1Before any sanding begins on a contaminated panel, what is the correct first step in surface preparation?
A.Wash and then use a wax and grease remover
B.Apply self-etching primer directly
C.Scuff the clearcoat with 400-grit paper
D.Mask the adjacent panels
Explanation: Contaminants such as wax, silicone, and grease must be removed before sanding, otherwise sanding drives them into scratches and causes adhesion failure or fisheye. The correct sequence is wash the panel, then apply a solvent-based wax and grease remover, wiping wet then dry.
2Which sanding grit range is generally appropriate for featheredging chipped paint edges before priming?
A.80-grit only
B.180 to 320 grit
C.600 to 800 grit
D.1500 to 2000 grit
Explanation: Featheredging tapers the paint layers so the repair blends smoothly; a grit in the roughly 180 to 320 range cuts the edge efficiently while leaving a scratch shallow enough for primer-surfacer to fill. Too coarse leaves deep scratches; too fine cuts too slowly.
3A self-etching primer on bare steel mainly serves to do what?
A.Add film build for blocking
B.Act as a guide coat
C.Chemically promote adhesion and provide corrosion resistance on bare metal
D.Provide the final color coat
Explanation: Self-etching primer contains an acid (often phosphoric) that lightly etches bare metal, improving adhesion and providing corrosion protection. It is a thin coating not intended for heavy film build or blocking.
4Technician A says primer-surfacer is mainly used to fill minor sand scratches and small imperfections and is then block sanded. Technician B says primer-surfacer needs no sanding before basecoat. Who is correct?
A.Technician A only
B.Technician B only
C.Both A and B
D.Neither A nor B
Explanation: Primer-surfacer has high solids to fill sand scratches and small imperfections and is designed to be block sanded smooth and level before topcoating. It must be sanded before basecoat to achieve a level, properly profiled surface.
5When preparing bare aluminum for refinishing, why is a dedicated metal conditioner or etch step important?
A.Aluminum requires only water rinsing
B.Aluminum cannot be primed
C.Aluminum needs no special treatment
D.Aluminum forms an oxide layer quickly that hurts adhesion if not treated
Explanation: Aluminum rapidly forms an oxide film that interferes with primer adhesion. A dedicated aluminum conditioner or self-etching primer removes or neutralizes the oxide and promotes a durable bond.
6What is the main reason to apply a guide coat before block sanding primer?
A.To highlight low and high spots so sanding is even
B.To add color to the panel
C.To increase film thickness
D.To speed up flash time
Explanation: A guide coat is a light contrasting dust or spray applied over primer. As the panel is block sanded, remaining guide coat reveals low spots while sanded areas show high spots, ensuring a flat, level surface.
7Which grit is typically recommended for final sanding of primer-surfacer before applying a basecoat?
A.2000 grit
B.400 to 600 grit
C.180 grit
D.80 grit
Explanation: Primer-surfacer is usually finish sanded around 400 to 600 grit so the scratch is fine enough to be covered by basecoat yet still provides enough tooth for adhesion. Manufacturers' recommendations should always be followed.
8Why should bare metal not be left exposed overnight before priming?
A.It will become too smooth
B.It improves adhesion
C.Flash rust and oxidation can form, causing adhesion and corrosion problems
D.Paint will not match
Explanation: Exposed bare steel begins to oxidize and can develop flash rust within hours, especially in humid conditions. Priming promptly prevents corrosion under the new finish and protects adhesion.
9What is the correct technique when using a solvent-based wax and grease remover?
A.Spray on and let it dry completely on its own
B.Apply only after primer
C.Sand it into the surface
D.Apply with one rag and wipe dry with a clean second rag before it evaporates
Explanation: Wax and grease remover should be applied with one clean cloth and wiped off with a second clean cloth before it flashes off. If it is allowed to dry on the surface, it simply redeposits the dissolved contaminants.
10When scuff sanding an existing factory clearcoat for an adhesion (panel) repair, what is the goal?
A.Create a uniform fine scratch profile for topcoat adhesion without sanding through
B.Polish the surface to a high gloss
C.Remove all the clearcoat to bare metal
D.Leave the surface untouched
Explanation: Scuff sanding a sound factory finish creates a uniform fine mechanical tooth so the new basecoat or sealer can bond, while leaving the existing film intact to protect the substrate. Sanding through to color or metal is unnecessary and risky.

About the ASE B2 Painting & Refinishing Exam

The ASE B2 Painting & Refinishing certification exam verifies a collision refinish technician's knowledge across surface preparation (27%), spray gun operation and related equipment (11%), paint mixing/matching/applying (27%), solving paint application problems (15%), finish defects/causes/cures (11%), and safety precautions (9%). It is part of the ASE Collision Repair & Refinish series and measures the practical refinish skills used to restore a factory-quality paint finish.

ASE B2 Painting & Refinishing Study Tips from Top Performers

1Learn substrate identification and the correct prep for each: bare steel, aluminum, galvanized, factory e-coat, and plastic all require different cleaning, sanding, and primer choices.
2Memorize common sanding grit ranges by stage (rough body work, featheredging, primer-surfacer, pre-basecoat scuff) and why finer grit is used as you approach the topcoat.
3Practice spray gun setup logic: how fluid-tip size, fan width, fluid control, and inlet air pressure interact, and the difference between HVLP and RP transfer efficiency.
4Build a defect troubleshooting table linking each defect (fisheye, runs, orange peel, solvent pop, dieback, mottling) to its primary cause and the correct cure or prevention.
5Drill color matching concepts including spray-out panels, variant/alternate-color decks, tinting toward a hue, metamerism, and why color must be checked under multiple light sources.
6Know refinish safety cold: supplied-air respirators for isocyanate clearcoats, VOC and SDS requirements, flammable storage, grounding, and correct spray booth airflow.

Frequently Asked Questions

How many questions are on the ASE B2 exam?

The official ASE B2 Painting & Refinishing test has 65 multiple-choice questions, of which 55 are scored and 10 are unscored research questions used to validate future items. You have 90 minutes to complete the test. This free practice bank provides 100 selected-response questions distributed across the six official ASE content areas.

What is the passing score for ASE B2?

ASE uses a criterion-referenced passing standard set by subject-matter experts rather than a fixed published percentage or a curve. Your result is reported as pass or fail against that standard, so focus on mastering every content area rather than chasing a specific number.

What topics are covered on the ASE B2?

ASE B2 covers six areas: Surface Preparation (27%), Spray Gun Operation and Related Equipment (11%), Paint Mixing, Matching, and Applying (27%), Solving Paint Application Problems (15%), Finish Defects, Causes, and Cures (11%), and Safety Precautions (9%). Surface Preparation and Paint Mixing/Matching/Applying together make up more than half of the exam.

How hard is the ASE B2 exam?

ASE B2 is considered moderately difficult. It rewards technicians who can combine product knowledge (substrates, primers, reducers, hardeners) with hands-on skill in spray technique, blending, and color matching. Many questions are scenario-based, including Technician A versus Technician B items that test diagnostic reasoning.

Do I need work experience for ASE B2 certification?

Yes. ASE requires 2 years of relevant hands-on work experience for certification, and up to 1 year may be substituted with approved formal training. You can take the test before meeting the requirement, but the certification is only awarded once both the passing score and approved work experience are on file.

How long is ASE B2 certification valid?

ASE certifications, including B2, are valid for 5 years. To stay certified you must pass a recertification test before the expiration date. Recertification versions may offer different delivery options than the initial test, so confirm the current format when you register.
