Undercoating Questions

I didn't use beadliner spray on my frame but I did use it for under my hood and decklid on my Regal plus they were both different colors.

I have had extremely good luck w/ LPS#3 that I bought by the gallon and sprayed it w/ spay bottle. Lately I have used Kimball Midwest corro-ban rust preventative that has worked as well. If you do nothing but spay it down w/ oil your ahead of the game

What is your goal with the undercoating? Prevent corrosion? Look pretty? Both?
