I don’t know about the older flares but the newer ones from RC def comes with the rubber seal and 3m on it already i have received 4 pairs and they all had them . YES 4 long story lol but just keep in mind the newer version flares comes in 2 pieces where it matches the line that is coming from the corner of your headlight to the bottom on your fender . I just need bigger tires n rims also I’m lifting it 4 more inches from stock trailboss
