Great “plastic maker”.
Bought it to repair the windshield pillar on my car. After mixing the product it takes around 20 to 30 minutes to start becoming harder. After an hour it hardens and it has a little rubbery texture. I sanded it and painted it afterwards, great result and easy to use.

Dried out and most likely expired.
This horrible glue had to be picked out because it had dried (white component of the glue). At first I thought it was a little, but I had to disassemble the syringe to get it. And in the end, having mixed it in the right proportion, after 48 hours the glue remained like rubber and did not glue securely, what I needed. I did not find the date of manufacture on the packaging, but this is clearly an expired product. This is a complete disrespect for the consumer, China even writes the date of manufacture and expiration date. Stay away from this brand and seller.
