Group: Forum Members Posts: 16, Visits: 122	Hello everybody, I contact you for a few problems about a carbon kevlar tray I ve made URL=http://imageshack.us/photo/my-images/707/40791410150587709709216.jpg/][/URL] My first problem is for me a real nightmare: tiny bubbles: I eliminated a lot them by using resin infusion (but not all of them) and using bristle roller but to have a perfect finish, I don't see any other way than to varnish (if there is an other possibility please let me know) So I would like to know how to make this perfectly, what products do you use (I didn't see them on your shop) and the application method to have a perfect gloss finish . For my second question, I've done this tray with 2 layers of carbon kevlar and with 2 of red traced carbon ^^ in the middle but it's too flexible specially on the flat part. I would like to know if it's possible for a next one to make it more stiff by putting a kevlar cross in the middle of the reinforcement layers Throughout the flat part and if it will be (for just one kevlar layer) visible on the exterior of the tray? Or if is it possible to make the tray for stiff by an other way (curing?) cheaper than to put 2 or 3 more carbon reinforcement layers. By advance, thank you for all your answers Edited 13 Years Ago by ARSOUILLERB26
