This is getting out of hand...
I think Jtroutma can do his experiment without permanently damaging the card. If he wants to go through the expense of exchanging it, that's up to him.
If the card is damaged as a result of this, it would be ethically wrong to return it as defective: it was effectively, intentionally damaged. It would be similar to buying a car, crashing it into a tree (on purpose), then returning it to the dealership because it's "defective"...
Otherwise, it's up to the retailer to make that assesment.
What Megatron is saying here is that the petroleum jelly is only part of the solution. The neoprene is the other part. Not using both parts is very likely to damage the card. That's like crashing the car into a tree, and not putting on a seatbelt...
