I picked up a small "air brush" by Badger this afternoon at a local craft store call Richards. It has a little glass bulb to hold the paint and with an adapter, hooked right up to my air compressor. Three drinking straws full of Variprime plus three straws full of activator was all I needed in the little air brush to very nicely prime the two pieces of replacement hinge. Clean up was easy and fast. Great for those "one-off" priming jobs.
