Chris. I personally have not used the new
Hydro Tech pads or the Megs 205 but i will say this.
If cost is a issue i might suggest factoring in on average how much
Menzerna you use on a detail . . . . . it will vary but just average. Then take what you paid for the product and divide that by the ounces.
From there you should know that it takes say:
2oz on sm vehicles
3oz on med vehicles
etc . . . . and it will allow you to charge accordingly. I myself love
Menzerna stuff. It has never let me down. You can usually find deals if you shop around a little bit. 105 works excellent and i'm sure 205 works great too from what i have heard.
It's all going to be what you like to use or what you feel comfortable using in the end.
There is no wrong or right choice there is what i would say.
