Hauled the boat - What's this on my keel?
I hauled my 1986 Bene F26 on Thursday for a bottom painting job.
I noticed something on my keel (I believe steel) that I don't know what it is. See photo
This looks like a welding ridge on the keel - both sides look like this. Can anyone shed some light on this.
Also, I found three blisters. Two of them seemed to be just under the paint - they were very soft and flexible and burst with very little pressure. The third needed a hard poke with a screwdriver to burst. Once I removed most of the hull paint, I noticed that all three blisters are in previously repaired areas of the hull - see the photo.
Is this "normal" to see blisters in the previous repaired areas? or does this mean the repair was not up to snuff? Wrong epoxy used? (It's probably been 5 to 7 years since the last repair)
I plan to grind out the entire area (as marked on the photo) and redo the repair.
I also noticed that there are three other old blister repair sites (all much smaller than the one in the photo) that seems to be ok.
One more question - as I plan to coat the bottom with Pettite barrier paint before painting with Pettite Trinidad SR - what should the bottom prep look like.
I've stripped off the old ablative paint using Soy-strip and will sand with 60 grit paper to scuff up, but the question is, Must all signs of the old paint be gone - in other words virgin white gel coat, or is it ok to have some blush of the old black still showing?
