Tom,I'm not beeing a smart-a$$,but how long has it been since you have sprayed the organisol ? I'd like to see the hood after 10 years, if you have catalized version, it should be fine, but if it's raw lacquer,I don't think it's such a good idea to lay on so many coats especially wet on wet,I wouldn't touch lacquer with a 10 foot stick,but that's just my opinion
