Smart repair paint scheme advice

[neefern]

Hi everyone I'm new to this website I've noticed it always appears in my Google search results offering good advice from your members. Here's my question I've been spraying my own cars & repairing family & friends cars for a good few years now & I've always bought max Mayer solvent paint from my local motor factor ready mixed to spray through a HVLP gravity gun so one day I seen a lechler hydrofan waterbased paint scheme going cheap on ebay. Thought great no messing i can knock up small amounts of paint ready to use only thing is I haven't got a clue how mixing water based paint works. I understand how to use the software entering the colour code and that you use the scales to measure the amounts of colours to mix but I'm just basically guessing. I would be amazingly grateful if someone could give me advice on how I should be using the kit.

Cheers Neil
