Nice! Sounds a lot easier than my method... Had my father-in-law machine away the black on my Bosley cap and then ADD knurling.
ok so, i got home super late today but there was still sunlight out. my praco has the black knurled cap. it has knurling all the way around, it doesn't have the holes drilled. but it is anodized black.. so its the right looking cap except its black instead of raw aluminum
i was reading all night last night that oven clean removes it, so since there was some daylight left i decided to give it a go. i usually take plenty of pictures but i was in a rush to beat sundown.
i went to the recycling bin and grabbed a tin can ( corn ) i washed it out and put it on my work area outside. then i tied a string to the spring on the end of the praco cap. so now the praco end cap is dangling by a string. i got a milk jug and cut the top off and filled it with warm soapy water, and grabbed a rag along with rubber gloves and a wire brush.
i sprayed the oven clean inside the clean corn can until there was about 1" of foam. i then dropped the cap in it holding the string so i can pull it up and check how much anodize is left. to my surprise it was like instant the second the cap touched the foam! i would dunk the cap in the oven clean foam, then dunk in the warm water. i did this roughly 10 times. in all honesty it was less then 1 minute of dunking. this i timed because i didnt want to burn the aluminum like i purposely did on the V2 to show age
during these dunkings towards the end the black anodize was still inside some of the knurling, not to much but enough to be noticeable. i just hit it with the wire brush and done. like i said no more then a minute. it looked alittle dull, but i think it was just the age of the aluminum, so i then brought it inside and filled the sink with warm soapy water and hit it with scotchbite. brought it right back to life. i will post a finished picture tomorrow
i just wanted to share with everyone if you see a praco in the future with the black knurled cap its not the end of the world, that black anodize falls right off with oven clean!
good luck
