Mat vs Cloth and Carbon Fiber

Hi, I hope everyone's projects are going great. I am getting ready to do some glass work and am hoping for a little help/advice on the best products to use, in particular there are 3 things that I have had a hard time finding an answer to: 1) I noticed that the " chopped mat " seems to be the prefered material of a vast majority of this forum's users.Can anyone tell me if there is an advantage over 4oz E glass, as they are similar in price? 2) Does Vinyl Ester Resin need a sanding agent to fully cure? 3) What is the best product to use on carbon fiber, the carbon fiber will be used over glass for cosmetic purposes? Thank's, any help is greatly appreciated. Stormshadow

drunkenbreaker Thanks for the reply. I apologise for the late response, I have been working 16/7 and this is the first chance I have had to log on. I was thinking along the lines of making the part out of fiberglass, finished to the point where it would be ready to prime, then applying the CF to a epoxy tack coat. I have a vac bag system I can use to remove the air pockets and apply even pressure to the piece. I was thinking that I could then apply the final finish, maybe clear coat?, to the CF cloth using my HVLP sprayer. I have a Capspray CS-9100. I will not, of course, simply go out and try to make the piece/panels without some extensive trial and error to see   if any method works. The CF cloth is soooo damn expensive I hate to waste even an couple of inches. I was thinking I would start my testing with 3 different pices, each approximately 2" X 2". The first is a A/C knob, high contour. The second will be a tweeter cover, medium contour. The third will be flat, low contour & control group. I will take, and post, pic's as time allows. I plan on starting next weekend, but it may be July before I can get to it. Thank's again for the info. If you have any more advice, or see any shortcomings in my methods, please let me know.
