Because I am occasionally a dumbass I neglected to raise my rudder before hauling the boat out the lake and now I have a flat spot on the leading edge bottom corner of the rudder. The local west marine pointed me in the direction of Marine-Tex. It seamed easy enough to use which is half the reason I am nervous, plus the "catalyst" looked to be steeming, like hot coffee when I opened it. Does anyone have any expirence with this product and if so, how well did it work for you and is there anything I should be careful of while using it. Thanks in advance Brad s/v Kivalo

Good Stuff

Ever work with Bondo on a car? About the same deal. If it makes you feel better I think we've all done that at least once.

Marine Tex is...

... one great product. I have used this stuff for many years and it has never let me down. I used it once to fill a small thru-hull, thinking it would be a temporary repair until I had the time to glass it in properly. 20 yrs later, it was still in place and as good as new. Both parts should be inert and cool when not mixed, so I don't understand why the catalyst appeared "steaming" to you. When mixed together, the product will get VERY hot, but this is normal (and indicates it's working properly). But be prepared for the fact that once it cures, it is as hard as steel, a bit hard to sand, and impossible to remove. But that's what you want, right?

thank you

Thanks for the help. So far it seems to work great but I didnt smooth it out while "wet" so it looks funny when the rudder is up, but hey its not a race boat, so it doesnt really matter thanks Brad

Marine Tex can not be beat

For me, Marine Tex is one of those miracle products right up there with WD40. Sanding is an issue. I appreciate the comment from Tom in Boston. I will try that next time.

The one and only problem...

...with Marine-Tex is that it cannot be used under water UNTIL it is cured. The hardener like most 2 part epoxy's is water soluble. Once the repair is setup and cured it is fine for underwater applications.

Use water

...because Marine Tex is water soluble, as the product initally begins to harden I use my hands (covered with latex gloves) to mold the mixture. Wet your hands and mold, smooth out the product. After it has hardened sand with 400 /600 grit wet sandpaper. I have used this on numerous boat dings including a hole in the side my Sunfish. By the second day it was difficult to find the repair. I keep it around all the time. Last year I repaired a hole in a fiberglass swimming pool. Great stuff.

WD40

Got to agree that Marine Tex is a great product. However, WD40 is probably one of the most misused products out there. Many people use it as their primary lubricant, but it isn't a lube. No where on the container does it even claim to be. WD stands for Water Displacer. As a lube, it's not very good. Sorry for the rant, but I hope it helps someone avoid future problems caused by using the wrong product. Ron
