I have two different carbon fiber veils I am trying.
One is the .2 oz stuff from ACP

and the other is the .35 oz veil from Art's Hobby.

I attached the two different veils, one to each elevator, so as to compare the two. I used a 2/1/1 mix of PC, 99% alchohol, and zinc stearate. The best reults were by painting the surface and then applying the mat to the wet surface and rubbing the PC through with the fingers.
Long story short, it seemed to work fab-o-liscious! The carbon stuck fine, I would not however waste a lot time time trying to make teeny tiny corners stay put, better to just trim and sand later. It is not, however, as easy to apply as silkspan, but it was not completely horrendous.
The ACP .2 matt is very, very loose, and really resembles something closer to a roving matt than the Art's veil.
The Art's veil is like thick, black jap tissue. With the Art's stuff say, "woodgrain? What woodgrain? Oh, it is completely gone". It also sands easier than the silkspan (did not expect that). It forms a nice gray dust when sanded, just like CF props, and the Art's matt has enough material that you can be aggressive with 180 paper.

The ACP stuff can only be lightly sanded before you go right through it.
More updates later.
