Thing is is that the guys who have been doing anything for a while have means and methods that Work for them!!! I would not mess with that as that guy knows what he needs to do in his shop to get a good result..That does not mean we are not willing to look at things that may be a better way of doing things in some way..MARTINSR said:"Less room for a screw up", not only that, but if something does go wrong, it is the products that YOU picked. I don't care if the guy made every mistake in the book he will likely blame the products YOU provided. I say stick with what the guy knows best, UNLESS there is something wrong with it. And there is nothing wrong with Sikkens products (on a whole).
