OK.
The first reason why we need to glue the edges of C/F parts is to minimise the breakage at the edges of the C/F.
Next is step by step on how i personally do it.
1. Take a rough sand paper (150 or 200) and sand the edges of the C/F. The best thing to do is have something small and flat (i.e. Zippo lighter
) and wrap a small piece of sand paper around it.
2. Next step is use a finer sand paper (800 and above) and do it all over again.
3. Wash it clean with some soap water.
4. CA those C/F edges,
It works for me.
Hope it does the same for you.
