OK, and the bottle I sent you obviously was not shaken either before I packaged it. Given the feedback, I will no longer suggest that the products be mixed. Having said that, I will continue to mix mine as I've never had any issues and will continue to use it as I have.
(I only replied to the thread because I thought you'd get a chuckle out of my story and to verify what the op had witnessed, not because I had concerns.)
I really can't see that it would make a difference if you shook the bottle or not considering it will get shaken around in transit.
Even though there were vapors coming from the bottle after the pop I can't validate if it was the chemicals being mixed or not...since I already knew before this thread that DG had already recommended for you to mix products...but rather the cause could simply come from a temperature fluctuation resulting in pressure build up. I can't validate that claim, but I can make a comparison...
...I can take an empty 16oz.-20oz. water bottle, twist the bottle almost to the point of bursting, spin the cap off and it too will pop. I can then hold the empty, and popped, water bottle in the air only to see vapors arising from it as well. So that point I made about the vapors wasn't meant to seem like a big deal.
the exploding or popping of the product is not so extreme that you should stop suggesting it! imo
the product works great! it people are worried about the popping, then only mix what u will use on each application. i think it is just a matter or the air expanding in the bottle. no if people are opening the cap with it aimed to their eye...well, that is just stupid. i always open the cap facing away from myself, the vehicle, or anything i dont want to get a little outacontrol spray on.
501/601 is STILL a great product! mix on my friend!!!
I agree that I wouldn't stop using it, or stop suggesting to mix the products. Especially since the mixing information was recommended to Richy by DG. I would think DG would know if there's any major concerns when mixing.
The popping didn't really scare me because I figured some pressure had built up since the lid was a bit hard to unscrew. I assumed it could have been from air pressure changes from transit.
It's always a good practice to open things away from your face, however, it's no garuntee that a mist or vapor won't still reach your eyes. It's traveling fast when it pops like that. I didn't think anything about it after the fact until this post. It was no big deal then, and it's no big deal now.
My bottle has been stored in the garage with fluctuating temperatures since it arrived, with the red seal in tact and inside the screw on cap. There has been absolutely no pressure, or gas issues since first opening the product and I still can't wait to use it. One more day of class on Thursday and it's time to give this stuff a try. I can't wait.
Again so people don't misunderstand me, I don't consider mixing to be a problem regardless of my little surprise.
