last summer i did a quick but pretty good job using the herculiner bedliner stuff is awesome by the way but now its time to go over it again cos i didnt spend the extra monwy last time on the uv protectant stuff and it kinda fadded out and just needs to be touched up in spots..
my question is what is the best way to prep and clean the old herculiner before i go ahead and paint on the new??

 

wipe it with aceatone

 

get a bottle torch and a putty knife......have fun with that
