I am defentley not going to get into this again. J.

We use both brands and have never had an issue. Usually comes down to color - or where we purchase our tile. Sealers are always a good idea - as long as you are using a penetrating sealer - not a film. Sealers need to be re-applied periodically. If you use the area daily, then you may need to reseal every 6 months. Not as much usage - the sealer will last longer. But do not count on sealers to prevent stains - they will help keep it looking good longer, but you can still stain sealed grout.

Sorry, just saw this. I feel two coats of finish is sufficient when applied over sealer at the prescribed rate. This is especially true for Traffic which goes on heavier (350-400 sq. ft/gallon for Traffic, 500-600 for Mega). More coats of finish make the floor smoother, filling in the grain, and making wear and scratches more evident. If you're in a situation where you need more longevity, you can have more coats applied and live with the consequences. In most residential situations my customers want their floor recoated when it looks bad due to wear and scratches, not when the finish wears through. The surface accumulates the same amount of wear and scratches whether it has 2 coats or 20 coats, at which point it will look a bit shabby and require a recoat.

Here are some that I have. It is very tough to get them to look true to how they look in person unfortunately :( . So I was trying to get more of a feel of how these have turned out for other people, but maybe these pictures will help? First one is them side by side and second one is me trying to get close pics of one at a time. Thank you for your help and advice!
