Over the past 2 Saturdays I've had the unenviable task of hand stripping all the layers of old paint, primer and filler form all the aluminum body panels of my BN1.
While the main chassis and the outer side fenders and doors are all steel on my car. The front and rear shrouds as well as the bonnet and boot lid are made of soft/light aluminum.
The steel components I've decided will be sent out for sandblasting at Jetstream Automotive. Jason Stoch of Jetstream reviewed the process with me and explained that they only use fresh wet sand that actually contains a rust inhibitor in the liquid part.
This way, the heat/distortion is greatly reduced from the sand being wet.
The aluminum however needs to be treated very delicately. Any sort of blasting process will distort it.
So I'm left with either chemical dip stripping (which is very expensive and not available here on the island) or stripping the paint by hand...
So in preparation for the task, I first prepared my work area with some large poly tarps spread out on the floor. I rolled the car over the tarps and partially mounted the aluminum shrouds in place on the car.
I purchased some large tins of paint stripper - I recommend getting the gel type that stays wet/active for longer.
Then I armed myself with some heavy clothing that I don't mid destroying, some goggles, gloves, a respirator and some good hand tools for stripping -
I found these 3 tools to be the most effective:
-I start by globbing on the stripper heavily with a brush, I would wait about 10min for it to start bubbling the paint.
-Then I would use the big scraper to remove layers of paint.
Because my car had several layers of different colours, I had to re-apply stripper often to work my way through the layers.
-When ever I encountered any filler, I found the razor blade scraper to work best.
-Once I was down to basically the metal, I would scour the remaining residue off with the big wire brush...
Here are the results on the front shroud...
And again on the rear shroud...
and finally the bonnet -
and boot lid...
As you can see, I was quite happy to discover that all the aluminum panels are in great condition with almost no corrosion at all around the outer flanges (as often happens).
However I did find lots of dents that had been filled in with loads of filler. All the dents are going to need some careful working out.
The bonnet especially looks like someone probably laid on top of it!
Perhaps my car was once used in some publicity photo shoots with models laying across it?? - perhaps that's my bright imagination again...
Until next time -
