at trade school i was told by a lectocha that, holdens use 2 use a soft clear coat which wasnt as glossy as now a days,
the soft clear coat had less shine but had less chance 4 chiping, this was ideal because australia is a big open country with lots of high speed country driving, so there 4 the bugs that hit the car wouldnt chip the paint off because of that.
where nowadays since holdens has startd xporting 2 the usa they have changed the clear coat because of complaints from the usa, they where complaining there wasnt enuf shine on the paint and they didnt need the clear coat soft because its mostly citys and urban turrain, so holdens changed, now they use a harder clear coat which is way more shiner BUT it is weaker (chips easyly), this is ideal 4 the yanks but not 4 us the origen of the car, so all the new commies have hard clear coats on and if u take ur new commie out 4 a highway cruz or trip get ready 4 a lot of brush touching on the bar because of the bugs
