Stuff on frame rails

[NC SVT F150]

I got my '01 lightning on 8/14/01. I attempeted to retain all factory stickers and covers. I looked under at the frame and noticed the stickers on the frame. One near right front that has SVT . another one under pass door with vin one near front of bed with date code. When i remove date codes i had no problem but the SVT took the coating off the rail. I then touched it and its like a grease or not dry yewt paint or undercoating its real thick. I had noticed some spots where the fram was mared probley with a chain fron tie down on transporter.

Question is does these stuff suppose to dry or what??

It might dry after a while but I've had my L for over a year and I still get that stuff on me everytime I get under there to work on something. I guess over time it gets covered with road dirt and isn't so sticky.
