I just turned my first Dimondcast pen blank. ... so you know... On all wood pens I use a CA finish, Micro Mesh down to 12,000 grit. And then put on a coat of Ren Wax.

On acrylics... I do nothing but the Micro Mesh. and al little Ren Wax

I just wet sanded with Micro Mesh the Diamond Cast.... then it occurred to me that I have never done an Alumilite material before. What do you suggest with the Diamond Cast? Do I use CA or not?

If i find the material to be somewhat "powdery", I will apply several coats of thin and medium CA. For years, I never applied CA to non-wooos/plastics and never had a problem. I just thought it would add some strength and protection. It may not do either.

I always operated on the theory that the reason for using a CA finish is to make wood feel and appear like plastic. I've never used any type of acrylic where I could obtain a better shine by adding a CA finish. I know there are turners that will not use CA on wood because they don't like that look. Different strokes for different folks. Anyway, I always sand to 600 grit, then use micromesh. Lastly I will apply some sort of polish. Hut ultra gloss is a good one but there are many others.

Thanks for checking with Tim McKenzie - I have made a DiamondCast pen and didn't think to apply CA. But it doesn't surprise me: several years ago I bought some Alumilite blanks with embedded glitter from Jonathan Brooks, and he recommended finishing with CA to get that final "pop".

I don't know if it's a function of the Alumilite or the glittery stuff embedded - perhaps the CA fills and seals any tiny air gaps between the particles and the resin, in the same way that CA (or oil) fills the pores in wood and makes the figure pop.
