Spray Gun

HVLP will save you a ton of product usage. I suggest the 3m accuspray for your project. it has interchangeable tips and sprays well.
Yes yes yes!!! I have gone through countless guns over the years and this has been the best value ever! Comes with 5 needle sized caps which are good for several sprays each and are cheap to replace. Also, it is a little bit of money but the disposable cups are so nice and they allow for spraying in all positions due to the atmospheric pressure squeezing the paint into the gun as opposed to gravity. I get my cups on amazon as aftermarket ones and they are much less money than the 3m brand.
