This is not, has never been a bad batch. We had a few faulty syringes a while back, but that issue was the syringe itself and not the product inside i used two tubes from that batch with those syringes with no issues.
The issues you mentioned in your first thread have been seen before and I explained how your application technique should be modified in that thread. I also explained that you don't need to remove it because a light polish will remove the haze and still leave protection if you stop polishing when it clears up.
Hazing only happens for two reasons:
1. Excess product is allowed to dry
2. Excessive wiping with pressure after flashing occurs
Your first post also mentioned that it went on oily and wouldn't flash, which indicates something on the surface not allowing the coating to bond with the paint. I have a couple of videos and multiple threads here where I talk members thru application with more commentary than the provided instructions...what to watch for, when to wipe, how to fix, etc. just search my posts. I'd hate for you to give up on a great product before you even got to enjoy it, and I also don't want you to chaulk it up to a bad product and have the same thing happen again later. So, take a look at my videos and other posts and jump back in there!
