Very good point! Unfortunately due to a lack of understanding and an in depth education on Sealers and what they do and don't do, most traders buy on price or what their mate says and never even consider:
Performance
Longevity
Coverage
Type of application
Suitability
Aesthetic appearance
They then in turn are not in a position to educate the client so end up not bothering to do it or seal it with the totally wrong thing. Remember that lead you gave me for that Landscape Gardener???
