a tisket a tasket i wanna make a gasket

[Sailor Robius]

hello all,

has anyone tried to create a solid gasket out of 5200, or other material, by applying it to one part and letting it dry before mounting to the other? another though i had was laying wax paper over the part to be sealed and tracing a bead with the 5200 along the edges, letting it cure, then removing it from the paper and using it as a traditional gasket.

thoughts?
thanks in advance.

There are products made for that purpose. Permatex is one company brand of these items.

Google "gasket maker selector" for a pdf file of their product descriptions.

edit,... here's the page with the selector info. There are twelve different products for various applications.

You havn't told us what you are trying to gasket.
+1 on the Permetex. They make several "Form a Gasket" products that are specific to the application. i.e., temp, pressure, material (oil, water, etc.).
Each one is a different color so they are easy to spot. Ask for the 'blue goo" and start there.
Any decent auto parts supplier will have a pretty good selection.
Most mechanics will have a tube of "blue goo" in the top of their toolbox.
PSon't use 5200 for gasketing anything short of a hull to deck joint!

Much depends on what the gasket is supposed to seal.

Anyway - it IS difficult to spread the goo evenly, so if you want the gasket to be of even thickness then simply make it out of say rubber.

good point. the intended application is above decks so it will be used to seal hardware, the windlass, etc.

Haven't they outlawed 5200 yet?
Yeah, to get it exactly even is the trick. More effort than it's worth

Tellie, When the US outlaws 5200, bails of it will be dropped from low flying airplanes to waiting speedboats. Landing strips will be cleared in the Everglades. 3M runners will make quick trips to Bimini to bring loads back. Law enforcement will start tracking the "street price". When are you coming to visit me?

sound logic. i may trot over to the local HD and pick up a piece of rubber pond lining and try that first. i think it would be about the right thickness and it's cheap so.....

I would suggest a good auto parts store over Home Depot. I could not locate a gasket for the end cap of my heat exchanger. Purchased some gasket material at a parts store, used the end cap as a guide and in in less time than it took to get the material, Viola! a gasket. The remainder of the material is on board.... Just in case.

Butyl rubber pond liner makes great gaskets. I made one for my raw water strainer and it did the trick.

To make the bolt holes in the gasket material...

Cut out the gasket from sheet of material. To make the holes lay it over the part with the holes and position a larger diameter steel ball bearing on the center of each hole. Press firmly and then hit the ball with a hammer. You can get a perfect cutout.

LOL, 5200, it's a love hate relationship.
Be careful what you ask for, I just might stop in for a visit and ruin my Super Hero persona.

From what I read into this is you want to bed these items.?
dry fit the windless and draw an out line around the base. remove windless and mask up the area outside the line. use 4200 or calk life bed the windless and dont listen to the story's about not tightening all the way up until the calk sets, just do it up tight straight away. Smooth the excess calk and remove tape and re smooth the calk and you done.

Not sure why I assumed you were referring to gaskets for an engine project, for which Permagasket would be a good choice.

But for bedding deck hardware there are far better choices as mentioned above.

One day I'll learn not to be the first to reply.
