A Question for LEOs about fingerprints

[DD977GM2]

So in the oilfiled I work will all sorts of people. One guy on my rig was a gangbanger and 10 years in penetentiary for murder a few others are felons of some sort or the other and then there are law abiding guys. Well one guy said if you spray WD-40 on stuff cops cant lift finger prints...just curous if this is true? Id think it would preserve prints to some extent.

EDIT: First off the guy that actually said the comment is a law abiding citizen and an avid shooter. Im surpised he doesnt know about this site or others.

The guy that did 10 years, IDK the whole story nor do I care. I do notice he is a hard worker and genuinely wants to make a better life for himself, but like the statistic says....80% go back. As for his lawyer, IDK the story and dont much care to.

I also think it is hilarious all the urban legends that are out there to thwart the cops or forensics and I even get all the mumbo jumbo about firearms and people seem to come to me about this or that on gun legends. I always seem to get the one that in vietnam the VC used our ammo through their AKs and to this day you can still use the same ammo for ARs in AKs. Fucking blows my mind on that one and people actually believe it. I also get the same thing....45 if it hits you anywhere your dead and blows you back on your ass. Do people not know physics? Folks in the oilfield are hilarious and just make me stop and wonder how much the public truely feels urban legends are reality.
