What are opinions on getting this done professionally? Obviously doing it yourself would be far cheaper but I don't have the confidence or expertise to do it well.

I came across Glosstech who offer the full range of Gtechniq products.

Does anyone have experience or alternatives?

It all sounds good but the cost would sure add up!
