which sealant for screw holes in outside wall?

[Goofy]

Hi,
in the next few days I can pickup my travel trailer from the dealership.
For safety reasons I would like to install a backup camera on the rear end of the trailer.
Because I must screw the camera on and drill a hole for the cable in the wall I have to now which sealant could I use for the holes?

I think silicon isn't the right stuff to use it on unsealed fiberglass?

I would suggest one of the following:

1) Proflex/Geocel 28100; or.....
2) Dicor (the non-leveling type); or
3) Silicone would be ok too but I'd recommend 1 or 2.

I see silicone used in units in all price ranges.

A friend of mine swears by Lexel. It's sold at Lowes.

Thanks fur your advices, yesterday I drove to a marine near by us and they told me never use regular silicon on open fiberglass and recommended Marine 4200 and PL Marine for this job.
I bought PL Marine at Home Depot yesterday.

thanks again
Thomas

I use the 4200 on my boat so I would definitely use it on our 5er.

Howdy All;

Late to the dance perhaps but my choice would be Butyl tape to
cover the entire area under the assembly to be mounted. Just
screw it on and trim the excess that creeps out.
