I've wondered about silicone myself—seems like a quick fix, but does it really hold up under constant vibration and weather exposure? Had a buddy who sealed up some trim pieces on his old Mustang with silicone, and after a couple years of road trips and daily driving, it started peeling away at the edges. Not a disaster, but definitely annoying to redo every so often.
Honestly, drilling might feel drastic, but at least you know it's secure. Silicone seems more temporary to me... maybe good for short-term or cosmetic stuff, but structural mounts? I'd be skeptical. Has anyone tried other sealants or adhesives that held up better over time?
"Silicone seems more temporary to me... maybe good for short-term or cosmetic stuff, but structural mounts? I'd be skeptical."
Yeah, silicone's fine for quick fixes or sealing minor leaks, but structural stuff? Nah. I've had better luck with automotive-grade polyurethane adhesive—messy as heck, but holds up way longer under vibration and weather.
Honestly, polyurethane's solid stuff, but man, ever try removing it later? Nightmare fuel. I've actually had decent luck with marine-grade adhesives—flexible enough for vibrations and less of a headache if you change your mind down the road.
Marine-grade adhesives are decent, but I'd still be cautious about relying on them for critical components. A few things to consider:
- Adhesives can degrade over time, especially with heat and vibration on long trips.
- Polyurethane might be tough to remove, but that's partly because it's designed to hold up under stress.
- Maybe look into automotive-specific flexible adhesives? They're engineered precisely for vibration and temperature extremes.
Just my two cents—better safe than sorry when you're miles from home...
"Maybe look into automotive-specific flexible adhesives? They're engineered precisely for vibration and temperature extremes."
Good point about automotive-specific adhesives, but how much pricier are they compared to marine-grade stuff? I've been using marine polyurethane on some interior trim pieces in my old VW bus, and honestly, it's held up pretty well so far. But now you've got me thinking... could it fail suddenly on a longer trip due to vibration or heat? Has anyone had that happen firsthand? I'd hate to find out the hard way halfway through a road trip...
