Prepare mask and hair coverage before refinishing, make sure there no change for dust or hair to fall off onto surface being sprayed. Read instruction carefully and double check refinishing supplies are accurate and enough for the work. Clean spray guns thoroughly before staring to measure the liquid.
Check again that the surface of plate is well sanded and holes filled. Blow with compressed air to get rid of dust.
When spraying, move body and arms smoothly at an even speed. Make sure all corners are covered. The result is much better by spraying several thin layers than one thick coat. This the initial pass as primer. The plate will be sanded and sprayed again for a much smoother result.
