Little Tykes has thick plastic furniture and toys. Is there a way to make them look new? Buff, fill, what?
Buffing followed by acid etch (to restore texture). Overall a pretty rough job. You'll want to check the plastic type (found next to a 'recycling' symbol usually) for additional guidance. LDPE is common. Some people use heat guns, but for maximum potential entertainment value why not try a blowtorch? LDPE is actually pretty hard to set on fire.
