Of course, you can use any colour wax on any colour car.
You can use a dark wax on a light car so you can see where it has gone.
And you can use a wax without any colour in whatsoever, for absolute purity, which is why we made Supernatural. (Although you could always use Diamond White or Light Fantastic).
The 'general' waxes, Rainforest Rub and Hard Candy were mid-tone and cheaper than the rest. We were happy for these to sell the best and for only the adventurous to buy 'colour charged' waxes.
At no point was there any marketing or 'hype' beyond, for example, putting the Dodo wax made 'for dark coloured cars' on Purple Haze and Blue Velvet, on labels and on the website. It had after all, been made by us, specifically for dark coloured cars... but maybe we needed a big asterisk saying 'but you can use it on any colour and it won't matter that much'. :thumb:
Fast forward a few years and we are bigger and better known, and there's a detailing 'expert' on every forum. Newbies worry about coloured waxes unduly and the village elders like to pronounce that colour makes little or no difference. Well, it makes very little difference (assuming you don't want to apply a dark wax on a light car for ease of application) because waxes all tend to do a similar job and they all buff down to a sub-micron level. If you cover your whole car in a layer of coloured wax, you'd have to have bionic eyes to see the difference compared to a colour-free wax. To the naked eye and casual onlooker it makes 'no difference' in practice, no matter what is actually physically going on with the paint. There is a technical difference, but not a practical one...
A while back, I posted a colour charging demonstration up on our forum. We knew coloured waxes made little real world difference, but were the cynics right when they said it made 'absolutely no difference at all'? We found them to be wrong. The darkening effect of purple haze, multi layered, on a red panel showed a dark area where the wax had been.
DODO JUICE FORUMS • View topic - Colour charging - a demonstration... The result was seen again when I applied Purple Haze Pro in two layers to the side of our white van. It was dusk and I was at AndyC's. He saw the effect for himself... we were doing a 50/50 test and you could see a slight darkening where the wax had been after buffing.
We didn't care much about the tests because the wax range was for variety and fun, and they all worked well. People had their favourites, but it isn't a big thing for us - or wasn't until we came under fire for 'cynical' marketing practices and 'hype', all based on an assumption that because people were wanting dark waxes for dark cars we must have misled them by merely making them available. We hadn't deliberately misled people, but people did sell the idea to themselves. And we still spend our time on PMs, emails and at shows playing down the colourings.
Straight from the Dodo.
They make great waxes and good products. I looked at the photos and I don't know anyone who is going to put more then 2 coats of wax on a car. In the photos where they had the one and two coats you cannot even see the difference until the contrast was bounced up in imaging software.
Like I said if it looks good on black it will look good on white.
