Terbold 16oz Paint Mixing Cups
Capacity: 16 ounces. This 12-pack offers printed mixing ratios on each cup for quick, on-the-fly measurement. Made from solvent-resistant plastic, they handle automotive paints, thinners, and hardeners. Best for small to mid-size projects where quick access to accurate ratios matters. A potential limitation is that the cup size may require more frequent refills on high-volume jobs.
Terbold 32oz Paint Mixing Cups
Capacity: 32 ounces. This 12-pack provides larger capacity for bulk mixing, with visible printed ratios for accurate measurements. Suitable for automotive paints and resin work that require more volume per mix. Choose this if you regularly mix multiple gallons or need to consolidate batches. Limitation: larger cups may be less portable for on-site quick repairs.
Custom Shop 32-Ounce (12 Pack)
Capacity: 32 ounces. Features multiple ratio scales (1:1, 2:1, 3:1, 4:1, 6:1, 8:1) and solvent-resistant polypropylene. Best for automotive painting and epoxy resin projects where precise ratios are critical. 12-pack offers convenient reuse or reorganization across projects. Caution: Lids are not included, which may affect long-term storage of mixed materials.
Custom Shop 32-Ounce (36 Pack) with Lids
Capacity: 32 ounces. This box contains 36 cups and 12 free lids, plus ratio scales (1:1, 2:1, 3:1, 4:1, 6:1, 8:1). Solvent-resistant to handle automotive paints and stains. Best for organized studios or shops that want ready-to-store containers between uses. Limitation: Lids are included, but not cup-specific storage solutions beyond simple lids.
TCP Global 32 oz (25) Graduated Cups
Capacity: 32 ounces. Includes 25 disposable cups with printed milliliters and mixing ratios (2:1, 3:1, 4:1). Made from solvent-resistant PET plastic. Best for mixed-material workflows and teams that need a consistent, disposable option. Better for short-term projects; not intended for long-term storage of mixed materials.
TCP Global 20 oz (50) with Mixing Sticks
Capacity: 20 ounces. This set includes 50 cups plus 50 wooden mixing sticks, with printed ratios (2:1, 3:1, 4:1). Suitable for quick, small-batch automotive paints and epoxies. Combine with sticks for easy stirring. Limitation: Sticks are disposable; consider whether you prefer reusable tools for ongoing projects.
Buying Guide
What size should I choose for automotive paints?
Choose 16 oz for small touch-ups and 32 oz for larger batches. Larger sizes reduce refills but may be bulkier to handle on the shop floor.
What should I look for in ratio markings?
Printed ratio scales (such as 1:1, 2:1, 3:1, 4:1, 6:1, 8:1) help ensure accurate measurements, reducing waste and errors in color and hardener mixing.
Are disposable cups acceptable for automotive paints?
Yes, solvent-resistant polypropylene or PET cups are designed to resist solvents used in paints and thinners. They are ideal for single-use or short-term projects, but not for long-term storage of mixed materials.
Should I get lids or storage options?
Lids are convenient for storage between steps or for organizing multiple projects. Some packs include lids, while others do not. If you need long-term storage, plan to purchase lids separately or choose a kit that includes them.
Is it better to buy in a multi-pack or mixed sizes?
Multi-packs offer value for ongoing workflows with various project sizes. If you frequently switch materials, a kit with several cup sizes and included lids or sticks can simplify setup and cleanup.
Durability and reuse considerations
Polypropylene and PET cups provide solvent resistance, but consider whether you want reusable cups that you can clean and reuse, or disposable cups to minimize cleanup time after a large project.
Quick reference: selecting by project type
- Body shop and large projects: 32 oz cups, many packs, with lids
- DIY hobbyist or small repairs: 16 oz cups, smaller packs
- Epoxy resin or multi-material projects: cups with clear ratio scales
Frequently asked questions
- What is the main purpose of paint mixing cups?

Some cups are designed for reuse; others are best treated as disposable. Check the product notes for solvent resistance and cleaning guidance. - Which cup size is best for primer applications?
32 oz cups are often preferred for primers and larger batches, but 16 oz can work for small primer touch-ups. - Do these cups come with lids?
Some kits include lids; others require separate purchase. Lids aid storage between steps. - Are there cups specifically for epoxy resin?
Yes, several options include ratio scales and solvent resistance suitable for epoxy resin mixing. - Should I use wooden sticks with the cups?
Wooden sticks are common in kits and help with consistent mixing, especially for resin or paint blends.
