Tamiya Extra Thin vs Mr. Cement S
Two capillary cements, one seam — is there a real difference?
Option B
Mr. Cement S
The hotter, faster flash
| Spec | Tamiya Extra Thin | Mr. Cement S |
|---|---|---|
| Mechanism | Solvent welds styrene by melting the joint | Same — slightly hotter solvent blend |
| Flash time | Slower — a few seconds of reposition grace | Faster grab, less forgiveness |
| Capillary flow | Excellent wicking along seams | Slightly thinner, races even further |
| Brush | Fine cap brush, good control | Similar fine brush |
| Availability | Everywhere Tamiya is sold | Hobby-import channels |
| Price | ~$5–8 / 40 ml | ~$6–9 / 40 ml |
The verdict
Functionally these are siblings: touch the brush to a joint, solvent races down it, squeeze, and the seam welds into one piece of plastic. Mr. Cement S flashes faster — pros like the speed; beginners appreciate Extra Thin’s extra seconds to seat parts.
Buy whichever is on the shelf; keep exactly one open at a time (they evaporate), and remember the golden rule of solvent cement: wait a full day before sanding a welded seam.
