Where dust actually gets in, why a tailgate dust kit matters more than the canopy seal, and how to test yours.
Dust is the thing that decides whether you enjoy a canopy or fight it. It does not usually come in where people expect.
The tailgate is the problem, not the canopy
On most utes the biggest gap is the factory tailgate, not the canopy seal. The tailgate was never sealed by the manufacturer because the tub was never meant to be a sealed box. Fit the best canopy in the world to an unsealed tailgate and you will still find dust inside. A tailgate dust kit does more for a dusty trip than anything else you can buy.
Where else it gets in
Check the corners of the door seals, where a seal has to turn a radius and is most likely to lift. Check any hole you or a fitter has made for wiring, because a cable through a grommet that is not sealed is a direct path. Check the drain points, which are meant to let water out and will let dust in if they are not shielded.
Positive pressure works
An air vent set to pressurise the canopy keeps dust out by pushing air outward through the gaps rather than letting it draw inward. It is a small part and it is more effective than adding more seal.
How to test yours
Drive a dusty road, then park and open the doors and look along the seals with a torch before you unpack. Dust leaves a track where it came in. A cheap alternative is to wipe the inside of the seal with your finger after a trip. If your finger is clean, the seal is doing its job.
Seals bed in over the first few weeks and they are adjustable. If dust is getting in after a trip or two, bring it back to the centre that fitted it. That adjustment is part of the annual service.
