Is there any reason for the red and yellow pain on the lugs and studs of the p1k ? I swapped out my base model 12” steels for a set of deluxe 14s. My steels had open ended lugs with red paint on all four studs. The deluxe 14s I put on came with the lugs that have red pain on 8 and yellow paint on the other 8. They all seem the same.
