CarPro Hydrofoam users...please chime in!

I use HydroFoam a lot with 2 of our cars but don’t recommend using it in a foam gun/canon. You don’t want get it on everything especially the windows. I fill my wash bucket with about 4 gallons and add 3oz of HydroFoam. Wash a panel at a time and try avoid getting on windows.

They (CarPro) should make a revision in their directions about this

If you're detailing in an indoor climate controlled wash bay, then it's perfectly fine.

Fine for the entire car, including glass?

It's a joke, car pro instructions for their products always seem to be for the ones with a perfect climate and humidity controlled wash bay. It's why so many of their products streak.

I’ve used hydrofoam outside every time and have sprayed the entire car- only had streaking once when it dried in the sun.
When foamed on, washed with a mitt and then power washed off like the directions say, it works great.

Well...it's going to be about 40 degrees down in the garage, so not a lot of warmth and NO sun. If I wait till Sunday it's going to be 32, so it could be in the mid 40's down in the garage🤣

Thanks for all the input guys!

I did the first wash of Hydrofoam on my wife's Mazda 6 this morning. It was treated with McKee's Hydro Blue Sio2 spray last weekend but was covered with a weeks salt dusting. The temp down in the garage was about 35, so I decided to get after it.

I did a 1:9 ratio in my soap dispenser and 1 oz of CarPro into my wash bucket and made 3.5 gallons of wash. I "foamed" the car down real good, everything, and it broke down the salt and muck nicely. I then did the 2BM wash and very early into the wash I noticed the suds evaporated but kept at it. While washing the hood you could see "something" in the wash and I believe it's the Sio2 properties, couldn't wait to finish and lack of suds didn't bother me one bit. Speaking of that, isn't 1 oz for 3.5 gallons enough anyways?

Once done I foamed the car again and THEN rinsed the car down. Upon rinsing I noticed the beading right away but like I said, I appllied McKee's Hydro Blue Sio2 spray just last week but I'm going with it being the Hydrofoam doing it's thing.

The results were Great! The drying was done with 2 towels, average sized ones...a thick plush one for the sopping and a Griot's PFM to finish things off! The gloss left behind was VERY impressive as well.

I plan on using this product once a month on my own car because it's a general concensious that over using this isn't a good thing due to build up...true or false in your uses?

Btw no streaking using it my way but I used my wife's car as a guinea pig and it's not coated either. Thoughts?

Glad it worked out, Roger.

I think my issue with HydroFoam was the fact that I did the whole car like I normally would foam, and some areas dried out before I was able to complete the washing/rinsing job. Usually that's been in the summer when the temps are much higher. Perhaps at 35 degrees things are different. I think once per month is a reasonable thing.

So when it would dry out couldn't you just wet it down again or hit it with some WW?

SiO2 must have partially cured by that time -- either way, couldn't get it out with a WW, RW or 2BW. The only thing that got rid of it was time + polishing. A similar thing happened when I first tried Reload - streaking. It got better only with time + polishing. That plus lackluster performance from PERL is what turned me off of CarPro products for a while.
