Hi, ;D
I seen on more picture in  Internet, That some black parts are plus glossy.
For example the Frame is glossy instead other part's are minus glossy.
I think that in origins the frame was painted in a mode and others parts, powder painted.
What do you think?

Hi friends, ciao amici  :P
recent works.....
In Italy we use Tankerite, is a good bicomponent product for tank's .
So, in the last motor show (circuit of Imola), I buyed Tankerite.
To this link You can see a video.

The procedure is simple and is very important follow the indication's.

to the end is nice to see, inside the color is red and hard.

Much discussion (in past) by several members on paint subject;  member concensus believes no powder coat.  If i remember correctly, members concensus believes switches and master cylinder are anodized.  The upper steering clamp is approximately 70% gloss black.  Frame gloss black(not deep gloss.)  Other frame parts less gloss.

Hi Maurizio,

Is Tankrite a product available in Europe ?  I did a websearch and could not find info.  I have no opinion, i don't know anything about the Tankrite.  In video, appears quite viscous.

In USA, we have a product called Kreem.  I've used Kreem in several tanks over the past 30 years.  Kreem is methyl ethyl ketone (MEK) based.  Kreem requires a perfectly clean tank with all rust removed using a weak phosphoric acid prep.  I have seen a number of tanks where Kreem was used and over the years the Kreem coating let loose, hanging in tank, even when tank is prepped properly.  Kreem is not easy to remove, only by using multiple baths of MEK.  Also, coating with Kreem, the thickness of coating difficult to control, because Kreem is rather viscous.  Kreem cautions against too thick coating, but difficult to control because of viscosity  http://kreem.com/

Recently A couple years ago, i learned of new product, POR-15.  I used in badly rusted tank on 2157.  (Elsewhere i posted my experience removing the rust using washing soda and electrolysis, which REALLY removes all rust extremely effectively.)  Then i used POR-15 for the first time, a coating that reacts to bare metal and to any remaining rust.  POR-15 is not MEK based, but the coating is essentially clear and virtually non-detectable after application.  I was VERY pleased with end result using POR-15.  Coating thickness all the same; POR-15 is not viscous like Kreem.  http://www.por15.com/whatispor15.asp

These are just my thoughts and experience.

Steve,

i've visited the Kreem  site.

The Blue Shield product can be a care preservation for the Lotus Root.

What you think about?

Hi Steve,
In this moment I'm to work  :-\
Ok....... ::)
In Italy, many person buy tankerite for restoring the tank.
This is a famous  product in Italy.
In every box there is a bottle of tankerite, catalyst and phosphoric acid (in low percentual).
After the mixing Tankerite is still creamy and is necessary apply 5-10 % of alcool.
In this mode Tankerite becomes very liquid, with perfect application.
After many years I saw many tank's  in good  conditions.
Attention, after the application is necessary to wait one weeks for use.

Please see also this web site:

"Is in french language, but You can use google for translate"
This is a similar product of another famous  brand

Bye   ;)

Hi friends,  work go on...

Now is the time for the paint frame, my ultimate opinion (after many brainstormig) is for powder paint.
Near my home there is an important factory specialized in paint.
They prefer apply before special primer (anti corrosive) and after powder paint.
They offer warranty for them work.

Some pictures..

I am very happy, I think that the glossy is good

After the frame painted I decided to bring the engine to my friend (for disassembly)
For me is the first time, I don't want do mistakes.
He is specialized to disassembly the  engine, very good man :)

Sorry, I forgot.....

Also the Carbs must be restored.

Where I work there is ultrasonic bath, this is the better solution for wash the carbs.
Before to insert the carbs is necessary put the special liquid in the water and to warm

before the bath...

After the bath I saw the the color is changed.
Some halo of blue/purple is possible to see now.
