I'm going to suggest your friend used too much or maybe sprayed them over another paint that wasn't fully cured causing a bad reaction.
From what I understand Testors makes both lacquer and enamel sprays. Lacquer thinner can theoretically melt plastic but you shouldn't be applying so much and so quickly that it actually creates a noticeable melting (it's actually part of what makes lacquers so tough, they're actually biting in to the surface). Tamiya sprays are also lacquers, as is Testors Dullcote which people have used for years to clear coat their models.
