Micro Sol completely softens the decal allowing it to drape down onto the surface of the model and conform perfectly to surface irregularities without distortion. Micro Set prepares the surface first to enhance the adhesive properties which leads to the most amazing results in seemingly impossible places where the decal becomes part of the painted surface.
While the results are exceptional the application process requires patience as the solution needs time to work fully on the decal material. Some users note that applying too much can lead to pooling which must be wiped carefully to avoid damage to surrounding paintwork.
This package is ideal for serious hobbyists who need reliable performance on complex models with tight curves and panel lines. Whether you are working on cars or aircraft or military models this solution ensures decals lay flat and look printed on.
Superior Conformity
The formula allows decals to mold into rivets and grooves without breaking or wrinkling.
Versatile Use
Can also act as a gentle remover for repositioning decals without damage.

Microscale BMF129 Micro Set
One fluid ounce
Setting solution
Prepares surface
Enhances adhesive
The Microscale BMF129 Micro Set is a dedicated solution designed to prepare the surface and enhance adhesive properties before decal placement. It boasts an excellent user rating due to its reliability in ensuring decals stick firmly to the model surface without lifting over time.
Pros
- High user rating
- Prepares surface well
- Enhances adhesive properties

- Trusted brand
Cons

- Does not soften decal

This product acts primarily as a pre-treatment that primes the painted surface for better decal grip. It does not soften the decal itself but ensures that once applied the adhesive bonds securely to the paint which is crucial for long-term durability on detailed models.
Since this item is sold as a single solution without a softening partner modelers may need to buy a separate Micro Sol product for curves. This can increase the total cost slightly compared to a combo kit but allows for precise control over the softening process.
It is best suited for modelers who already have a softener and only need a strong adhesive enhancer for flat surfaces. If you are working on simple designs or flat panels this solution provides the stability needed for a clean application.
Strong Bond
Ensures decals do not peel off during handling or transport.
Simple Step
Adds one easy step to your workflow for better retention.

Buying Guide – How to Choose the Best Decal Setting Solution for Models
Selecting the right solution requires considering your model type, surface complexity, and budget constraints.
Model Type
Choose a solution that is compatible with your specific model material such as plastic or metal. Some brands like Mr. Hobby are designed for specific model lines like Gundam.
Always check compatibility with your paint type to avoid damage.
Surface Complexity
Curved surfaces and deep panel lines require a stronger softening formula to conform without bubbles. Look for products that mention drape or conformity.
Standard flat decals may only need basic adhesion enhancement.
Bundle vs. Single
Bundles often include both setting and softening solutions which simplifies the workflow. This can be more cost-effective than buying separately.
Solo products allow targeted use if you only need adhesion or softening.
Volume Size
Consider how many models you will build in a session. Larger bottles offer better value for frequent modelers while smaller bottles suffice for occasional use.
Small sizes are ideal for testing new brands or for travel.
Removal Feature
Some kits include a gentle remover to fix mistakes without damaging the base paint. This is valuable for beginners who may need to adjust positions.
Removers should be tested on a small area first to ensure safety.
Brand Reputation
Established brands like Microscale and Testors have decades of user feedback and proven performance. They tend to offer consistent results across batches.
Newer brands may offer unique features but carry higher risk.
Application Tools
Some bundles include brushes or swabs for precise application. These tools can save money and ensure clean lines during use.
If using your own tools ensure they are clean and soft.
Safety and Fumes
Check if the solution is non-toxic and non-flammable especially if working in enclosed spaces. Acrylic resins are often safer than solvent-based options.
Ventilation is recommended even with safer formulas.
How to Use and Care for Your Decal Setting Solution for Models
First apply a thin layer of setting solution to the model surface where the decal will go. This prepares the surface for better adhesion and allows the decal to slide into position easily.
Once the decal is positioned gently roll it with a cotton swab to remove air bubbles and excess moisture. Apply a second layer of softener on top to help it conform to curves and panel lines.
Allow the solution to dry completely before applying any varnish or protective coat to ensure the finish is smooth. Store bottles tightly sealed to prevent evaporation and keep them away from direct sunlight.
Frequently Asked Questions
How do I apply decal setting solution correctly?
Apply a base coat of solution to the model surface before sliding the decal into place. Once positioned use a soft brush or swab to smooth out air bubbles and excess moisture carefully. Add another coat on top if the decal needs more softening to conform to curves.
Can I use setting solution on all model paints?
Most solutions are safe for fully cured acrylic and enamel paints but always check compatibility first. Test on a scrap piece to ensure it does not dissolve or damage your paint job.
What if my decal silvering appears?
Silvering happens when air gets trapped under the decal. Apply more setting solution and smooth it out carefully with a swab to force the air out and ensure a tight seal.
How long does it take to work?
Most solutions work within minutes but complex curves may take longer to soften fully. Allow the decal to sit for ten to twenty minutes before smoothing and drying.
Is setting solution safe for plastic models?
High-quality solutions are formulated to be safe for plastic models and will not melt the plastic parts. Always check product descriptions to ensure they are safe for your specific model material.
Can I use setting solution on old decals?
Yes some setting solutions like Micro Sol can soften older or brittle decals to improve their fit. This can help restore adhesion and prevent lifting over time on aged models.
Do I need both setter and softer?
Using both provides the best results as the setter helps adhesion and the softer helps conformity. If you need to choose one start with the softer for complex surfaces.
