Rebedding deck hardware today, and I discovered mucho silicon used in previous bedding attempts.

Any tips for silicon removal?

sand, scrub sand and scrub some more. IPA (isopropyl alcohol) helps with silicone.

I just finished removing silicone from the cabin top where the handrails are mounted. It's a job, but I got good results from (1) scraping off as much as possible with a plastic putty knife, (2} wiping the area with Goo Gone, (3) scraping carefully again with a metal putty knife, (4) wiping again with Goo Gone. It's probably not perfect, but it'll do. I'll use butyl tape to mount the handrails this time.

When down to a very thin residue, roll it off with your very dry fingers.

I never tried this stuff, but have heard it recommended.

If anyone tries it, I'd be interested in knowing whether it works.

It's worse than that.

A DPO put gobs of silicone on a previous C25 and I spent days getting it off. After trying a number of different tools, I found a single edge razor blade (in a handle) was the most productive. Becareful on gelcoat - you can nick it. Solvents do help (after you cut the majority of it off) but still a tedious, frustrating process.

Good luck!

I might give aMr. Clean Magic Eraser a try after scraping. I haven't tried them on silicone, but they have worked on everything else that I've tried. They even took dried Cetol off the gelcoat.

WEll, here's what I ended up with - Tried some scraping, but its slow going on non-skid, so that sucked. I have strong fingernails, and scratching at it worked somewhat. A stiff bristle brush worked pretty well. IPA had minimal effect (sort of polished the surface, but not much else). Finally, I grabbed a piece of drawer liner from my tool box (its grippy) and put it in a palm sander. The heat it generated, and the motion from the sander actually got a lot of the silicone to release.

Then it was backwards through the list again. Got most of it off, but each stanction base took a good 40 minutes.

ETA - I know no one asked or called me out on it, but here's some bonus info for following along: http://www.wisegeek.org/what-is-the-difference-between-silicon-and-silicone.htm

I thought it was a Canadian spelling . Silicon or Silicone it's still a GIANT PIA to remove . Not sure I have discovered an exclusive application for it on a boat.

Use a torch to heat it up, then scrape it off...

The only place silicone should be used is on Beckson ports, for those of you who are considering adding a portlight in the vertical face of the starboard cockpit seat. Beckson insists on silicone, and it works well (we have eight Beckson ports on our boat).

Otherwise, butyl tape for all bedding.
