How To Sand A Car
Sanding Your Car
How to sand your car? Sanding a car is very time consuming and takes a lot of concentration. First off you will need all the right sandpaper and a sanding block. Using the right sandpaper is essential when sanding a car down for a re-spray. For instance if you use a rough sandpaper it might be quicker but also you will run the risk of ruining the surface too. If the sandpaper is to rough you will notice the sand lines in the primer once applied and even worse you could notice the lines in your paint work once its sprayed on.
When sanding down a vehicle I would recommend using only wet dry sandpaper. This sandpaper is smooth enough but rough enough at the same time and when you wet it with water it gives a smoother finished surface. I have a lot of experience in Autos as I have rebuilt a lot of cars in the past. In this article I would like to explain sanding as I know it and I hope its helpful to you. In the picture on the left you will see my latest rebuild which is a Honda Civic. I ve just started this car and I will be writing about each stage of my rebuild so follow me for more hubs about this in future.
How I Sanded
When I'm sanding down a car I remove all the lights and fixtures first as it makes it easier and I don't risk marking them with sandpaper.When I was sanding down this car I used an electric sander for the car and sanded the awkward areas with sandpaper. I sanded the whole car using a 240 grit wet dry sandpaper. I find that this sandpaper leaves a lovely smooth finish after the old paint is removed. When sanding down a car the main thing to think about is getting the old paint as flat as you can and remove all the shine off the old paint. The car I ve done here was black which made it easy for me to sand away all the shine from the old paint and sand the surface flat.
Once you have all the old paint gone and the surface flat you should run your hand all over the car and see if you can feel and dents or dings along the surface. If you find any dents or dings you will need to pop them out and fill them in wit some filler. If you don't fill in any dents you will ruin your new car look once its re-sprayed as the new paint will magnify all the dents and will look horrid. If you have fibreglass bumpers you should check for cracks or breakages as well and fix them with a fibreglass repair kit or else the cracks will show up once painted.
Would you chance re-spraying a car.
Each section of re-spraying your car has a different type of sandpaper to use. I ve provided a list of sandpaper grits that i use when stripping and spaying a car which i hope will help you out when you tackle your first car rebuild. Remember always use wet and dry sandpaper.
240 Grit- I use this to strip the old paintwork, it leaves a smooth flat surface. I also use the 240 grit for sanding down my filler and fibreglass.
800 Grit- I use the 800 grit to sand down my primer once i have it applied and it is dry. The 800 grit leaves a smooth completely flat surface on the car which is essential as it will effect the finished paint job.
1200 Grit- I use this to get my shine once the final layer of paint has been left to fdry for 5 days. I use the 1200 because it is that fine that it flattens out the surface perfect so that when i buff the car i get a massive shined finish.
These are the sandpaper grits that i use and they work for me but every person is different and does things differently. There are grits ranging from 180 grit up to 2000 grit so there is a very good selection out there. I hope this article has helped you out and i also invite you to follow me and stayed tuned for my next hubs on the next stages of my rebuild
