Title: What is this and how do I get it off!!
Post by Arty Dodger on 12/06/16 at 17:36:45

What is this and how do I get this off?  I've tried steel wool, polishing and rubbing compound, buffing with drill, and scrubbing.  Anything I'm forgetting?

By the way, that's after I scrubbed with all the above.

Please tell me that's not the clear coat.  That means I'll have to strip it down to bare metal and polish.  That could take a while...oh well I guess I needed a long term project.

That looks like the clear coat or the aluminium is pitted.  I remember a thread about this.   Search the forum with those keywords.  I prefer the Google and adding site:suzukisavage.com

Yep, that's clear coat and there is corrosion forming underneath

And.....the corrosion gets pretty deep when you see the white turn to black.

Do you live near the ocean and salt air?

If you strip the clear coat, and then polish....you will have to polish it regularly to keep it from corroding again - especially if the bike gets wet often.

Anyone ever strip, steel wool and clear coat stuff like this to restore the factory finish?

Yes. I did just that to the left side(stator) cover on my bike. It looked pretty bad when I bought the bike. Lot of black spiderwebs under the clear coat.

I used VHT brand Strip Fast, polished the cover with Mother's Mag and Aluminum Polish. and then resprayed it with VHT clear Engine enamel. That was a couple of years ago and it still looks fine.

The most time consuming part was the polishing because I did it by hand. A little buffing wheel would probably have worked and been faster but I don't have one.

I used a small orbital sander and 3M Green Scrubby pads and a spray bottle of water on the engine side covers.. worked great.

Thanks for the tips guys.  I might have a need for a "factory like finish" on my project.

I shot clear on it. Looked great.
If you have a small orbital, hit something with it and look at the pattern. You might be happier with a chemical strip.
Cheap, rattle can clear isn't the same as automotive.  
Some guys here can point you right. Not me..

I tell people Longview, but I have a Gilmer address, but, I can be to the Longview mall in half the time it takes to get to Gilmer, and once In Gilmer, you pretty much need to go to Longview if you want more than groceries, hardware or a veterinarian.
I went to Shreveport the Saturday the time changed. Played some Beer Pong, maybe the world's most unsanitary publicly played game.

You could get them powder coated....that sure would be a lot of time spent in doing the prep work.  The forks would have to be taken apart completely, all oil would have to be cleaned from the inside, the existing coating stripped, the legs bead blasted and then baked.......and then you have to put it all back together again.

Title: Re: What is this and how do I get it off!!
Post by justin_o_guy2 on 12/07/16 at 11:24:08

And the powder coat must not be allowed IN anyplace you don't want it.

Perhaps clear anodizing?

Years ago, when I worked at a Honda shop (about 45 years ago!) we tried everything back then and couldn't get the clear coat off - it was more than a simple paint clear coat, it was much tougher.

I am sure it can be done though!

I just got a call from the powder guy that my lowers are ready.  Dave is correct, it was a LOT of work.  Hopefully it'll be worth it when re-assembled  ;D[/quote]

Was just confirming that disassembling the forks really is a lot of work for the aesthetic upgrade...  if I had it to do again, I probably would have tried some of the other means of cleaning mentioned in this thread first.  

But here's a little more info in case it's meaningful:

He does fantastic work.  Sorry I cannot say what the cost was as the fork lowers were a part of a larger job and I didn't get a cost per item breakdown.    

Hope that's helpful  :)

Two questions. 1. Does the whole crankcase have clear coat as well as the forks and probably triple tree, 2. What is the best way to keep it in good nick, wax or some some other treatment? I do live near the sea but it is not ridden in the rain.

Title: Re: What is this and how do I get it off!!
Post by zipidachimp on 12/08/16 at 01:07:08

for the forks: rattle can primer and black hammertone. lots of masking tape! 8-)

Title: Re: What is this and how do I get it off!!

Sand them and paint them black.

The center cases are painted or powder coated with either silver or black, and it is pretty durable.

All of the brushed aluminum parts (the ones you mentioned plus the wheel hubs and brake hub) have a finish that is polished and clear coated - unfortunately the clear is not very durable for some reason.  When the clear coat becomes nicked, cracked or violated - moisture gets underneath the coating and corrodes the aluminum.  (The rear pulley hub has a silver paint/powder coat in it).

Washing and thoroughly drying the bike, and keeping it waxed helps.  Bikes stored or ridden in damp environments are going to have the worst corrosion problems.  Waxing is likely to help seal any surface flaws in the clear finish.

Maybe the coating durability issues are why the covers and lower fork areas are black for 2017.

Title: Re: What is this and how do I get it off!!
Post by ohiomoto on 12/08/16 at 10:02:04

If you google "clear coat over aluminum" you'll see that traditionally is a difficult process.

Post by ditz on 12/08/16 at 16:03:18

I don't know about the history of clear coating aluminum but Borg Warner did thousands of AL. locking hub covers.  :'(

Post by philthymike on 12/09/16 at 13:29:03

I have this same ugliness on my crankcases too.
my S40 is an 07 and it's a shame the clear coat couldn't even last 10 years.

Title: Re: What is this and how do I get it off!!
Post by Rodger on 12/11/16 at 08:15:45

This thread motivated me to clean off the lower fork legs & engine covers, then apply 2 coats of Turtle Wax. Hopefully that will help seal any tiny holes in the clear coat and prevent the creeping corrosion.
