Touchless is possible
I’ve had a foam lance for a few years now and been fairly sceptical about the whole thing. Sure, it looks cool, but the performance was disappointing using the typical high st products and I really balked at paying more than a fiver for, let’s be honest, it’s just a bit of soap right?
I have a new car. It’s black. I had a black car before and in the end it looked like a spider had taken drugs and a very small knife on it, which let me to thinking that if you can get as much off as possible before any sponge or mitt goes near it, you must be a good idea.
The bottom line is that you do get what you pay for. BH recommend specific dilution rates which you can probably spend some time calculating and your flow rate, but I experimented and found the best results were half mix half water in a 1l bottle and then fiddle with the mix dial gave some amazing results. Frankly, it’s just not comparable with run of the mill stuff. I found that one coat, and leaving it (or ‘dwell time’) of about 5 mins and a single rinse got rid of almost all the film. Regularly used, you could almost consider not doing a proper wash.
Worth every penny.
