I had to read it 3 times to work out what you were talking about...lols Expensive way to redo plastic...Im sure it works fine,especially since its an oil But its also a soluble oil and will perish when weathered...I find lanolin and silicone work fine:) And btw I take fish oil every day for joint pain...and it works fine:) I reeally hope Im on the right track here cause im still not entirely sure what this post is about....My meaning being...what plastic did you actually rejuvinate? lols
