I just wanted one for when I'm looking at cars to buy to see if they've been sprayed and how much. Only need a cheap one but needs to work.

PaintDetective, google it, about as "cheap" as it gets.

I'll help you :think:

You planning on buying and selling some motor's Martyn...........

Took my PTG and Brinkmann along to look at a lot of motor's of late and some people always get a bit funny about it but it's a fair investment if you do want to by one, the cheapest will be the PD8 for sure but there are some others available, worth bearing in mind that unless your spending some big money these sort of PTG's won't read plastic........ :think:
