Does anybody have any tips on how to put two carbon fibre parts together while making It look 'natural'? Or if anyone has done a carbon fibre AirPods case before and could point out some tips I would be extremely grateful. Thanks in advance! Raf

Though, now that I reached this stage, what is the next best recommended move to ready the mold? Would I need to wet sand it, polish it, then add mold sealer and so on? (The mold was produced using Black Tooling Gelcoat) Any suggestions would be kindly appreciated. Raf

How was the release? did it come off easily? Sometimes on thin sheets, if the release is a bit tougher than usual, as you peel the sheet off you can get the beginning of stress fractures or cracks where it flexes a little too much and that can look like that before it becomes proper visual cracks if flexed even further.

R Group: Forum Members Posts: 19, Visits: 84	Thank you, much appreciated! As seen on the photo below I have been getting this white sort of finish. the reflection of the light is pretty clear. However, that the scratches and the "White finish" is ruining the part. What could this be? The resin, the finish of the plug? Once again, any suggestions on how to avoid this and get a great finish would be appreciated it.

You don't need to physically weigh it out if that's a bit awkward, just calculate it from the nominal weight of the cloth and surface area used. eg a 200gsm cloth, 2sqm and 4 layers would need 1.6kg of resin plus a little extra for waste etc. If you do infusion, you can take into account resin uptake of the peel ply, mesh and bit for spiral and hoses. You can also reduce the resin ratio to 60:40 fibre:resin as it is more efficient. Warren Penalver Easy Composites / Carbon Mods - Technical Support Assistant Edited 4 Years Ago by Warren (Staff)
