1st - 4th March 2018 Continual improvement
One of the worst features of older caravans such as my 1978 Viscount is
the use of unpolished grey aluminium on the doors and windows. I know
that it is part of the look but when the aluminium becomes flat grey with quite
a lot of minor surface corrosion it spoils the over all appearance of the caravan
which is probably looking very smart elsewhere.
In my case I tried to get an acceptable finish on all the aluminium during my
restoration project. I used the recommended surface cleaners which I found left
streaks on the surfaces which needed another round of cleaning and polishing
to finally get an acceptable finish.
Over the next few month the old grey tired look returned even with the caravan
fully protected against the elements which made me determined to find the answer.
I decided that the best way to work on the doors was to remove the inner door first
from the main door by drilling out twenty or so rivets and then taking the
frame apart. I found that the various channels in the frame were full of forty
year old dirt, so I pressure cleaned the pieces before beginning the process.,
Firstly I rubbed the surfaces down with a green abrasive pad containing dish
washing liquid and a small amount of water. This was to remove any surface dirt and
easily removed stains. I then wiped the surface off. Next I applied some more
dish washing liquid and attached a 100 grit 50mm flap wheel abrasive to
my battery powered drill and abraded the surface in a straight line down the
length of the pieces. It is important to use an even pressure and try not to pause
along the length of the work to get the best finish.
Next I applied liquid Reflection metal polish and repeated the flap wheel process.
Finally I pressure hosed the work down, dried it with a cloth and buffed it by hand.
The finish is acceptable but not brilliant but I am satisfied that it as good as I can
achieve without giving the job to a professional polisher.
The final task in the restoration of Vintage Rambler was always going to be the
re spraying of the Sunflower yellow side panels.
I was quoted $200 to spray the panels if I did the masking and surface preparation
which I considered reasonable but I decided that I could obtain a very good gloss
finish spraying with British Paints, Spray Easy Paint and Prime enamel. The colour
I used is Sunpower gloss. The colour is almost exactly the same as the original.
I masked the aluminium and white borders of the work area and cleaned the surface with mineral turpentine prior to rubbing the old surface with a green 3M abrasive pad to
create a satisfactory key. I applied the second coat after the 10 minute drying time
and much to my surprise the finish is certainly as good as I would expect from
a professional spray painter. The paint cost me $36 and I have one almost full can
left over for future touch ups.
I have now run out of projects on my restored Vintage Rambler and look forward
to many more years of trouble free travel in this great country of ours.
