Hood Stickers, Arent they for information as recomended by NFPA? Of course they are, whether they mention any affiliation to any organization or not. Company name, date service, prescribed proceedure, affiliated organization, etc. All that info should be on there. But more than that its saying, Im proud of my work and want to let everyone who sees it that I was here. Also it is a liability issue which says , Ive done everything in my ability to clean it correctly, and I will be standing behind it also.
Isnt that little hood sticker like a "grafitti tag", saying , this is my turf? The general public is uninformed and could care less what affiliations you have. Sad but true. Quality work, professional demeaner, price is what they care about. Not alway in that order. As far as removing those other guys stickers, ten seconds with a sharp razor knife, install new sticker, done deal.
Ps: Rusty , You're not going to find any converts here. Coke , Pepsi, RC or what ever. You just keep reinforcing my theory of NPD.
