Spray Finish

[lionsinthestorm.livejournal.com]

Sorry if this is somewhere in the memories and I couldn't dig it out >_<

But I am in the process of making a gift for my boyfriend (aptly named "porn shelves") from one of those cheap plastic shelving units. I spray painted the outside, but the paint keeps chipping and it's a pain in the ass. I got a spray matte finish but that doesn't really seem to keep it from chipping. Does anyone have any suggestions as to a finish I could use (preferably spray) that would keep the paint from chipping off of a plastic surface?

Thanks in advance, and sorry for text-only. Maybe I'll post some pics when I'm done.. X-rated ones. (On a side note: some porn is just weird..)
