The Model 3 Fender has deep curves, so our kit was designed with 2 seams so all the pieces lay flat. We start by laying Piece A and tack 3 points with all the major alignment points in mind. Then we squeegee all the slip solution out from the top and the bottom. We butt seam Piece B to Piece A with 3 tack points as well to make sure alignment is solid. Then we focus on squeegeeing out the rest of the slip solution. Lastly, we start Piece C by tacking both ends and then butt seaming Piece C to Piece B to complete the fender install.
