Thank you!! exactly what I was looking for...and that additive link was also very helpful. I will post a couple picture examples soon for more specific guidance. We foil in areas that are rocky and sometimes touches just happen. There is a guy not far from me that does repairs well and quite reasonably priced but I prefer to be self sufficient.faklord wrote: ↑Wed May 03, 2017 9:03 amYou may get more specific advice if you post some photos of the damage you want to repair.
Meanwhile a couple of pointers:
If you not worried about cosmetics and it really is not structural, a car body filler should do the job or the standard epoxy adhesive you get in tubes. Overfill and sand back. You could even stain it afterwards with a black permanent marker pen!
Failing that fill with a mix of epoxy and ground carbon eg see products here: http://www.easycomposites.co.uk/#!/resi ... -additives
Fumed silica is great to make a thixotropic past to stop the filler running away.
On something like a wing tip or trailing edge, Clamping the part to a flat surface covered in a polythene may help to give a flat surface to build the repair on.
On something like a leading edge, pulling polythene round the edge on top of filler (and taping in place) can help form the shape and reduce sanding.
In any case whatever your filler is going to stick to needs to be clean and have a good rough surface to bond to, so I would clean with acetone/alcohol and sand with a course grit.
Hope this helps?
The rest of your post , was spot on ; but car-body filler on an epoxy board
