ASE B2 Painting & Refinishing study plan

Define each surface-preparation term (substrate identification, featheredging, sanding scratches, adhesion promotion) in your own words

List the grit sequence used to featheredge a repaired panel and explain why each step follows the last

Identify the prep steps that must precede priming versus those that must precede topcoat

Explain how surface contamination (wax, silicone, oil) affects adhesion and how each is removed

Distinguish the prep requirements for steel, aluminum, plastic, and e-coat substrates

Describe how to prep flexible plastic parts so the coating flexes without cracking

Outline the steps to prep a blend panel so the transition is invisible after topcoat

Explain the consequences of skipping a prep step on adhesion, corrosion, and finish quality

Explain how mixing ratio, pot life, and induction time interact for a given product

Describe the effect of reducer choice and temperature on viscosity and flow-out

Identify the three dimensions of color (hue, value, chroma) and how each is adjusted

Explain why spray-out cards are used to verify a color match before painting the vehicle

Calculate the correct amount of each component for a given mix volume

Describe how to tint a color that is slightly off and how to verify the correction

Sequence the steps of a refinish job from prep through final buffing

Explain how flash time, recoat window, and film build affect the outcome of a multi-stage application

Describe how to set up a blend within a panel and across adjacent panels

Explain how to apply a clearcoat so film build is even and the texture matches the surrounding finish

Identify the causes of runs, sags, and mottling during application and how to prevent each

Explain how to apply a spot repair and when a panel repair is the better choice

Identify the major spray gun components and the function of each

Explain how fluid tip size, air pressure, and fluid adjustment affect atomization and pattern shape

Describe a routine cleaning and lubrication procedure for a spray gun

Diagnose common gun faults (spitting, uneven pattern, pulsation) and state the likely cause of each

Explain how airflow, temperature, and humidity inside a booth affect finish quality

Describe the filter types in a booth and how to tell when each needs replacement

Outline a daily booth inspection routine covering airflow, cleanliness, and lighting

Explain how booth conditions influence flash time and defect formation

Classify common defects (orange peel, solvent pop, runs, blistering, fish eyes, dieback) by their causes

Match each defect to a corrective action and a preventive change in process

Review the full refinish workflow and identify where each defect most likely originates

Explain how surface prep, mixing, gun setup, and booth conditions each contribute to defects
