How Much Aerosol Touch Up Paint Do I Need?

How Much Aerosol Touch Up Paint Do I Need?


Please note this is a guideline for a small to medium sized cars although it has been designed to be as accurate as possible cars aren’t perfectly proportional. Some bumpers are huge, some are small. One car may have a huge bumper in the front, and a small one in the back. Whether your car has a few scratches here or there or its entire paint job needs to be completely overhauled, a fresh coat of paint can make a world of difference to its appearance.

What you will need:

  1. Vehicle paint code. In most cases you will find the code located either under the bonnet or on the door frame. Take this to your local paint supplier and they will be able to match it for you.

Here are some quick tips that affect usage:

Choose a sheltered and well-ventilated location: Aerosols work best in warm, dry and sheltered conditions. Work inside a well-ventilated garage if it is cold and damp outside. Avoid humidity if possible as this makes it harder for the paint to dry.

Masking Up The area to be painted should now be clean and dry - any traces of dirt or wax can be removed using cellulose thinners. Mask off any areas not being painted using masking tape and newspaper (to avoid hard edges, increase the area to be painted by moving the masking tape back gradually as you apply each coat of paint).

Shake the paint can for at least 3 minutes: The pigments in the paint separate over time so you will need to shake the can vigorously to re-combine them. If you have already shaken and used the can within the last 12 hours you will only need to shake the can for 1 minute.

Test the paint on a spare piece of cardboard: Hold the can about 25 centimetres (9.8 in) away from a card and spray the paint. Check the card to make sure that the paint has sprayed evenly. If it is patchy, shake the can for a few more minutes.

Technique: How close are you to the car? Too close and it won’t be even, you’ll need more to cover the thin areas. Too far away and you’ll get some overspray and some of your paint will go downwind.

Paint Colour: Some colours cover better than others. Today’s lead free red, yellow, and orange don’t cover as well as paints from the olden days. Light silver doesn’t cover as well as grey, black, or white. Our colours have some of the best coverage on the market, but each colour may have different hiding properties.

Urethane: Urethane clear goes further than lacquer. If using lacquer clear coat please order 50-100% more product. This chart will soon be updated to reflect a better number. Apply two coats of lacquer, separated by a gap of 15-minutes. If the finish looks patchy, apply another coat of paint or wait until the surface is completely dry before rubbing it down and starting the lacquering process again.

This is general advice only. If pain persists see a professional.
