Thanks Jimmy . Well,wet sanding sand paper can be had pretty easy , it can get expensive for what you get . I would try that . Wash & clean them as best you can , then I'd recommend doing a small section/spot from start to finish (wet sand w/like 300- 2500)to the underside of one of the tips . This way you'll know if this avenue will work , what grits work best ,what ones you can skip ,and if the final finish will be what you're after . Doing the underside albeit a b***h , it wont show if something goes sideways .
It sounds like a allot , like going from 300 grit all the way up to 2500 but you'd be surprised how quick you can accomplish both of those tips . The process isn't nearly as bad or long and drawn out as it seems . Least I did not find that . Specially because well, you'll get excited with each step, you'll see a noticeable difference getting you excited to see the next , then the final . It is very rewarding .
