Slightly crossed wires here, I was referring to using some form of 'wipe on' varnish rather than brushing.
Yes. Which is why I said, that if he wanted to put a thin coat, he should follow your directions. But he was also asking about putting a thicker coat with several layers. And I also answered that information. So, my wires were not crossed. But you may not have realized that I answered all of the questions he asked rather than just telling him you have to thin the sealant without giving any context. This was my basic answer.
1) If he wants to use that stuff for wiping on to get a thin layer, then your answer that he should dilute it is the answer.
2) If he wants a thicker layer than he may as well not dilute it.
Hopefully the numbers help.
I did not say how to apply it. But I figured any reasonable person would figure out one of several ways of applying that particular sealant that James Livesey linked to. If it is too thick to apply by wiping on, I personally would use a brush.
Are your wires still crossed. Here, read my original post and see if it makes more sense now:
For the answer to the question of whether to dilute that sealant, if you are trying to make a thin coat, see GinjaNinja's post.
If you are trying to make a thick sealing layer to make the blade harder, do not dilute it.
Blades like the NCT blades from Stiga use a thick layer of a kind of sealant to make the blade harder. The sealant they use is probably a little harder than the ones you have access to. But it is the same principle you are asking about.
I personally would just get a different blade if I wanted something harder and faster. But it can be done.
If you try and don't like how it feels, you can remove the sealant or simply get a blade you will like more.
