A cautionary tale:
When I was 17 or so, my friends were all hanging out at this mall where kids would bring their hot rods to show them off. This one guy had a very nice barracuda, absolutly cherry, big hi-perf motor, and this after-market plastic hood with a big scoop over the blower, with four of those posts, one in each corner, to latch this hood down. Well this kid had these little padlocks through these posts, and sure enough, he went to start up his car and it back-fired and started something on fire and he paniced and couldn't find the keys to them locks, and we watched that 'cuda burn to the ground. Ever since then, I cringe when I hear of an actual lock that needs to be unlocked to get under the hood.
There's got to be a better way, but I don't know what it is.
'cause I need one too.
