Finish van build

I need someone to finish my van build. Most of the work is done but there are 2 hard to cover spots that I don’t want to look bad if I do them. The spots are around the top of the sliding door and around the top of the back doors on a promaster van. Also, I have an issue with drilling a screw through the side of the van that lets water come in. It has not been resolved and that wall panel needs to be taken out and be redone but I just found the hole and plugged it temporarily. The panel is from floor to ceiling and the with of an arm.
