Be careful when adding hardener but a great product
It arrived on time and the best packing you could ask for. The product is extremely good but, you need to be careful how much you mix in one go and do not add to much hardener. If you add to much hardener the mixture will go grainy and once this happens you need to throw it away and start again. If you mix to much you will not be able to use it before it’s starts to harden.

On the fence with this.
Not the easiest of products to work with - tin is awkward to get contents out and the only sensible place to mix with hardener is inside the lid. Yes it dries very hard and so far so good prior to rubbing down but I ended up in a right mess - use cheap throw away tools for applying filler and wear disposable gloves. It may have been simpler for me to buy a new door as I had quite a bit of wet rot and a couple of deep holes so needed 2 x tins - suppose it saved the cost of a door, fitting locks and hinges so all in all worth the money and effort. Time will tell.

Excellent
Worked well on external wood surface. You have to mix with the hardener supplied and use quickly before it dries. But sticks to surface well and easy to layer up. Dried well and withstood a lot of heavy rain before being able to paint over it

Car body filler for wood.
This stuff is great, it's really car body filler, least it smells the same. Don't mix too much, it goes off quick, best to do small batches to save waste. Sands extremely smooth, doesn't dink like traditional fillers. Highly recommend.

Easy to finish off
It is a very smooth and white product which, when cured is smoothed or shaped with a rasp, chisel, or abrasive paper etc.
