off of smoked Acrylic side window deflectors. I have 'LUND" on my new in-channel deflectors. What can I use to take the letters off without scratching or otherwise harming the plastic?

 

Unfortunately, nothing. Solvents will craze the plastic. Only possible is to carefully scrape it off with a hobby knife. We had some stuff when I built conversion vehicles that probably could had removed it, but that stuff is very expensive and usually only sold to companies.

 

arnt they vynal stickers? use a blow dryer

 

yeah, what 5 speed said, thats how i removed the decals off the paint and it worked very well
