I would Blue tape the edges of the wrap on both sides, useing a throw-away stain brush, (spun out well dry)I would put contact cement on a scrap surface/container and load the brush, then brush it well into the lift (thin is better), allow to dry five minutes and hand smooth them down from the middle to top, then middle to bottom. Then useing a seam roller, again from the middle to top HORIZONTALLY and middle to bottom HORIZONTALLY.
Think it out and each seam will take six minutes with drying time !i Each time you re-use the brush, it will soften again unless an hour has passed !i
