Port removal

The previous owner of my Helms 25 replaced the 4 port glass windows and sealed everything in with a white sealant. Unfortunitally they still leak. These are the typical aluminum track port mounts that were used in the 70's.
My problem is that I can't break the sealant loose between the aluminum track and the fiberglass hull. He did this in the mid 90's, so I'm not sure if he used a polysulfide or a polyurethane like 5200. I hope its not 5200. Has anyone had success in breaking the bond on 5200 or polysulfide? Have you tried Anti-Bond 2015? Does it work? Will it dammage gelcoat? Any ideas would be appreciated.
BTW, the aluminum trim is in great condition so I don't want to bend it up.

Thanks,

Wayne

Wayne,

There are almost no chemicals to remove old silicone or sikaflex products, and the existing ones weaken the gelcoat.

What I do, when I need to remove it, is a sharp exacto blade and a piano wire, with two handles, that you skeeze on one end and pull/push all the way around. Like a saw. Hope I explained ok...

Once removed the port, you scrape the rest with the knife and accetone.

It's hard to remove, and has to be "mechanical" removal, not "chemical".

You're welcome...I found that after you remove the part, to remove the remaining silicone, rubbing with my finger, until released works fine, also.

You need to use a solvent to remove the silicone residue, or the new sealant will probably not stick properly.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

I tried the Marine Formula from DeBond on the white caulking holding in the ports. It said it would not harm gelcoat, but I tried a small area and it didn't seem to soffen or change the gelcoat at all. I ran a razor knife around the sealant joint as directed and sprayed just a little of the product all around the exterior edge. Waited about 5 minutes and applied a little more. Then in about 20 minutes, and with a little pressure from the inside, the port started to pull away from the gelcoat. It left the white caulk (which I assume was a polyurethane like 5200 or a polysulfide) looking like a flat gasket. This sounds like a commercial, but the stuff did what it said it was going to do. I also tried it on some silicone on another piece I had removed and it worked well removing it from the surface.
