I think- if you used to using Silkspan you shouldnt have any problems with Carbon Veil.. It applys a little differently.. I think the key is try to handle it as little as possible.
A technique I use when laying it down is to cut a Big piece, and lay it down in sections, and trim it to suit.
What I mean is - lets say you are trying to do a fuselage, id cut a peice 4" wide X 30 " long, - start laying it down by dabbing dope to the carbon , not worried at this stage about overlap or over hang, slowly move down the fuze, and if I need to trim, get a sharp exacto blade and slice - very gently along where you want it cut - wing, flap, fillet, whereever.. it cuts SO easily... then continue to lay it down, try to handle it as little as possible.
Corners. tight corners, I like to let it tack off dry after 10 mins, before I try to get it to go around a compound curve like the inside of a cowl, do the outside 1st up to the edge. let it go off, then wrap it around with more dope, it will hold easier.
The learnign curve for me was 1 plane. Make some mistakes, 2nd plane was great... - Many models later, its perfect.
