Not bad. The model glue on the orange cover will slightly dissolve the model surface, and the solubility is lighter than that on the white cover. After the bonding part of the model is clamped, it usually takes 5 to 10 seconds to bond. Depending on the amount of glue, it is completely dry in less than an hour. I used a green cover, which dissolved less than the orange cover and only penetrated into the joints of the connection points, so it was called slip joint glue. These three kinds of plastic white covers are suitable for large areas and plain groups, because they can make the joints dissolve inconspicuously and can hardly be seen after grinding. The green cover is suitable for precision parts and places that do not need grinding. After use, the gap needs to be filled with soil to repair the joint. The advantage is that the plate will not change much. The orange cover is located in the middle, but the white cover is more mobile than the green cover.
