plastic

Im curious if anyone knows if soda-blasting the grey plastic (ext) trim will make it look better or like new again? -Its solid color through the material right?

So yesterday I was blacking out my rims, grill, and emblems and opened the door for the cargo area and noticed the plastic was melting and didn't realize why and figured I would look at it later as it was only slightly misshaped...... later in the night me and my friends wound up driving really...
