So far Im impressed with Sparmax I have 2 pistol brushes 3.5 and this one 7.0. I was using the .5 Neo TRN2 which I loved until problems . Good news is the bottom feed attachment from the TRN2 works on the side feed Sparmax brushes. I have used the 3.5 for several hours and I like it a lot. I used this .7 yesterday for a few hours just doing backgrounds on panels. But owning many brushes the mettle is after a few deep cleanings. My Iwatas I use as the bar I have 7 year old eclipses that are working better then the day I bought them. On the other hand second cleaning on a Master brush seems to be about the time it become unusable. I suspect I will a least get the 2 years of use the warranty says I will. So Im optimistic about Sparmax brushes I like being able to exchange cups and bottom feed easy to clean but you use more paint then gravity feed. I like Createx pearl paint and anyone that has worked a lot with this paint know is it is hard to work with. This sprays easily straight from the bottle not thinned and dries not blotchy at all no matter what angle you look at it from. I was using the ps290 with the fan cap and without the fan cap it sprayed fine but dried a little blotchy. The .7 just does a better job then .5 with thicker paints. I hope this brush last the two years because now it is essential.
