 In vehicles without coated weatherstripping, the weatherstripping is much more likely to cause the above-mentioned issues along with others such as rust following premature failure of the paint.That some cars have non-coated weatherstripping is surprising, given that the cost of the coating is less than US$1 to US$3 per vehicle, whereas the rubber and steel is tens of dollars; an entire car set of weatherstripping may be worth US$100 to US$300 in the total cost of the vehicle, which includes all labor and costs of the manufacturing equipment.Weatherstripping around openings – especially doors and windows – is used in buildings to keep out weather, increase interior comfort, lower utility bills, and reduce noise.
