You are seeing the result of water that has penetrated the barrier coat / fairing. - Use an orbital sander and sand the area down to reach the lead.
- Make sure all the areas on the edge are well bonded to the lead
- Feather the edges about 2 inches so there is no bottom paint, just the barrier coat and fairing
- Score the lead using a stiff wire brush
- Mask around the area
- mix unthickened neat epoxy and use the wire brush to work it in the scored lead
- tape release cloth over the area, squeegee smooth and let cure
- peel release cloth when cured and wash with plain water to remove any amine blush
- dry and light sand with 80 grit paper to rough up cured epoxy - hand sand so you don't burn through, then wipe clean with acetone
- apply Interprotect 2000e barrier coat - one coat and let cure
- If there are any low spots fair with epoxy thickened with microlight fairing compound and let cure
- sand with 80 grit and wipe clean with acetone
- apply 3 layers Interprotect 2000e - you can follow the timing using the thumbprint test for recoat.
- apply bottom paint within the time limit for thumbprint test, or later which requires light sanding.
