I am just about done with my pre-launch project list. Just a few items remain including re-bedding my SR Mariner knotmeter thru-hull. I pulled it out and cleaned it up because the backing block was rotted which caused it to leak when I first splashed last season. I am a little confused as to what I should bed it with. It is a plastic fitting. I have a few types of bedding compounds on hand.

<ul><li>BoatLife - LifeSeal</li>
<li>BoatLife - LifeCauk (not recommended for plastic)</li>
<li>4200 (not recommended for plastic)</li>
<li>5200</li>
</ul>

Of this list I would be more inclined to use 5200 but I really dont want to make this a "permanent" installation.

Does anyone have any recommendations?

Mark,
I think I would give SR Instruments Inc. a call and ask them. That way your sure to be on the right track. Talk to the Tech Service Department.

600 Young Street
Tonawanda, NY 14150
Phone 800.654.6360

Also this might be of interest to you.

As of 12/22/2006 SR Instruments will no longer be manufacturing marine instruments. We will still offer service and parts for the Mariner line. For further Information please contact us.

Don't know if you want to stock up on some spare parts or not.

I use 5200 for that type of application. Contrary to public opinion, 5200 can be removed with "anti-bond" that is available at boating stores. If you are fastening the thru hull mechanically then the bonding ability is actually not that crucial. Still, I'd go 5200.

Boat Life, Life Seal is good stuff. FWIW, I'd never use 5200 for an application like that.

I'd go with LifeSeal for that one, too.

The only place for 5200 on a boat is the hull to deck joint.

I'd use 5200 to bond by keel back on, but that's about it.

I'll jump on the LifeSeal bandwagon too...

That assumes you can remove the item that's bedded with the stuff and get the "anti-bond" onto the residue. After 10 years or so, that can be a problem.

OK, OK. I am coining a new term "bondaphobia" for you folks!

The boat stores are not full of tubes of 5200 because everyone is re-bonding their keels back on.

I have used 5200 for years and have put thru hulls in and taken them back off using 5200 but I do agree there are other less bondy products that will do the job you are after.

A guy at my local West store laments that the company keeps sending him cartons of 5200, and he has to keep asking customers what they're buying it for, and then recommending they buy something else! (...while his store fills up with 5200!)

Another vote for LifeSeal, but then I use that stuff for everything.
