This mystery product achieved a mirror polish finish on my cast aluminum car part

what if I told you this started as a OEM

casted aluminum part and I was able to

achieve this mirror finish using a

product I purchased through

Amazon to show you I will first need to

remove the part from the engine this is

a cam phaser cover from a

vq40de from a Nissan extera I actually

take this motor out and put it in a new

engine from a 2018 Frontier so now this

engine is just laying on the side and

it's probably going to go to the

recyclers so I just thought I can get a

few more projects out of this engine so

to prepare this before cutting and

polishing the part I need to scrub it

down with d soap and water to get all

the oil and contaminants off of the

aluminum part just so whenever I use the

compound bars that there's no debris

that's going to be causing more

additional scratching onto the actual

part the product that I purchased from

Amazon is a six-piece

compound bar kit that is used for

cutting metal and polishing metal I have

never done any sort of polishing before

so I thought this would probably be the

best route for me to start I already

have a Dremel so now I just needed the

compound bars in order to use those two

items and start polishing on this

part based off my measurements these

bars are 3 in by inch and a

third I didn't really check the specs

whenever I bought the item but these are

the actual specs based off of my

caliper so this printed piece of paper

did not come with the Amazon product I

actually had to find this on a similar

listing on Amazon but it did not come

with this product but it does tell you

what each bar does which is going to be

very helpful for this

video the first compound bar I'm using

is going to be the black Emme which is

used for cutting and preparing the

aluminum I felt like this is the good

first bar to use to kind of create a

flat surface in order for all the other

bars to kind of do their job so as you

can tell the surface is all flat there's

no not much of a Sheen to it but you

could tell based off of before I even

used the compound that it's just a nice

clean surface now the next compound bar

I'm using is the brown trapi which is

still used to cut C through and remove

some scratches on the aluminum part

which I think when I used it it actually

created more scratches just far I was

being a little bit more aggressive with

it because I was just trying to get a

lot more of the pitting out of the

actual part I was trying not to stay in

one portion but I did use a couple

different heads uh polishing wheels to

kind of get particular areas where it

needed more work at so if you look at

these comparisons coming up the brown

try actually has more Sheen compared to

the black Emory the black Emory gave it

a nice surface finish but the branch po

actually is where it starts to kind of

bring out the sheen on the actual part

so the third compound bar I'm using is

called the white diamond it's used to

start the polishing process when I

started using it you could see the

mirror finish coming out of it and you

know once I start seeing that it did

take me quite a while to do the rest of

it a little bit over an hour just

because I was just trying to get every

single piece that I saw that had a dull

spot just using that white diamond and

cutting through the rest of of it and

you can see the results of this whenever

I kind of pull the screwdriver over just

to show you the slight reflection is

that a perfect reflection but you can

see that there's something there I mean

I didn't even bother wasting my time

doing it on the first two cuz you

couldn't see anything on the first two

but with this white diamond you can

start seeing the Polish come

through so the fourth bar I'm using is

called red Rogue it's softer than the

white diamond and creates a very high

Sheen and to show this I only did half

half of the aluminum part just to show

the difference between the white diamond

and the red Rogue and also while doing

this I took away a lot of the pitting

that was still there after doing the

white diamond which is weird cuz you

think you would cut most of it with the

last three bars but I end up using the

red Rog to cut down all the pitting and

I think maybe just because it's softer I

was just afraid to use any of the corses

ones and I feel like it was going to cut

through and make dips inside the

aluminum so I used the rest of the red

Rog to get all the pitting off the

actual part on the sides and the face of

it and then as you can tell on the

finish it looks a little bit greasy or

oily which is the reason why I use this

one as number four and not the fifth and

final

stage so the last and final compound bar

I'm using is called General green it is

used to create a high Sheen finish and

almost a mirror finish on aluminum so

from what I write up General green was

the best for aluminum parts for that

final finish and I don't believe it

leaves as much residue as the red Rogue

would so that's why I end up using this

one as the final product on this

aluminum part now as you can tell just

cutting right through it it's creating

that mirror finish that I was looking

for when you see these upcoming

comparisons the jle green has much of a

flat even mirror Finish versus the red

Rogue the red Rogue looks like it's has

some sort of lubricant on top of it it

it's very high and shiny but it's not

like the final finish that I was going

for for this aluminum part if you look

at the final results you can see the

reflection of my camera and where I have

it mounted at and now you're able to see

the finish on the screwdriver you can

see a little bit of pitting on the

surface of the aluminum part but you're

getting almost the reflection of that

screwdriver which I mean I am very happy

with the finish I got off of it so if

you're feeling inspired I do have an
