I've never used the megs hyper dressing, but i went to their site and seen its a water based dressing. I'd try using it diluted 1/1 for a high shine and maybe 3 or 4/1 for a low shine. You could dilute it even more and see how it looks.
It's alright to use silicone based dressings also just so you know. I actually prefer the look over water based on my dash.
While i was there i seen this on thier description of hyper dressing.
Until now, the industry average for diluting water based dressings has been one to one or ready-to-use.
Are they serious? Automagic has been making water based dressings that can be cut up to 4,5 times and still have a nice shine for a long time now.
