Blap! Models/Goodman Models Super Sanding Blocks
By Matt Bittner
Blap! Models, in association with Goodman Models, has produced this unique set of sanding blocks - called Super Sanding Blocks - that will help with all aspects of modeling. You can see in the video they produced all of the advantages to using these sanding blocks. Not only will they help create flat surfaces but they can also be used, with the correct motion, to sand seams away on circular surfaces as well. The one aspect I like is how they can be set on edge to create a 90 degree surface. But remember, those surfaces are only as "straight" as you can make them. If one of the surfaces are angled, you will still have a 90 degree bend, but it will just appear "crooked" because the surface being held down is "crooked".
Be that as it may, I decided to give them a try by sanding the pour area from around the chassis of the Videoaviation.com 1/72 Coleman MB-4 Tow Tractor. There is a "wafer" of resin surrounding the chassis that needs to be sanded away. Since all but the 80 grit of these sanding blocks are water proof I sanded the wafer away using the 220 grit under running water. (In hindsight I should have started with the 80 grit to take away the majority of the wafer than switched to 220 as the sanding took me closer to the actual kit part.)
Using a circular motion during sanding eventually the wafer sanded away. You can see the leftover "film" of the wafer in the photos below which was thrown away since it is no longer needed. Using a circular motion is important so you don't sand one are more than others, resulting in a "flatter spots".
Not only can the blocks be used for this type of resin-sanding, but they can also be used for smaller vacuum-formed parts as well, again, using a circular motion while sanding. Unfortunately they're not big enough for some of the larger parts but then you would get into a much larger price-point.
For what they were designed for, Blap! Models/Goodman Models Super Sanding Blocks work very well and I can definitely recommend them. You receive six different grits (80, 180, 220, 320, 400 and 600) along with a legend card that coupled with colored dots on the blocks will help you in keeping the grits straight. As I mentioned previously all but the 80 grit can be used with water.
