The cabinet and the head had absolutely no separation. I was very surprised. I did not have to get out my clamps and glue at all.
Well...I don't have any pictures of all the bondo work I had to do. I will just reiterate what everyone says.....
Apply bondo, let dry, sand;
Apply bondo, let dry, sand;
Apply bondo, let dry, sand; etc. etc.......until you have filled in all the divets, gouges, holes (I filled in the lock hasp holes and the holes someone had drilled into the side of the cabinet) and they are level.
I used 180 grit on my orbital for large areas of divets, but for the rest (corners, bottom and back box) I used small sanding blocks that I made up.
This took a week to bondo and sand the inside and outside of both the cab and head. I knew that the cabinet had to be perfectly smooth, because decals will show any imperfection.
Now, the bottom of the cabinet had a wood sheet that had some type of white laminate on it. It did not well at all. So I decided to colour the bottom. You either like it or hate it...I have to say I like it but would have preferred the natural wood look.
