Stop water creeping in through a loose screw, rivet, or bolted fitting
Rivets and fastenings loosen with age and vibration, leaving tiny gaps that let water creep in – a common issue on riveted trailers like Airstreams.
Captain Tolley’s Creeping Crack Cure uses capillary action to seep into these gaps and seal them from the inside, without needing to drill out and replace the fitting.
“For years, a little leakage along the bolts and gasket. Poured some liquid and now no leaks anymore. Super good product, can anyone recommend, A+++++”
– Rene, Judge.me review
One US-based Airstream owner separately described sealing rivets on a badly-leaking horse trailer, noting it can take three or more coats and works best on a fully dry surface – a useful reminder that patience matters more than speed with a riveted panel.

*For best results, apply in dry conditions above 10°C / 50°F and keep the area dry while it cures. Cold or damp weather slows curing, and moisture can dilute the sealant before it sets, so allow extra time if conditions aren’t ideal. If you’re working in a garage or storage space, check if the air feels dry, not just that it’s out of the weather, and allow extra time to cure if it’s damp or unheated.
This works best on a true hairline gap around a screw, rivet, or bolt – finer than about 0.8mm. If you can see a fine line but can’t fit a fingernail into it, it’s a good match. A loose or missing fastening will need refitting rather than sealing.
On bare, uncoated metal it can occasionally cause light rusting over time – it works best on coated, aluminium, or stainless steel fixings. If you’re applying it around bare metal hardware, repainting or treating the area once it’s dry helps prevent this.
Yes, once fully cured – apply it in a dry spell and give it a full day before exposing it to rain, so the sealant has time to set properly.
Riveted aluminium panels, seams and window seals all rely on a thin bead of sealant to keep water out, and that seal shrinks and cracks with age, letting water track in behind the shell.
The most common usage is caused by deterioration of window seals due to movement, and exposure to the elements.
Caravan and motorhome shower trays are lighter than a home tray and flex with movement and changing temperatures, so hairline cracks in the sealant are common.
Grab handles, roof vents, awning rails, roof lights, and other fittings bolted through the bodywork all rely on a seal around each fixing point to keep water out.
