I thought you had this all figured out. Do you realize you have almost 5 pages of posts, 4 of which are entirely devoted to you? You've been at this since last February.
At this point I don't think it makes much sense for you to continue. It just is not as hard to do as all your issues would indicate. You've been all over the map with the amounts o0f water needed and that you have tried. Your co0ntiual changing up of the amounts of water has been your undoing, because you have no consistent viscosity to work out a spraying method with.
It doesn't work like that. And there just isn't that much difference between all these Guns, certainly not so much that after 11 months one cannot find a happy medium.
With S-I-L-V-E-R, or any thin paint, you start off with the least amount out water and add until you get a proper spray pattern. You misjudged the amount needed early on and added too much, and now it's become a "Gun" issue that's to blame.
If one changes over to a different Gun, then obviously one has to make adjustments. In this case, trying to equalize the needle size and pressure.
I know that if I was to pick up any one of the Guns you have had, and mix a batch of S-I-L-V-E-R, by day's end I'd be finished. And a great many before you have done likewise.
I just almost feel that I have nothing more to add here, because I cannot fathom what seems to be continually plaguing you. It just isn't that hard or difficult to make the needed adjustments....and basically, all the effort to9 do so has been more detrimental than helpful. You know how much I want to help you...I haven't spent all the hours doing so because I( didn't want you to have success.
But every once in a great while there comes a time when someone needs to realize they just don't have the knack. Or....that some kind of evil hex is upon them. Someone such as yourself, who has spent considerable...even insane amounts of time and effort, and no small amount of funds, and still cannot get past 1st base....well that simply screams "STOP !" because all your doing is frustrating yourself, and essentially making it seem that a simple DIY solution comes with intractable issues...which is not the case at all.
Now that I've vented....I'll add this.
You have not carried a single attempt out far enough to even judge what might be the end result. You've been too worried about what the initial coats look like, and not made it past that point. S-I-L-V-E-R always looks like something is amiss early on, and only the continual build-up of paint produces the eventual finish. Make the Mix as originally described, and if you find a discrepancy in the listed amounts of water to add, then go with the "lessor" amount first. Start out with a higher pressure and smaller nozzle and reduce pressure until you get a even flow. Use straining to remove any debris or clumps, forget about "flow-through" rates.
Just make a complete attempt, using some Thrifty White or similar sheet.
You know I wish I could be there to just get'ter dun for you.....I know you have the will, and the desire...and I don't ever discourage those feelings in any DIY'er.
But I think it's time after 11 months and over 100 + posts and PMs that this Thread got back to being something other than a testimonial to your personal efforts...and issues.
Your welcome to continue to PM or call, but lets give all these repeated postings a rest.
