restored my old scratched chrome trim!

Recommended Posts

I did not want to put the old scratched rain gutter trim back on so i restored it to a very acceptable close to new condition.

I started with a 100 grit sand paper to lose all the ugly scratches, sanded completely, then passed over again with the following grits, one at a time until perfect.

150 grit,

240 grit,

320 grit,

400 grit

600 grit

and then used a metal, aluminum polish.

I could have used one step higher(800) but that's all i felt like scrubbing!

Oh yeah! there's lots of it.

Nice work.

Just be aware that since you stripped off the anondized finish on there they will dull and fade periodically. You'll have to buff them up once in a while.

But, it beats spending hundreds of dollars for new trim, right!?

not in my opinion...frugal me tried that route...it sux a big one....it dulls more frequently than occasionally...it will dull at the touch....if you want lifetime maintenance i say go for it, otherwise, invest in a good used set or call blunt

It's not that tedious after all. I have polished my carb and it shines nicely for a few months maintenance free. A quick buff is all it takes. think of it as the oldie tradition polishing 'silver'. Also the reflection is deeper than that of anodizing.

no...just more grey hair...maybe that's why i appear different....

ok guys about coating aluminum....most, if not all clear-coats and or paints won't stay put on aluminum...unless you scuff it really well to give it a good tooth the prime with epoxy primer...if you want to polish it then protect it for mote than a few months and save a few bucks on wasted clear-coat spray bomb...buy some GLISTEN PC

it's the one thing i found that does the job...it's a 2 part material...it cures quicker in humid conditions and is best applied with a brush rather than spraying...if you want, it can be sanded and buffed like any other automotive clear-coat but it will take several days or more to fully cure

i stripped my rear window surrounds, polished them then applied glisten

I would think that brush painting the Glisten with the part you were painting in place would be a good idea since the paint probably won't like the flexing it takes to get the trim in place.

You can take your aluminum trim to an absolute mirror finish with these products by 3M:

http://www.ottofrei.com/store/product.php?productid=4019

start with

30 micron

go to

15 micron

then

9 micron

then

3 micron

At this point you are at a mirror finish after polish. If you want to reflect every photon in the tri-city area, take it on to 2 micron and 1 micron! (I have never gone past 3 micron.)

polish with this 3M marine product

http://solutions.3m.com/wps/portal/3M/en_US/Marine/Home/Products/Catalog/?PC_7_RJH9U5230GE3E02LECIE20S4K7_nid=GSTCY24D8BgsH8PTZGX97RglGSGZ6VKHDYbl

I did this with custom telescopes I built and got aluminum finishes like this --

from raw part (left) to 30 micron (right)

http://www.pbase.com/mclemens1969/image/68820093

at 9 micron

http://www.pbase.com/mclemens1969/image/68820136

9 micron

http://www.pbase.com/mclemens1969/image/68842893

3 micron unpolished

http://www.pbase.com/mclemens1969/image/68842910

3 micron polished

http://www.pbase.com/mclemens1969/image/68842915

super product and I only re-polished about every 3 -4 months, the marine product holds up beautifully. The entire sanding phase from 30 micron down to 3 micron is done soaked in WD40. This will not attract dirt the scratch pattern is practically invisible. It wipes down like a piece of glass.

polished wheel rims? I have a set that are polished but currently unprotected, and would like to keep them looking good. Does the product go on smoothly/clearly (no bubbles or brush strokes)?

TIA?
