The left side of the bonnet is after I have spend time sanding it down and right side was the original state when I got it. The lacquer were peeling off in spots all over. My plans was to have it spray-painted so the condition didnt bother me much. However, I decided to try to restore it for fun (So I thought)
I used a couple grade of sand papers: Grit 240, 500, 800, 1200 & 2000 for the job.
During the sanding job, always do it in a single direction for each grade of paper. eg. Up & Down or Left and Right. Basically, just sand it in a perpendicular direction to the previous grit.
This is so that u can see if u had managed to sand down the area properly. If u did, u should only see the sanding lines in the same direction.
This is the result after grit 240 sand down.
I did wet sanding for all the different git of sand paper. Basically just wetting the surface and sand paper with water regularly.
After I got down to grit 2000, I use rubbing compound to buff it with a DA machine.
This is the final result, not a fantastic job ;p. Total time spent 10 hours.
The comforting thought is that at least I know I got the foundation done right before sending it to the professional for respray!
