No idea carl I guess tt11 didn’t lacquer it anyways thanks for the help and info I will do these things by my self from now on.
Maybe I will hazard a guess. One time I let someone seal a blade for me. He used a water based sealant that was from Xiom, so it was a sealant from an actual TT company. That sealant, I did not like how it worked at all. The glue stuck really hard to it. So the rubber was hard to remove. So, I applied the kind sealant I like to the blade instead.
The sealant I use makes it so the rubber comes off kind of easily. It also keeps the water from a water based glue from sinking into the wood because the wood has a layer that is waterproof protecting it.
I guess it depends more on how often you gonna reglue or maybe even boost your rubbers if any sealent is needed (besided of the kind of blade you are using - some you really have to seal it).
In my experience with several blade - if you glue often and boost, you have to seal that blade. otherwise that thing will splinter quite fast.
For example: my last Yinhe V-10 pro lost some of his wood^^ after the second gluing already without any sealing done before.
Limba as a top ply benefits from being sealed because it is easy to damage Limba. A wood like Koto or White Ash or most of the other harder top plies don't really seem to need sealing as a result of splintering. Because the wood is harder, it is rare for those kinds of woods to splinter the way a delicate Limba top ply can splinter.
So, I would definitely seal most Limba blades. The exception may be that a Butterfly blade with a Limba top ply usually won't need sealant for splintering because of the way Butterfly makes their blades. But, I still would seal a Butterfly blade even though I don't feel it needs it.
But, it is true that, when using a blade made by one of those Chinese companies like Yinhe, the price/build quality is something you have to be aware of. Those blades are excellent for how inexpensive they are. But they are not the best crafted blades. So, yeah, it would be worth sealing a Yinhe blade.
In any case, a good polyurethane sealant from a HARDWARE store, not from a TT company should allow you to use one thin layer of sealant.
Remember, TT companies have a vested interest in you buying more products. So, maybe a sealant sold by a TT company is not exactly what you would want.
