Jack I know how you feel, I have a '94 Olds cutlass sierra that developed a crack and the clear started pealing off on the hood due to water buildup. Me being lazy and the car wasn't that important to look good so I just got me a peice of white duct tape I used to use on my race car and slapped it over the crack after it dried, problem solved
You might just want to sand it off with some 120 with a DA it might take longer, but it would be much safer than trying to manover a razorblade between coats. Or if you have a really good air compressor a set of safety goggles and a pinhole air chuck you can turn up the air pressure to about 90-100psi and peel that crap off. I've done it that way twice, its kinda fun, but but can get very loud, use ear protection. You can get a pinhole air chuck at a harware store, it looks like a pen or pencil and usually made of brass and it has a twist nozzle for varying air pressure. That one of my favorite tools
