Looking for some suggestions for a product I can use to seal the backing plates for my 4-point roll bar on the bottom of my car. I am looking for something that stays pliable and keeps the water out, I was thinking butyl rubber for sealing an older car's windshield might fit the bill here. I'd prefer it not be silicone so I can swap the bar in and out of the car as needed. Ideas?
Masterseal NP1. Stays flexible forever, sticks to anything.
It does take a while to set.
It is a pain to clean up after.
Once you open the tube it's done, even if you only use one squirt.
It's all I use professionally for metal door systems. Good stuff.
Maybe sill flashing tape?
3m strip caulk.
There is a grey putty the electricians use to seal around wire and tube entries into the building. Don't know what its called, but its cheap, and it seals holes real well, and its in the electrical aisle at the big box stores. I use it when I put in irrigation back flow preventers where the copper pipes leave the building. Like silly putty for adults. depending on pipe diameter, you could use a plug for the ends of pipes. Whenever I buy a boiler or water heater, the threaded pipes sticking out always have plastic caps on them to seal them up. I have a box full of them and use them to cover openings in engines when I'm working on them so nothing falls down in.

"Monkey E36 M3" is what its called but not sure what the label reads... On the down side its flammable and gets runny when hot so don't use it where you might find high heat..
How about auto body seam sealing tape?

It's called Ductseal. It's pretty similar in consistency to the 3M strip caulk I mentioned early, but the 3M product is pretty inexpensive as well and is available at most auto parts stores. It's also useful for many other automotive applications so it's well worth having some on hand.
I'll second NP1. Don't get it on your hands or hootus.
Rubberized undercoat.
