I've read the posts in this particular thread and think they are well thought out, but for Craig to come on here and continually defend the course means he s always on the back foot.
There may well be a degree of sales involved, it is an Ionics driven course after all.
But the techniques shown are based in many years of experience and practice.
They may well push their own, I really don't know, but the methods shown will hold good for all systems.
Can they teach spot free cleaning?
Well that just has to depend on you, how on earth can they guarantee that?
They can show you best practice, the best way to avoid things like repetitive strain injury.
I could teach you how to prepare, prime, undercoat and gloss a flush door, but the moment you go out and try to do it you will screw it up, guaranteed.
where WFP is concerned, there are so many variables, types of glass, types of frames, the condition of the frames, the weather conditions, how damaged is the glass.
you can be shown the techniques, and if you are a greenhorn you will learn plenty, if you are experienced you will probably learn things that will surprise you, but I do not see how they can guarantee to teach you how to do spot free WFP'ing, it is a skill you have to develop.
They can show you the pitfalls, the things to avoid, they can point you in the right direction, they can give you the information you need to go forward. But it takes time to develop the necessary skills you will need to do a top job, a day long course will not give you these skills.
Have a good day now!
