Avoid These Mistakes When Spray Painting Your Car

Posted on: 13 March 2017

You can repaint your own car with spray paint meant for metal; this can be done on the entire car body for a brand new look, or along one section to add a new coat of paint after accident repairs. While this is a difficult job, a car owner can do this on their own if they take the time to prepare the car and then apply the paint properly. Note a few mistakes to avoid if you decide to handle your own car spray painting, so you know the job will be done right.

1. Not cleaning the car properly

You may know to sand down rusted spots or other such damage to a car before painting it, but you also need to clean it thoroughly and properly. Any sanded areas need a good scrubbing to remove the dust and debris from the sanding, and the rest of the car also needs to be cleaned of dirt, mud, and the like. Wash the car thoroughly at a car wash but then go over it again with very wet rags so you can ensure everything is removed from the surface. You then also need to give it enough time to dry; overnight is usually recommended. Give the car one last polish with a clean, soft rag before painting so you know the surface is properly prepared. If there is any dirt or dust you pick up on that rag, the car needs another good cleaning.

2. Paint doesn't cover dents and dings

A good spray paint meant for cars and metal may cover minor scratches, but not dents and dings. Don't assume the paint will act as a putty or filler for any damage to the car. Run your hand over the surface and if it feels bumpy or rough to the touch, you need to sand down that area and potentially fill it before painting. Otherwise, the paint might collect in that dinged area and even begin to run while it dries, causing unsightly drips.

3. Dry between coats

Adding wet paint on top of wet paint is a good way to get drips and paint that is too thick. Don't assume that touching the spray paint to see if it feels dry is enough to know if the car is ready for a second coat; let the car dry in the sun if possible, but definitely overnight, before you add another coat. Not only will this ensure that the paint doesn't go on too thick, but you might notice that the colour gets darker or richer as the paint dries, so you may not even need a second coat.
