We do the whole range of Dodo including all of the colour dependant waxes - what colour shade did you have in mind?
With regards to the snow foam - if you are interested in learning more about what you need, I can get Jim to give you a call to talk it all through as he'll probably be a lot more help than me
If it's something you want to do straight away Jim can help with advice and which products and pressure washers to use etc., or maybe it's something he could go through with you and show you all of the equipment when we meet up?
Let me know if you want him to call and I'll put it on his to do list for tomorrow
