WD40 is no good as a penatrant,use PBblaster or kroil for that. ken ct.I am not familiar with the 32 hood latch but I would start with a very liberal dose of a penetrant like WD 40. I'd shoot it a couple times day for a few days & the start trying to work the latch & see if it will move at all. If that doesn't work then I would drill out the rivets (I assume there are rivets) holding it together & clean the parts up & reassemble & rerivet back together. Just an idea.
