White van,..
I'm toying with the word "Thermoshine" (I hope Ionics don't decide they own that one too!) With the top of the "T" extended to the "o" at an angle,.. in the shape of a pole & brush.
The "o" could be a stylised water drop maybe??
The "Thermo" should be flame coloured, and the "shine" water coloured or bubble textured maybe??
I'll have to spend some time photoshop'ing some idea's!
I've no idea at all about an eco friendly company logo yet tho,..
