Body Filler / Plugging Holes

Is anyone aware of a product that can be used to seal body holes? Maybe a seam sealer? I have so many extra holes in my firewall (ranging from 1/8" to 1") that I'd like to fill them. Looking for something like a silicone or other "in a tube, squeeze to apply" that I can use to fill them in. I know the preferred method would be to weld them, but I would need to pull my engine to get to many of them. (which I will most likely do in a few years) Looking for something to use in the meantime.

Thanks

 

You'd be better off with something like this: 125pc Rubber Grommet & Plug Assortment - Includes Solid Plugs - Automotive, Airplane, Marine Applications - Hardware Plugs - Amazon.com not a fan of using silicone on vehicles. Silicone can leave a residue that will come back to haunt you if you ever try to repaint.

 

I agree with the above posting. Lowe's or Home Depot also carry a selection plastic and steel plugs for various sized holes, from tiny like maybe 3/16 to over an inch. Paint them to match the body color so they are a bit less noticeable. Maybe even a light film of clear silicone to help seal them up.

 

3m makes a seam sealer that is paintable and durable in a caulk tube pricy but works well. I believe it is called fast n firm.

 

I will look into it. That's pretty much what I was looking for. Is this what you were talking about?? http://www.summitracing.com/parts/tes-08505?seid=srese1&gclid=CLGpiKukh80CFUdrfgodUnoP7Q

This is more semi-permanent. It will most likely be in the 5-10 year out range before I yank the engine, pull the tub off the frame and tackle some of the projects I have planned.


Thanks for the ideas guys!

 

Yup that's the stuff larger holes may need a duct tape backer so it won't ooooze through

 

You got the idea. Welding is the best method and stay away from the silicone products. I always had very good luck with Lexell. Just as flexible as silicone and paintable. OK, it costs a bit more as well.

 

ace hardware stores usually have a good selection of plastic and rubber hole plugs, that would be my choice. seam sealer or bondo would need a backer to keep it from oozing through the hole.

 

Are these factory holes or something else? I prefer to use removable rubber plugs and grommets where they were intended. And yes, there are a lot of holes in the tub.

 

probably a mixture of both. But I do know I put a droplight under the hood and turn off the lights in the garage, it looks like the Milky Way under my dash.

 

When I completely disassembled the donor car I bought for my jeep's engine, I couldn't believe how many rubber plugs, grommets, bumpers, etc... I ended up with. They filled two small buckets. Awesome resource to have sitting under a bench.

Maybe next time you go to a yard, start filling your pockets.

 

POR-15 and their fabric will fill a hole quite well as will their Epoxy putty (its so strong you can thread it)

 

now who would do that
