NO instruction provided for this toxic material. NO proportion to mix two components, NO drying time provided either and you dont know how long you left to work with this until it settles. You have to gues or experiment on your own risk.

Product did what it says on the tin and was straightforward to use. Main issue was in judging the amount of hardener required for small jobs. A disadvantage is that the instruction sheet needs to be downloaded from the web-site.

Works well

Seems to have worked well but time will tell. It does set quickly and there doesn’t seem to have enough reactor for the big tin but you don’t need much

Really strong repair

Great metal filler, I had to repair a small hole in my car subframe and this was ideal. I thoroughly cleaned the area of loose rust and degreased the area the filler was easily to apply and once it had hardened I sanded it down) (tip try and build up layers rather then a big dollop) it was very hard and once painted and rust proofed it was a solid repair.
