Under Carriage Protective Coating

Is there anyway to find out if your under carriage has already been sprayed with the protective coating? I have a 2013 Tacoma Texas Edition and I bought it used with 5,000 miles on it. I don't want to go and spend the $300 to get it sprayed if it was already sprayed by the previous owner or the dealership already.... Let me know fellas! Thanks

UH...Look at the frame...????

 

I know that, but I am saying is there a specific color that it would be if it was coated? You know what I mean?

 

Only 300 lol. I don't think that you really need to worry about it since that you live in Texas. Unless you get snow 9 months out of the year, I wouldn't worry about it.

 

There are some posts and techniques on here for doing it yourself if you're really intent on it. I may hit mine this summer, but even here with (normally) light snowfalls we get I'm not too concerned about it.
