Hey Guys,

Much like many people who have aspired to dream of a Sharp VZ2000....I too looked for a perfect, working VZ but wasn't ever able to find one.

As we search for these beast's we shy away from the ones missing control switches, but now you can get those made from Bredgeo, so there is no need to pray for a unit with all of those....

We search and hope for one that has a working turn table, but so many members have shown that not only can you still get the main drive belts, you can fix them yourself.

One of the other things we avoid like the plague is LARGE scratches on the front turn table plastic.....WELL NOT ANY MORE! :no:

I bought two VZ2000's in Japan and brought them home. One was in very good condition and the other so so :-/

The biggest problem with the one below was it had some GNARLY scratches in the turn table door plastic :thumbsdown:

The thing is, if you carry this radio with the front facing your leg, it's going to get scratched, there is just no way around it. This means the vast majority of these radio's is going to have scratches in them.

It's hard to tell from this picture, but there are some nasty scratches in the front....

So, I have a kit that is used for cleaning and brightening yellowed headlights on your car made by 3M.

Posted Image

Posted Image

Here is the plastic I started with.... :thumbsdown:

Posted Image

These kits are easy to use, you start out with an abrasive and work your way across the surface.

Posted Image

Each pad uses finer and finer sand paper....

Posted Image

The first sanding removes the big scratches....

Posted Image

The next one smooths it more....you can see it's still hazy, but no scratches.

Posted Image

Then after the final polishing with the pad and cream....It looks really good. I even did the inside with just the polishing cream. It really made it clear. :thumbsup:

Today I have done the second front plastic from the other VZ. Since I have done this once before, I have gotten a little better at it and this one is a clear piece of glass now!

It started out much like the other one....HAMMERED...

Posted Image

Posted Image

Sadly, I have avoided VZ's in the past that had scratches just like this on them because I didn't think I could fix it or find a new front piece.

Posted Image

Once again, going through the process.
All in all...it probably took me 40 minutes to do this....which isn't that made. If you consider it this way, if you spend $1,000 for a pristine VZ2000 to avoid bad paint and scratched plastic or pick up a slightly less "Ascetically Pleasing" one and do these types of repairs...you save your self BIG money.

Posted Image

You can see here it's coming along. It still has some hazing from the sanding....So...a few more minutes with the polishing pad and polishing compound.

Posted Image

Now you can see that is pure glass :thumbsup:

Posted Image

Posted Image

Posted Image

Posted Image

So, here is what I have learned....

When you buy a headlight lens cleaning kit follow all the directions....OH and practice first on the car!

The kit I have could easily do 3-4 cars worth of headlights, so I still have plenty of sanding paper and polish left over.

MOST IMPORTANT!
DO NOT USE A HIGH SPEED DRILL. This will burn / melt the plastic and then your :
I used a cordless, low speed drill and very light pressure. I was very patient and took my time.

I did have to go back a few times to work out scratches that I could not see until the last process. I also had to do the inside of the panel to make it REALLY nice.

In the end....anyone can do this....I know all you VZ guys probably have some level of markings so get out there and get'em polished up! :-D

Chris that looks friggin awesome!
I wonder if this technique would be too harsh for let's say a lasonic
Or super jumbo type of plastic decals
Maybe done completely by hand wouldn't hurt it?

I'm not sure about decals, since it probably would depend on how they are printed :huh:

Maybe Fatdog could answer that one!

Any auto part store should have them. The kit is used for removing the haxe from car headlights!

AWESOME INFO for sure!!!! :w00t: This is what the forum is about. The free exchange of techniques & iinfo. Too bad some members want to charge money for resources instead of sharing for free.

With the Plastic Polishing Posts bubbling to the surface again, I was inspired to do the dust cover on my Denon DP-30L turntable. I decided to do it at the kitchen counter so I could watch the Sox. I was smart enough to wear sacrificial clothing, but that's where the intelligence ended.
Now I'm debating as to whether or not I should buy a new coffee maker. :lol:
It is mostly plastic...Maybe I'll polish that too! :w00t:

Great job! Poor me!

I wore my joints using PlastX over and over. However the scratches were not deep at all. They were very light hair line scratches.

The cover came out like new but had joint pain for a few days. :lol:  :lol:

That's a brilliant tutorial. 

 

But I still can't imagine the process of scratching the whole area with a ROUGH sand paper first to remove a scratch.

What if the process doesn't succeed for any reason?

I need to do a trial on something to get convinced myself.

Basically we are removing a thin uniform layer from the total area of the surface plane, slightly deeper than the scratch depth. If one is not doing this thin surface removal uniformly it will leave patterns of the uneven wear of the surface. The foam under the applicator discs helps distribute the pressure evenly when it rotates. If one tilts the angle and apply more pressure it will make swirl marks and uneven wear. Good skill is required to make this work come out nice and evenly smooth.

 

The size of the abrasive media on the pads reduces to lower size finer ones as we progress to smoothen out.

 

Chris did a beautiful job!

Yes. I understand the process.

But need courage and skill to try it first.

This is one skill, I should develop.

 

Kudos to Chris for his wonderful restoration.

Just do what I did....practice on a relatively cheap car's headlights! Then work your way up to your grail  :-D Remember, you can buy replacement parts for your car!

Great Job Chris . A bit of elbow grease can make a world of difference :rock:

Knobs are a different story.

 

A few years ago a German seller had a VZ 2000 for sale an egay. He managed to make aluminium knobs for his boomer

 

I stored his e-mail adress for future use when i was able to get hold of a VZ 2000.

 

Unfortunately the PC where his e-mail adress was stored  died on me.

 

I'm not giving up though. Gonna try to find a place where the can fabricate them .

 

I know it will not be cheap but they will last forever :hmmm:

Aluminium knobs man!?! I bought mine from bredgeo, and they are great, but I would give my right nut for aluminium ones. Pardon my french. Please share.

 

Btw: Nice job on the front!

I have 2 VZ3500 covers. You have any polish left? If so, how much to do?

Being I don't have a drill. I would have to make an investment to do the job.

But I will keep an eye out for one in the future. Being I have to polish up 6 of the 777s :rock:

I do not have any more polish left, but one of those cheap headlight cleaning kits will work.

Has anyone tried this on plastic with LED lights behind it? I did it on my 5085 but I don't feel like it came out all too great, I may need to try 5000 grit. I'm also doing this by hand.

I've actually been doing plastic repair for years as an auto technician, but these small plastics are scary to work with! I actually used 3M professional 3000 grit on the box itself to clean up the 5085 then went over it with polish, came out great!

That's reassuring, I just got a packet of 3000 and also the 5000 Trizact yesterday, to see if could improve the surface on my dial windows. Some look like new but still have the slightest dulling on them, and it looked like this went a little beyond the 12000 micromesh pad.
