Lars, This is a subject which comes up often here, as the archives will show. It doesnt rise to the level of religious dispute, however you will get differing opinions. I will tell you that I did use a sealer coat. It made the most sense to me. However my methods left a lot to be desired and I ended up regretting them (my methods, not the sealer coat). Rather than go throught the whole thing here, if you email me privately I will repeat my oft told story.
