i have the autobrite foam lance and its a really good product IMO... ratio of about 10:1 with the mixture, but i bought the 5L tub for $80 so should last me a fair while hahaha...... a nice little tip for mixing is to fill the bottle with water first (leaving room for the foaming agent) then just top it up with the mix, put the lid back on and give it a little shake to mix. If you put the foaming agent in first THEN water, it all foams up and bubbles before you've even got the lid on and its a pain in the arse hahaha.
I dry the car with an air dryer, you look like a tool doing it, but with the opticoat its a piece of piss and takes about 5 mins.
haha no need to "avoid" washing the car. I use the meguires woollen mitt to wash the car and it works great. As long as you rinse with the pressure washer first then you're not going to scratch or swirl the surface with opticoat applied. Ive hand washed mine multiple times and i still haven't got a single mark/scratch/swirl on the whole car.
This is the roof of my car after a wash. (the bit with the pipe is actually a reflection of the roof above)
And the bonnet
So far, I've only used the foam lance at one of those coin car washes and today I used the foam lance that came with the Bosch pressure washer with Meguiars Wash NXT Generation (the Bosch was an Xmas pressie). The Meguiars did foam 'ok', but I needed to use a 1:1 ratio of it with water in the lance's bottle to get any useful foam.
I'm definitely going to splash on the Autobrite foam lance though (even though the Bosch one did a better job than the car washer's one).
Also, I'm the lazy type that drives up and down the freeway to dry after 'sheeting'. Seems to work fine for me except for some residual water spots on the rear and side windows. What products do you guys use on your glass?
I'm doing everything I can to avoid hand washing the car, as I don't have any of the gear for it and I REALLY don't want to scratch or put swirls on it.... although I know that day will come where a hand wash is required.
