GOOP vs 3M 5200 - Kayak Fishing Adventures on Big Water’s Edge

dtownfan · 02-28-2010, 06:43 AM

i am working on shaping the contour of the bottom of my wet mount transducer today. i have a 4 inch version of dsafety's wet mount and would like to know what you fellas think about stick'en her down. i have a 135 ride and must create a contour very similar to that of dgax65's wet mount on the "share your innovations" thread, rounded V pattern to match the center of the hull. after reading the specs on 3M 5200 i know when the wet mount is mounted......it is not going to move, maybe never. problem is i have only read about using goop and 3M 5200.....no experience.

what do you think? GOOP vs 3M 5200

the 5200, when cured, has characteristics more like caulk - it is flexible. The goop is more rigid, like a cured epoxy. That being said, the 5200 is slick & slimy & takes longer to cure. Viscosity-wise, I think the goop is more viscous & would be easier to work with for this application. Also I don't know about 5200 conductivity of the soundwaves. Since it is less stiff it may interfere with the pinging. I don't see 5200 being really good for "build up" type applications, so if you have a bigger gap to fill you may be better with goop. But if you are going to be seeing extreme temp swings you may be better with the flexibility of teh 5200.

I know, I did not give any answer & I'm far from a pro on these. But I have worked successfully with both

I disagree. Goop is very flexible when cured. I think the Goop should be sufficient for this application, although I do think the 5200 would provide a stronger bond, as it is designed for through hull applications. There really isn't a lot of water pressure that will be going on where you are planning to use the product. With that in mind, I would prep the surface really well by scuffing it with a heavy grit sand paper and cleaning it with acetone or alcohol, and I would go with the Goop because of its great flexibilty when cured.

Ive used both and have been happy. The only drawback I had with the white 5200 I used was the mess. It was my first instalation and add the spaz factor... My beads were not up to par and it showed.

Yeah 5200 is a pain. If you go this route wear gloves. trust me.

Both products work well but if you plan on using the sonar within a week or so I would go Goop as it cures faster. 5200 takes a long time to fully cure all the way through (even the fast cure stuff takes a while).

thanks for the info! i have a tube of marine GOOP here at the house and wanna give it a shot. i will post pics when i finisher her up. i spent the day making a home for the new yaks so i have not even started the contour carving for the wet mount. this weekend me make the trip to farmville va to get my 135 ride......went for one and picked up 2! i bought my wife a Tarpon 100 and a carbon manta ray paddle. when the wife is happy, i am happy'er!
