove any loose metal or rust. I also applied Hammerite Kurust rust converter to the area to prevent any rusting occurring behind the repair. This was left to fully dry.This product was kneaded together and then pressed into, on top of, and around the split, and then extended the entire length of the seam. This took an hour, but only because I wanted to make sure the putty was sealed up against the metal as best as possible.It was left to cure over night, and driven the next day.No more blowing that I could feel/hear.3 weeks later, the car passed MOT.I would say it's worth it before purchasing an entire new exhaust replacement.Finally, there is a slight smell which has faded over time. Others reporting of a strong smell must have it on a hotter component. On the middle or rear silencer, I would say there's very little smell after 3 weeks.
