RV at oceanfront and corrosion

[Jim.B1]

We have our RV undercoated annually by a company "Pro Fleet Care".
The local franchisee comes to our house and sprays the entire underbelly and inside the basement doors with a water soluble coating.
The process usually takes about 2 hours, no drip and it creeps into all crevices.
This provides great protection throughout the year.
We also spend the month of February, parked right on the Gulf coast in the Keys and I use "Salt Away" to wash down the entire coach every 4-5 days.
The product works great, inexpensive and simply attaches to your garden hose.
Rust never sleeps!

After staying 2 weeks near the beaches, weeks later when we started up our 3 A/Cs the blower motor bearings were very noisy. Each motor is $120. Plus 2 hours work to replace each.
No more salt air for us.
