Being that this product is a Rubberized based product, will this product actually encapsulate moisture and salts and accelerate corrosion? In the USA, rubberized undercoating has a very bad reputation for promoting corrosion. How is yours different than your competition?
This really is a waste of time and money… Workshop environment, you’d have a 24mm socket on a windy gun, undo the brake chamber and lift the caliper out the way. Now what truly would be a useful tool would be a caliper holding tool for underslung calipers such as those on trailers. Possibly just a bog standard adapter for a trolley jack… Wise words here from an experienced HGV technician, not someone who has read about the job or watched someone else struggle. You’re welcome
