What's the big deal on not using silicone?

I've seen several posts over the last year with some going into shock at the suggestion of using silicone as a sealer on an RV. I'll be attaching some stuff to the exterior aluminum walls (starting with some door magnets) and won't risk leaks through the screw holes. I have a lot of carpentry experience and use silicone all the time on homes.
I suspect it may be rubber roof related. Or fiberglass?

IMO I think there are two basic reasons to avoid RTV on an RV. 1. rubber roof products incompatible. 2. nothing else will stick to it when cured.

My RV(metal sided) has RTV all over the outside of it... I sticks well to metal and whatever... not plastic vents and the like.

Well.....for starters, if/when IT needs repair, nothing will stick to it, not even fresh silicone.....(so I've been told)

So it can't be scraped off? BTW, just mounted a kick ass outdoor speaker in place of original horrible speaker using screws and 3M marine adhesive. That thing ain't going NOWHERE! Or leaking.

Yes it can, but it's a PITA.
Next time try Lexel. It will stick to itself even after it's cured.

I wouldn't use it on a rubber roof, there use Dicor, but on the rest you can use it, the reason people don't even through I do is because you can't make anything stick to it after you apply it, you would have to remove the old first, that's the only reason, the factory gave me 2 clear tubes of it they used it on mine.

X2.


I replaced my outdoor speakers and installed/sealed them in with Lexel.


First time using it on an RV, but where I've used it before, it is superior. Good stuff!

For me, the biggest reason not to use silicone on my RV is it will make hardware rust.

Check out this guys YouTube channel. He will give multiple examples as to why silicone isnít a good idea on a vehicle that shakes violently. Itís called RVroof repair.com. I am not trying to advertise for him butís was mesmerized and horrified watching the slew of repairs that he made. Itís highly educational.
