The first thing I worked on was the chassis.

I hand brushed Testor’s Metallizer Steel and Aluminum on various parts of the chassis. They were then polished with Alclad Aluminum Powder. The exhaust was painted Metallizer Exhaust (what else?) and the suspension painted steel and black.

The interior was painted various shades of RLM 66 Scale Black (actually a very dark Gray) and RLM 22 Night Black (a true Black color). The instructions say that the back of the seats were painted a polished steel color, so on went the Metallizer and Alclad Powder. Various portions of the interior were also accented with Metallizer prior to final assembly of the interior.

The Hard Part

Now comes the hard part.

A portion of the lower rear of the body curves under the chassis pan. Revell chose to mold this as a separate part to be added after the body is painted and the chassis is attached.

Revell’s mold makers for their car kits aren’t up the standards of their other mold makers. The body panels required a lot of sanding to even out all the high and lows and the sink marks had to be filled in. With this in mind, I figured that the added lower body panel would leave a giant seam. I didn’t want to have to work this seam after I had painted the model. I decided to add the chassis, sans wheels, and glue the lower body panel in with lots of CA.

I sanded the seam smooth over the period of a week, sanding and filling for about three hours each day. Whew! I also sanded the join between the broken body panel and the rest of the body as smooth as I could.

This was the toughest painting job I have ever undertaken. I knew I wanted a mirror smooth surface, so I did a lot of experimentation. I used some car polish to buff the bare plastic smooth.

I polished the surface until I could count the number of light bulbs in the ceiling fixture above my head using the reflection off the plastic surface. I sprayed Testor’s Aluminum Metallizer from a spray can and polished the model smooth. I wasn’t impressed.

I tried to polish this finish with Liquid Luster (LL) car polish and ended up eating right through the paint to bare plastic. Arrrgghhhh. I sanded everything down again and re-polished the bare plastic.

This time I tried Tamiya’s Gloss Silver Spray. I had used Tamiya’s Gloss Black with very impressive results and hoped it would repeat that here. Nope. No go. The paint dried rather dull and had a lot of dust particles and clumps.

I sanded this down again with some 1200 grit and sprayed a few more coats to see if I did it wrong. I ended up allowing paint to pool and had puddles of silver flakes. Drats. I sanded this smooth and tried to polish this paint job with the LL again.

I had done this successfully on the gloss black paint of another model and hoped beyond hope to fix this one. Nope. The LL ate the Tamiya paint down to the bare plastic again. ARRRGGGHHHAAARRRHHHGGGG……

BMW Z8

By this time I was ready to throw the model against the wall, but I realized that I chose to work on this and I’m not going to give up on it. It was James Bond’s last BMW after all! This time I carefully sprayed three coats of Tamiya Gloss Silver, sanding each coat smooth after letting each one dry a week. Then I got two cans of Tamiya Clear Gloss.

This is great stuff! It dried hard in minutes and was almost as smooth as glass. One coat, two coats, so far so good.

As I set the model down to cure after the second coat, my finger brushed the wet lacquer.

The wet lacquer softens all the layers of paint down to the bare plastic. My little finger brush exposed the white plastic! Where’s the wall, Where’s THE WALL.

I set the model down and went far far far away for a few sessions with my psychiatrist (a Chihuahua named Dolly, there is no psychiatrist in the world like a puppy licking your face.)

After sufficient time, I went back to the model, sanded the offending area down (again and again), re-sprayed with silver, re-glossed with Tamiya clear and very very very carefully set the model down. After three more coats of clear, I felt I was ready for the Liquid Luster. I polished the Clear with an old T-shirt and LL and this turned the surface in to glass.

Yes! Finally something went right! I polished the entire model free of orange peel using the light bulb reflection technique again. Basically, I have a fluorescent light bulb that bends back on itself to form two narrow bulbs. On most gloss finishes, I can see only the reflection as one bulb.

On highly polished gloss finishes, I can see the dark area between the bulbs. In areas of orange peel, the image is disrupted. It’s a neat and helpful trick.

I then dipped a T-shirt wrapped finger into a bottle of Alclad Aluminum Polishing Powder and proceeded to rub it into the LL surface. This produced a brilliant and highly reflective silver surface. Great!

I sprayed a coat of Tamiya clear to seal the high gloss finish and promptly lost it. ARRGGhhh (a not so aggravated yell this time.) I pulled out the LL again, polished this surface again and re-polished with the Aluminum Powder. I polished the surface five times with the powder, each time the silver got deeper and deeper.

Kakoi desu yo!!

Most women like shiny things (I apologize for this generalization, but this does lead somewhere), gold, silver jewelry, and yes, shiny new BMW models. My girlfriend walked into my shop and saw my mirror like Z8 on the desk. She picked it up by the doors and turned it over to look at the underside.

I caught her putting the seats back in after they had fallen out. I yelped (eeek) and promptly and gently took the model away from her beautiful little hands (YANK. “Mine precious, Precious!…”in my best Gollum voice). Of course this finish is not the most durable finish, and she left some very nice clear fingerprints in the metal polish.

The grease from a fingerprint doesn’t polish out without the use of chemicals. All I could do was break out the Liquid Luster, polish out the grease, and rebuff with the Alclad powder. Oh well.
