After a quick shake to make sure the resin was mixed correctly, I began applying it using an old brush. Drying quite quickly and nearly clear, it was hard to tell which parts I had applied the masking agent to, and in the end I applied more than I had planned. After letting it dry for a few minutes I applied the top coat, and once that was touch dry I merely brushed my finger over the surface which began to peel away very easily.
I was very impressed with the speed and ease of use of the masking agent, and apart from the need to hold the model up to the light to see where you've actually applied it (being mostly transparent as above), I would thoroughly recommend using this instead of any other salt/hairspray/chipped paint method you might read about. After a little weathering and shading I had the base all done and ready for a model!
I must admit the photos in the last post were poorly washed out and over-exposed, and although I haven't gotten the focus right yet I took the opportunity to use some of the lovely summer sunshine to snap a pic of all the bases so far. I'll be picking up the models for this set from the store this week, watch this space!
