Hello all........generally i do not remove all.the paint from my end caps or cook box. I use a roll on paint to mask chips and blotches. I have found that HF brush cups just dont remove paint on end.caps very well at all..........i used.this today.......hopefully i can load a pic.......the paint just flew right off.....it did leave some scratching but i believe i will.be able to wire wheel the scratches away.
