Tamiya Extra Thin Cement Quick-Setting is for pre-fitted parts and tight seams where speed matters more than adjustment time. Fit the pieces first, then touch the cap brush to the gap so the highly liquid cement flows through the join. Tamiya states that it sets in under 10 seconds, around four times faster than its standard Extra Thin Cement, which means the alignment must already be correct. The fast flow-in action also reduces squeeze-out at the seam, but it is not intended for larger gaps or for elastomer parts. Fit and align the parts before introducing the cement into the seam with the cap brush. It typically sets in under 10 seconds, around four times faster than standard Tamiya Extra Thin Cement. The rapid setting time leaves no practical opportunity to reposition the parts after application. Tamiya recommends standard Extra Thin Cement 87038 instead where larger gaps or seams need attention. Do not use it on elastomer parts such as flexible tank tracks, as Tamiya warns that it can make them brittle. This is a flammable solvent cement; work in a well-ventilated area and close the cap securely after use.
