Frequently asked questions
Can surface rust just be painted over?
No. Painting over active rust traps moisture and the corrosion keeps spreading. We remove it to clean metal, treat it, then seal and coat.
How often should a fleet re-apply undercoating?
For units running year round in wet or salted conditions, an inspection and touch up every one to two years keeps corrosion from taking hold.
