KR> Does a VW block need paint?

[Gavin Magill]

Hi Darren

If you decide to go ahead with removing the paint from your block can I
suggest you possibly look at sodablasting as an option.
This method was recently mentioned at our local SAA Chapter meeting (NZ
Sport Aircraft Association) and one of the members wrote an article for the
Chapter newsletter.
Part of the newsletter article goes as follows.

"Baking Soda (Sodium Bicarbonate) is commonly used as a leavening agent in
cooking and those who have dealt with battery corrosion will know it as an
excellent alkali to kill acid and clean up the corrosion. I could not
determine how long Sodablasting has been around but it seems to have been
brought to prominence when used as a cleaning method on the Statue of
Liberty in the late 1980's where a non-toxic cleaner was required."

"Google-ing ?sodablasting? brought up many articles and I suggest using that
forum for those of you who want more info. According to Wikipedia:"

?Sodablasting is a non-destructive method for many applications in cleaning,
paint stripping automotive restoration, industrial equipment
maintenance,rust removal, grafitti removal, molecular steel passivation
against rust, oil removal by saponification and translocation, masonry
cleaning and restoration, soot remediation, boat hull cleaning and for food
processing facilities and equipment."

The newsletter article can be found on page 13 and 14 of the newsletter
which is published here.

I personally have no experience using the method but thought it might be
worth a look.

This may be of interest to others on the list.

Regards
Gavin

I know almost everyone paints their blocks but it is not a good idea.The paint 
helps retain heat in the block.

Hi John,

The std beetle block is mag ally although there may be non mag cases out 
there.Mag cases should definitely be painted as moisture dissolves magnesium 
which gradually weakens the case. That's why mag wheels are always painted. 
Possibly not an issue in El Paso.

See the following

Shiny ally actually radiates less heat than a black painted surface, engine 
paint is designed specifically to disipate heat.

Darren,

As a long time VW builder (40 years) I recommend you remove the paint. All 
paint acts as an insulator to some degree and the last thing a VW needs is 
more heat. I have always kept my engines bare and those of my customers.

My old 1835vw has peeling paint on it.
Is it really necessary to have the block painted?
Is there any safe way to strip it off or is a wire brush my only option
besides a walnut shell blaster?
