Hi Diana,
If the resin surface is dirty, clean with Novus #1
Shake Novus #2 well. (Test on an inconspicuous area first if concerned about product performance.)
Apply Novus #2 liberally to the resin surface. Use the microfiber cloth to polish with firm circular motions or across scratches at right angles. Use more pressure over scratches if necessary.
Once all scratches are removed, apply Novus #2 uniformly over the resin casting, keeping the cloth saturated at all times. Allow to dry to a light haze.
Using a clean portion of the polishing cloth, buff the surface to a slippery glaze using firm, short strokes. This procedure is important to achieve the best results.
Using another clean section of cloth, apply Novus #1 to the surface to maintain the gloss and give it a protective coating.
You do not need to wear a mask with using this product.
