Your first job is to control the inventory. Write everything down and have stock levels for everything. Take control of purchasing. Not too much, not too little so you run out. This is a fine line.
Then control quality at every step of the way. Start with, of course, the inventory. Then what happens to the inventory one step out of storage, ie., you say the coatings, take control of that. Make sure you're not doing too much and throwing away a lot, or doing too little and having to rush it (quality suffers). Etc. etc.
Give yourself some time to be creative. The first two things will go a long way.
