Any high gloss finish will have a plastic/glass feel to it. and since the surface is like glass it will not be the best grip, i have a handle that Mike made me in buffarlo horn high polished natural witch has the same effect when it comes to grip. I have seen some of Rader's knives that has a glossy finish to. It's not a big deal for me i love the looks and even the feel of a smooth handle.
If you want something to look very sexy and not plan to use it as a workhorse then go for it.
I would not say that its easy to get a even finish since it depends on what your coating, a Wa handle for an example has many angles/faces witch is tricky but it can be done. It's abit time consuming and takes some time and practice before you get it right. I have seen another way to do this if u have a lathe, some ppl use a mix betwin a type of wax witch im not sure about, mixed with CA. You apply it on a soft cotton piece and then the friction from the wax will make the coating dry a even coat, while the lathe is spinning. Results is a glossy finish.
If you want to try the apply by hand method. Always use protection mask, u don't wanna breath it when you apply and sand with superglue.
Get loctite 406 or CA i guess,Rubber Gloves, Micro Mesh and Protection Mask.
Sand/polish the handle to the highest grit you can and clean the handle.
Apply a coat of 406 and make it even with your fingers. wait till its dry and repeat. 8 to 10 times is what i do.
When all layers are on work Micro Mesh from 1500 up to 12k.
When you get it right the results are just so nice..
No good before pics but here is the latest handles i did before i coated them.
After.
Here is a video of a fail attempt on my Takeda handle that a friend tried on. If you look closely you can see that the coating was not even, it can bee seen in a few angles. He tried this 3 times i think before he gave up since angles of the handle started to change from all sanding. So he went with a danish oil finish
