When finishing a Gunpla build, the final clear coat can make or break the overall look. Two popular options in the modeling community are Mr. Color C46 Gloss Clear and Mr. Hobby Top Coat. Both promise protection and a beautiful finish, but they serve different purposes and excel in different scenarios. In this comparison, we'll break down their differences in finish, durability, application, and best use cases, so you can decide which one deserves a spot in your toolbox.
Whether you're a seasoned builder or just starting, understanding these clear coats will help you achieve that professional, polished look. We'll also touch on how they interact with panel liners, decals, and weathering, because the order of operations matters. By the end, you'll know exactly when to reach for the spray can of Mr. Top Coat and when to grab the bottle of Mr. Color C46.
Understanding Mr. Color C46 Gloss Clear
Mr. Color C46 is a solvent-based gloss clear that comes in a jar and is typically applied with an airbrush. It's known for its high-gloss, glass-like finish that's perfect for creating a smooth base for decals and panel lining. The gloss surface helps decals adhere better and reduces silvering, making it a favorite among builders who want a showroom shine.
One of the key advantages of Mr. Color C46 is its durability. Once cured, it forms a hard, protective layer that can withstand handling and minor abrasions. This makes it ideal for kits that will be posed and played with, or for those that need a tough base before weathering. However, it requires more preparation and equipment—an airbrush and proper ventilation—so it's not as beginner-friendly as a spray can.
- High-gloss finish ideal for decals and panel lining
- Durable and provides excellent protection
- Requires airbrush and proper ventilation for application
Understanding Mr. Hobby Top Coat
Mr. Hobby Top Coat is a spray can clear coat that comes in three finishes: gloss, semi-gloss, and flat. It's incredibly convenient—just shake, spray, and you're done. The flat version is particularly popular for giving Gunpla a realistic, matte military look, while the gloss version offers a shiny finish similar to Mr. Color C46.
The main appeal of Mr. Top Coat is its ease of use. It's perfect for beginners or for those who don't own an airbrush. The spray can delivers a consistent coat, and it dries relatively quickly. However, it's not as durable as Mr. Color C46, and the finish can be slightly less uniform if you're not careful with the spraying distance. For most hobbyists, though, it's a reliable go-to for final protection.
- Convenient spray can, no airbrush needed
- Available in gloss, semi-gloss, and flat finishes
- Best for quick and easy final coats
Key Differences: Finish, Durability, and Application
When it comes to finish, Mr. Color C46 provides a deeper, more mirror-like gloss compared to the gloss Mr. Top Coat. If you're aiming for a 'wet look' or a candy coat effect, C46 is the better choice. On the other hand, Mr. Top Coat's flat finish is unmatched for a matte, non-reflective surface that hides imperfections.
Durability is another differentiator. Mr. Color C46 is tougher and more resistant to scratches, making it suitable for kits that will be handled frequently. Mr. Top Coat, while protective, is more susceptible to scratches and may yellow over time if exposed to sunlight. For long-term display, C46 is the safer bet.
Application methods also set them apart. Mr. Color C46 requires thinning and airbrushing, which gives you more control over the thickness and sheen. Mr. Top Coat is a simple spray, but you need to be mindful of humidity and distance to avoid a frosted or uneven finish. Both require a clean, dust-free environment for best results.
How They Work with Panel Liners and Decals
A common technique is to apply a gloss coat before panel lining and decals, then a final top coat to seal everything. In this workflow, Mr. Color C46 excels as the pre-decal gloss coat because its smooth surface allows panel liner to flow effortlessly into recessed lines. After applying decals, you can then spray a flat Mr. Top Coat to tone down the shine and protect the decals.
If you're using Mr. Top Coat gloss as the only clear coat, it can still work for panel lining, but the finish may not be as smooth, leading to slightly more resistance when the liner flows. For best results, many builders use Mr. Color C46 for the gloss phase and Mr. Top Coat for the final finish. This combination gives you the best of both worlds: a perfect base for detailing and a durable, attractive final coat.
- Use Mr. Color C46 for a smooth gloss base before panel lining
- Apply decals over the gloss, then seal with Mr. Top Coat
- Flat Mr. Top Coat tones down the gloss for a realistic finish
Which Should You Choose?
The decision ultimately comes down to your priorities and setup. If you own an airbrush and want the highest quality gloss finish with maximum durability, Mr. Color C46 is the professional choice. It's also the go-to for serious modelers who plan to weather or apply multiple layers.
If you're a beginner or prefer the convenience of a spray can, Mr. Hobby Top Coat is your best friend. It's perfect for quick projects, and the flat version is essential for giving your Gunpla that 'real robot' feel. Many builders keep both in their arsenal—using C46 for the detailed work and Top Coat for the final seal.
No matter which you choose, you'll want to pair it with quality tools. For example, a good brush like the Citadel Synthetic Base Brush X-large is handy for applying decal setting solutions, and a Citadel Water Pot is essential for cleaning your brushes. And if you're painting a new kit, consider the GUNDAM Assemble Color NGA14 Gray for a primer that works well under both clear coats.
