This area of the rock shows the correct way that the filler should look after sanding. Note how the edges "Feather" into the surrounding plastic.

Be careful not to sand too much or you could dig out the putty. This concludes the work on the rocks.

You now have two pieces for your base : the rock cropping and the large rock, which is now one piece.

Do not glue them together at this point. We will paint the large rock and rock cropping first. This gives the paint a better chance to reach the back side of these rocks than if we painted them as one large piece.

Your rock base pieces are now ready for paint prepping!
