Used for interior car door handle repair job
I bought this for my husband to repair the interior car door handle on the driver side. The part he needed was hard to find and to take the car to be repaired would cost hundreds, this was decided on as a temporary solution. Next day delivery, inexpensive and easy to use, we can’t complain. It says you need protective gloves and clothes (but how much less are you going to make?). He tried gloves but it was easier to use bare handed - be quick to wash the putty off afterwards. He just kneaded the putty and smoothed a very small amount over the cracked plastic and held the handle in place for a couple of minutes. It cured after about 20 minutes. A few days of use in and out the car and the handle seems to be holding up. We may not need to get the spare part after all.

Not great for artwork
Will be too hard to work after about a minute, so you have to be quick. Not great for artwork.

Brick Hard
I used this for a repair to my golf trolley - I did the repair with the putty then painted over it with the epoxy - rock hard and lasted the whole golf season without any issues

Don't waste your time.
Total waste of time. I mixed it as per directions and put it on thick. I then left it 48 hours and it was still soft and came off when I was getting ready to sand.

This stuff really works!
So a really nice person kicked off the door mirror on my car (Nissan) causing it to hang by a few wires. The plastic mounting bracket had been snapped completely. According to Nissan, my only option was a complete new mirror at around £300. Or was it? With only a few centimetres of 'surface' I wanted to try sticking the mirror casing back onto the mount. But the mirror is heavy - it has a camera and electric motors behind the glass and I thought it would be too heavy to stay stuck with such limited surface area, particularly when the car would be bouncing on roads, driven at speed on motorways etc. So I found this product and tried it before spending big money. Nothing to lose, right? I used the putty on both edges, held it together for maybe 10 minutes and it bonded. So far so good. I then left the whole thing for 2 days (I know you don't have to leave it that long, but I didn't need the car) before screwing it all back together. I sanded and painted over the white/grey residue (black) and hoped for the best. I took it for a short test drive, fully expecting the mirror to fall over when I hit the first bump. That was 2 months ago. Absolutely perfect. Solid as a rock. Great product. And saved me £300.

Fantastic product if you know how to use it properly. Cures extremely hard and bonds to plastic well. Its a little messy to use, but it is manageable when using gloves. I used it to fix my car's wind deflector which shattered into several pieces, some of which were missing. After sanding and painting, I tlreally cant tell the difference between the putty and the original parts. Its a bit overpriced for such a small amount, but it did what I needed it to do.

I wanted to thank you for resending the above order. I received the package in good order. Thank you very much for the excellent service. Goede aftersales contact met verkoper, eerste pakketje was zoek geraakt waarna verkoper me een direct een nieuwe heeft toegestuurd. Prima service van die bedrijf.

It hardened and becomes part of the broken material. Used on my cracked luggage. Works perfectly.
