detailed instructions can be found on my website for stencil application
http://www.flipperescue.com/stencils.htmI havent used the stencils in question, but basic rules apply to any stencil.
First up is that the smoother your base coat, the better adhesion you will get. If its very smooth, then the edges of the stencil can seal and this leads to less bleed... this is mainly an issue if spraying whilst cabinet is upright as bleed can happen at the bottom of the cut out shapes.
A good look at any cabinet will reveal that the layer of paint is very thin... main flaw of any home stencil is that far too much paint is sprayed on... once again, this risks bleed.
When stencil is on.. spray 1 VERY light coat like a fine dusting... allow this to dry. Repeat again... this is all the paint you need to recreate the artwork.
Flat finish paints bleed much less than gloss.
Take your time with any registration you have. If it takes 2 days to redo the artwork, thats OK. No prizes for a quick job... only a good job.
Good luck....
