The crack seems to be on the surface, but I am not certain if it has gone through the part (I do not want to pressure it to make it worse). There are in fact 2 cracks - one larger exposed one and another hair line crack below (see image) Unfortunately this part is NOT accessible from behind as it is one closed piece. I am thinking of sanding the crack with a small file by hand rather than using a Dremel not to risk cutting through it. Then filling the crack with a clear lower viscosity epoxy resin (using a syringe) and then polishing it. Any other alternatives to this ? I am concerned with cracks growing so I have considered drilling small holes on their ends to prevent further opening. Does this method (often used in metal) also work for Carbon Fiber ? (See image) I also will need to fill the holes afterwards. Many Thanks in advance Tags c/f cracked cracks repair repairing Edited 8 Years Ago by fibernoob
