Sanding Inside Of Exhaust Tips

I was wondering after seeing another tl like mine, Can i sand the inner part of the base exhaust tips where they are currently black, and make it completely chrome? Will it rust or corrode?

the exhaust tips are painted BLACK inside.
you sure can sand the paint off.
it will turn out shiny like the outside of the tips.

You guys are gonna say "whatever floats your boat bro" but I wanted to see what floats your boat.

I find polished gives it a unique look.
The only downside is that I have to use Bar Keeper's Friend on it often to keep it looking shiny.

As for having the exahust tips painted black, it gives it a sportier look.
No downside to it really as it's OEM LOL

I have a full can of Duplicolor High Heat Engine Paint in Low Gloss Black, ready to paint tommorow if polls are in favour.
I heard flat black turns out gray in the sun.

I need a mod to throw up a poll in here =)

What grit sandpaper works best that one leave deep scratches, but doesnt take forever to sand?

Bar Keepers Friend is the metal polish he used after he sanded, I just went through the OP and nowhere does it say the grit he used

I'd start with 400 grit dry and once you have the paint off move to 800 grit wet, from there you can either go to 1000 wet or leave as is then polish.

No need to use sand paper. Just use barkeeper's friend and some elbow grease. The paint will come off but it will take a while.

I did mine a while back, but I didn't get all the paint off.

A lazy man might try one of those polishing balls (like for headlight restoration) on a drill and skip the 'elbow grease'.

The bar keepers friend really will do what you need. I think I have a picture on the first or second page of my progress thread with my type s tips cleaned up that way, no sand paper used at all.

Bar Keeper's Best Friend is a mildly abresive surfactant used for cleaning pots, pans, and a number of other metallic surfaces. The stuff is awesome, I use it at home all the time.

Simply use some hot water and some paper towels. Much like wetsanding, periodically wipe the surface clean and reapply.

I love seeing that picture of my car lol

I used bar keepers friend with a rag and LOTS of elbow grease.
No sanding was done.
PITA when you're sitting in the hot sun too.

Make sure you wear gloves haha - I got blisters

Also, use something more than just a rag.

My tips took a couple hours, EACH. Sitting in the HOT sun.

Wow, that's why they look so great. I did mine in about 30 minutes, used a kitchen sponge and throw away gloves. Not 100% perfect, but they look good. Just need to wipe them down after each wash now to keep em clean.

Bar Keeper's Friend is the way to go.

I used the rough part of a two-sided kitchen sponge and it worked well without much effort. A great alternative is to use steel wool as some on this forum have found success using.

Here's a coupon for BKF (It's only $1.15 at my local Publix before the coupon!): https://www.hopster.com/offers/bar-keepers-friend/10

Ha. I would have tried the polishing ball if I had one. I gave up after 30 minutes in the Texas summer sun.

I got the majority of the paint off, just have to get the top inside corners on each side (those corners are pretty tight).

This what you were looking for? They haven't seen any BKF in awhile, this is just after wiping them down after a wash.

This is what I used also. The yellow and green sponge with a scotch brite type pad on the green side. Instead of BKF I used Eagle One nevr-dull metal polish and it turned out great in about 30 mins time

To be quite honest, I didn't realize I was taking paint off when I did it, I thought it was just dirty from the exhaust. After I did it though, I was happy with the way it looked. I doubt I'll ever bother re-painting them.

Absolutely not! Bringing attention to the 2" pipe transition to the large rectangular opening is just silly! Not to mention constant work for an awkward look!

No kidding. They needed a much deeper tip to hide the transition. I don't mind the tips, but you can instantly see they are just tips.
