I have been wondering about this product. Thanks for mentioning it!
Here’s an interesting story about D115... Last month I polished my friends Dodge SRT that I 1st detailed just over 3yrs. ago. Back then his routine would be to bucket wash it at least once per week maybe sooner, and although he loves his car and likes the process of maintaining it, he mentioned how it was somewhat of a chore to always have to pull out the hose & bucket...
So I gave him the pitch on waterless washing, not really sure if he would seriously consider it because you know how most people are in general when they 1st hear about it. But he was willing and didn’t waste any time buying himself a gallon of Megs D115 and began diluting it @4:1 just like I recommended it along with a pack of Kirklands + I let him have 1 of my Water Magnets so he could have a proper drying towel.
This dude became the waterless wash king! Lol. He hasn’t done a bucket wash in the past 3yrs! He simply does his waterless wash wipedown every 3-4 days and his ride always looks super clean.
So recently I had been reminding him that we should get together and work on his car again because I was sure it would need a claying after all this time and a quik polish as well... I show up early morning on a Saturday, do a quik waterless with D114, begin claying with the Megs white claybar because I want to show him what we’re removing and it’s completely smooth... Nothing. I pretty much ended up claying most of the car waiting and expecting to run into some kind of contamination somewhere?! Well guess what, I didn’t... My mind was blown. I could not believe D115 actually protected his paint from bonded contaminants for 3+ yrs!

Wow.
Once I was done with the detail I told him to keep doing what he’s doing because I had never even heard anyone claim to have the kind of results that he was having. Lol. I’ve certainly never seen it before and I’m too lazy to have accomplished it on my own ride for that long.
I did toss him a Griots PFM to replace his old Water Magnet.. I asked him the other day how that little gray towel is doing? He laughed and said he lost the Water Magnet on purpose, he doesn’t know or care where it is all he knows is he loves that little gray towel!

lol.
