< Is it easy to use? >

Yes, very easy, but follow all the instructions and procedures exactly as stated in the datasheet.

< What method of application do you use? >

You must use dip coating.

< Shelf life? >

It is stated as six months, but however it last longer in cool places.

< Things to look out for? >

Be prepared to work as in industry PCB making. No hobby procedures allowed. Always do Stouffer test, measure and mix exactly the right quantities of Calcium Carbonate and Sodium Hydroxide. Work with safety UV light, etc. Use the correct temperatures, etc.

< Is it as good as it sounds? >

Yes, I prefer dry films but this product is very good.

< I have an old Blue M oven from when I had a business, so it looks like I have a start on it. I was at first thinking of going with spin coating then decided that it would be easier to make a dip system >

The viscosity is designed for dip coating inmersion. I think that you cannot coat properly with spin coating. You should make a dip system, with a container very slim, or you may need galons of liquid. Also, the dip system must be tuned to get the right micron coating in your PCB. The speed of getting out the PCB must be controlled and be made variable in time. If you design and make your dip coating setup, email me to explain details of how to do that.
