Putty to fill holes?
Hello,
We're working on our Argosy, and have multiple access points where there is a hole that something goes through (low point drain is an example) and the hole is much larger than it needs to be.
Apparently a putty of some sort was used to fill these holes at one time or another, but now it's wither gone entirely, or falling out. See photo for example.
What's the best method or product to fill these?
Thanks
Steph

When doing restorations, I use the construction spray foam insulation to fill the holes, and then trim it off after it has dried. Works great!

Awesome, I have some of that already, thanks :-) If the putty is what they used to use, the foam is a MAJOR improvement.

My guess is that they used a product called duct seal which is still used by electricians. It does stand up to the elements and pests better than spray foam.

You can also use Trempro 635 as a filler. It is what airstream used

I would think that foam would break down from vibration. I think Tempro, plumber's putty or butyl tape would be better as they stay flexible

Thanks for the responses, we're still learning and trying to figure out what is going to work best for various applications.
After doing a little Googling to see what the Trempro and butyl tape are, I think butyl tape is what's already there and falling off (who knows how old it is though). The foam seems easier, but it sounds like the general consensus is that it wont keep mice out.
Does the vulkem fill holes that are an inch or two in diameter, or is it just for seams?

I used Sikaflex and some wire mesh in one too large hole like this where wires entered on our new 23FB to preclude rodent entry. Has hrld up well for the 2 years to date. Better than the unconscionable 2" space left by AS.

You may want to consider getting some stainless steel mesh. Cut it larger than the hole, and smaller than the pipe. Bent it around the pipe to get a snug fit. Lay a bead of polyurethane glue around the hole, place the mesh on top, squish it down so the glue goes through the mesh. Put another bead on top of the mesh and squish it down (this second bead may be over kill, but I do it anyway) then put a heavy bead around the pipe and the cut that goes through the disk.
I use SS mesh because critters have very sharp teeth and may chew through the aluminum mesh, particularly if a bug or something gets into the mesh and entices the toothed critter to taste it.
On the other hand, solid aluminum flashing works also, I just like the SS mesh.
Also, it appears the hole goes through the plywood floor. If so, you may want to first seal the edge of the plywood with vanish or polyurethane sealant.

Yes, the hole goes through the floor; it seems way too big. I like the mesh combined with the silicone, DH likes the foam idea. The great thing about forums is hearing what everyone else has tried and what's worked in different situations.

We were camping out west last season, northern Utah I think, when a rodent ate through the drain hose on my Honda generator, which is mounted on my trailer. Also, this is most curious and I had never seen this prior to this campground, everyone in the BLM campground had the hood of their vehicle open. I was told it was done because the rodents in the area ate the wiring and hoses in autos. I thought they were daft until I saw the evidence. So now I park with my hood open (not at home in TN, although I have found rodent and bird nests in my engine compartment on occasion).
This is why I don't mess with foam to fill holes, and why I only use stainless steel.

Wow, those are some hardcore rodents, lol. Good to know for when we travel that way, and sounds like a good solution for whatever region of the US we would travel to.

Having the hood open permits just enough light in to discourage the critters.
Hoses and wire have been chewed even while parked at home and in the garage.
