The first picture is of Chris blocking away on the roof. Blocking is a technique to remove imperfections by wrapping a piece of sandpaper around a semi-flexible plastic block. The block allows the sandpaper to quickly remove material, primer in this case, from high areas until the surface is smooth and level. It is a dusty, tiring job, but it is the only way to get the perfectly smooth surface that the High Performance Finish requires.
If you read last week’s post about this car you may recall that I noticed a problem in the belt line on the car. Pictures two and three are of me working to correct that issue. Picture two is of me applying additional body filler and picture three is of me sanding it off, reshaping the body. It looks easy in these photos, but I did that apply and remove process four times until I got the line positioned on the car like I wanted it.
In picture four you can see Chris using the DA (Dual Action) sander on the less critical parts of the car. The areas that are not going to come under such close scrutiny and don’t have to have the mirror like High Performance Finish, like the cowl area, we finish with power tools to speed the process.
Picture five is Chris, once again, sanding, but this time in all the corners and crevices that the block can’t reach. Sanding in these areas requires strong fingers and soft hands … strong fingers to stand up to all the abuse from sanding … soft hands so as not put any ripples or other imperfections in the car from sanding without a block. But Chris can handle it because he is a sanding machine!
Picture six shows what happens after a lot of sanding occurs … you get a lot of sanding dust. The dust you see in this picture is the primer we sanded off today. This is the second time today the car has been blown clean with high pressure air … so you can imagine the amount of sanding dust we made today. In case you are wondering … it was a lot. So much we had to clean out the shop afterwards to get all the dust out.
The seventh and last photo shows the car after we finished blocking. We need to do a little bit of touch up sanding here and there, but the car is basically ready to paint in this photo.
I’m glad to finally see the car at this stage … and I suspect the owner is as well.
