Self Leveling White Roof Sealant Dicor 501/502LSW

I actually ordered 502LSW but for some reason, was shipped 501LSW, A Newmar Moterhomes Tech said they use the 502 because it spreads out more vs the 501 I applied earlier M4 Note: The item description actually says 501/502. Sorry for the dual stock/spec. We primarily sell LED lighting, but keep some standard stock in hand here for walk in customers that need an emergency repair, but they do show online. On occasion we get an online order for it which we fulfill. I don't see any contact do us for resolution on this matter, but it appears it has been used at this point.
