Easily as good as the more expensive brands.
I have always been an isopon fan but thought I would try this after reading reviews and because of the value for money difference. This has done an amazing job, used to rebuild 3 35mm diameter holes that were cut from a panel to fit air grills, just meshed across the back and applied this filler, came back when dry and hit it with the sander, usual finishing with the wet n dry and sprayed with the usual filler primer and I was left with the perfect finish for spraying. The hardened product is strong, adheres really well, sands very nicely and is really nice when finished with fine wet n dry before spraying. Very highly recommend for anyone into auto or metal cabinet repairs etc. A really good bridger and filler at a very good balance of value for money.

Very effective
Used to patch rust affected wheel arch on my car. Hardens quickly within about 10 minutes so use small amounts frequently. Very pleased with the product.

Good stuff
Easy use and drying within minutes so better perhaps not to mix too much all at once

Sets very quickly
This is great stuff, but at first it was a bit frustrating to use. Do NOT mix more than you need. This stuff sets in less than 5 minutes. It's not clear on the tin at all. Also, the mix ratio is unclear. It says to mix the catalyst at 50/50 ratio, but is that by weight or volume? If by weight, there is no indication of the weight of either substance. The tube says 15g but I think that includes the weight of the tube itself. And again, there is no indication of the volume of either.

Filled a huge hole in my van
Used to fill the rim on my van, found it very easy to use, sets hard (used in 15degree weather so as not to set to fast and allow malleability until I was finished). You only need a small amount of hardener. I divided the mixture into 4 and only took out 1/4, mix with hardener and apply, repeat process until done. Sets solids (left it two days) then sanded back with some sand paper. Make sure you wear gloves and a mask (I actually used two masks) very strong smelling and you don’t want to breathe this stuff in or get it on your skin. Happy with results for first time using anything like this, good value, great adhesion. Would definitely use again
