Not worth
It is not worth a cent. Several attempts to stick the plastic, with the instructions sold, did not stick, I do not recommend buying it

Don't buy.
Mixed exactly has required and still like plasticine 3 days later, gave up and peeled it off... came off easy although the area had previously been thoroughly degreased and wiped down with an IPA solution to ensure no contamination was remaining.... I won't recommend it.

2液硬化でプラスチックの様に硬くなり削ることもできます。曲げ力より引っ張り力には強そうです。車のパネル接着に使用している接着剤に似ています。白と黒を練り合わせるので色はダークグレーになります。 熱で硬化が促進されます。

Used this on a metal coat rack to glue the pole-pieces together. Works fantastic and didn't need much product.

Fast delivery, Product says it contains steel in the glu. I can vouch for that, as I used this to glu magnets together and the excess wouldn’t wipe off after sanding, it just kept moving around. The steel powder leftover is some form of steel. Seems to be very strong, but not tested long enough.

Excellent glue Works well on my broken Abigail Ahern pelican lamp that had broken in transit Super easy and sets quickly make sure to hold the men’s with light masking type tape until it’s set enough to take tape off Break has held strong. Be aware it is black and I really needed grey but I didn’t notice this when purchasing so I’ll just have to paint over the join
