They are both used in much the same way but due to the finer granules after sanding with waterproof sand-paper, a perfectly corrected surface is possible. Available in bottle and spray. This surfacer can be applied to give a final finish to the surface more smoothly.It has the characteristic of being fine grained and it is not prone to clogging up detail in the mold. Most suitable not only for making a base before painting but also for surface finishing of an original mold before casting. 170ml. Continental USA shipping only, no expedited shipping available.
