Aerosols vs Spray Gun

Aerosols vs Spray Gun – Which Should I Use?

Choosing between aerosol paint and a spray gun depends on the size of your job, the equipment you have, and your experience level.
Both methods can produce excellent results when used correctly.

This guide explains which option is best for you, and what to consider before buying.

Quick answer

Aerosols – Best for DIY repairs, single panels, small areas, and beginners
Spray guns – Best for full resprays, large jobs, and experienced users

For most home users, aerosols are the easiest and most practical option, especially when using custom colour-matched paint.

Option 1: Using Aerosol Paint

When aerosols are the best choice

Aerosols are ideal if:

You are repairing one panel (wing, door, bumper)
You are working at home or in a garage
You don’t have a compressor or spray booth
You want a simple setup with minimal equipment
You are new to painting

Modern professional aerosols can achieve excellent finishes when proper preparation is followed.

Advantages of aerosols

No compressor or spray gun required
Quick setup and easy clean-up
Easier to control on small areas
Lower upfront cost
Ideal for spot repairs and blending

Custom colour aerosols

We supply custom mixed aerosols matched to your vehicle’s colour code.

This allows you to:

Achieve an accurate colour match
Avoid mixing paint yourself
Repair panels with confidence

Custom colour aerosols are one of the most popular choices for DIY bodywork and panel repairs.

Limitations of aerosols

Less efficient for large areas
More cans needed for full resprays
Slightly less control than a spray gun for experienced professionals

Best suited for:
DIY repairs, single panels, touch-ups, and beginners

Option 2: Using a Spray Gun

When a spray gun makes sense

A spray gun is better if:

You are respraying multiple panels or the entire car
You already own a suitable compressor
You have experience spraying paint
You want maximum control over paint application

Advantages of a spray gun

Greater control over paint flow and finish
Faster coverage on large areas
More economical for full resprays
Preferred by professional bodyshops

Things to consider

Using a spray gun requires:

A suitable compressor
Moisture traps and air filtration
Mixing and thinning paint correctly
More space, setup time, and clean-up
Proper ventilation and PPE

For most home users, this setup is unnecessary unless carrying out regular or large-scale painting.

Which should you choose?

Choose aerosols if:

You are fixing rust
You are painting one or two panels
You are working at home
You want the simplest and safest option
You need a custom colour match

Choose a spray gun if:

You are painting most or all of the vehicle
You already have the required equipment
You are confident mixing and spraying paint
You want a professional workflow

How many aerosol cans will I need?

As a rough guide:

Wing or door: 2–3 colour cans + 2 clear coat
Bumper: 2–3 colour cans + 2 clear coat
Bonnet: 3–4 colour cans + 2–3 clear coat

Preparation, primer, and clear coat are just as important as the colour itself.

Final advice

For most DIY bodywork and self-repair jobs, aerosols are the best choice, particularly when combined with professionally mixed custom colours.

They offer a balance of simplicity, control, and excellent results without specialist equipment.

If you are unsure, aerosols are the safest place to start.
