The little workshop is back in full use so I decided to restart my experiments by side-by-side trialling various polishing and coating products. Some of these products are mentioned on other threads - adding here for a simple side-by-side comparison. Several of these products I have never used on Bakelite and under normal circumstances, just my preference, would not.

This thread will be updated once each trial stage is completed.

Each trial will consist of just one single application of the product undergoing comparison testing.

Each of the products will be applied for a duration of up to one minute following it's application instructions. Some products are much quicker to apply (eg: Aerosol).

Any product requiring a drying (curing) period will have it's 'after' photograph taken at the end of that time.

The one minute time limit includes the initial Step 1 prep work. Any areas requiring more work under other circumstances will remain as is.

These results are as found on the day of each trial - your results may differ.

Clear Gloss Aerosol Varnish

Pros:
Quick to apply.

A single application produces a notable sheen. Reflection detail is more defined (none coated area shown to right of red line).

Fingernail Scratch Test left no mark.

Cons:
Durability in use unknown.

Unoriginal/none factory coating.

Over application will result in runs and smearing requiring total removal of product and start over.

#2
Liquid Gloss Acrylic Varnish

A milky white substance with a creamy consistency. Dries clear.

The initial microfibre cloth application didn't coat evenly, so a second area was coated using a cotton cloth, which covered better. A third area received a brush application.

Green area - brush
Yellow area - microfibre cloth
Red area - cotton cloth

Pros:
Easy to apply.
No strong odour (plasticky odour)

Cons:
Application by brush can be streaky resulting in uneven application.
Too thin an application by cloth can result in the product being immediately wiped on/off.

Fails finger scratch test. Multiple scratches will flake product off surface.
Long term durability untested.

Unoriginal/none factory coating.

Some sheen when dry - looks better from a distance.

#3
Yacht Varnish

Pros:
None

Cons:
Strong odour - apply in a well ventilated or external work area.
Thick consistency and tacky to apply.
After two days - dry to the touch but not thoroughly cured.
Air bubbles lifted to surface during drying/curing.
Density of product means application is thicker than required. This resulted in runs.

Failed scratch test (image 3). May become more durable over time when hardening has completed.

Unoriginal /none factory finish.

Not recommended.
