Graco sg2 vs. sg3 Performance

Before choosing any spray gun, know your needs and projects on which you’re working. Selecting the most suitable gun for your specific tasks is important.

If you work as a spray painter, Graco SG3 is an ideal and updated choice as it can easily handle heavy-duty and industrial painting projects. SG3 is preferred because it has a powerful motor, larger tip size and advanced features. It is specially designed for thicker coatings and materials; therefore, it can handle high workload projects easily.

On the other hand, if you’re a DIYer or painting is your hobby, go for SG2 as you’ll be doing only light duty and small projects including painting furniture, houses and fences etc. It enables you to achieve impeccable results without breaking the bank.

Overall, both spray guns have received excellent and similar feedback. But in comparison to other products, people find SG3 more convenient and user-friendly.

If you’ve some extra cash to spend, I suggest you buy the SG3 metal spray gun. However, if you already have the Graco SG2, don’t go for SG3 as they’ve many similarities in features, compatibility and design.
