Wiltec rust proofing undercoat spray gun review (same as Sealey air operated wax injector kit SG18)

Подробнее о видео

This is a review of the Wiltec underseal spray gun. I purchased this spray gun on Amazon
Amazon product description: Spray Gun w/Pressure Cup 1100ml 4-6bar 1/4" Cavity Gun w/Hoses Spray Gun w/Hook and Round Nozzle
In this video I am treating the underbody on my 2021 Nissan Navara NP300 pickup to some rust protection using Bilt Hamber Dynax-UB.
This Wiltec spray gun is the same item as the Sealey SG18 wax injector kit (see ) but at nearly half the price.
This video was filmed in June 2025.
