Undercoating opinions needed

[S3B3AST]

Hey everyone, Im looking for input on PR-15 (?) undercoating. Im thinking about using it on my frame/differencials/leaf springs. Has anyone ever used it or seen it in person? Im thinking this or powder coat. Powder coating costs a little more than I want to spend though. Im interested to see what everyone else has used. My goal with this truck is for it to become a daily driver. Its already in pieces and ready to go, all I need is a decision. Please help...
