I see you are motivated.
But as I already explained in yer M4-retex... this doesn't look realistic. ^^
It doesn't look like spray paint, it's no hydrocoating... just simple overlay.
The Net is full of real-example pics.
Here an example how it could be done, incl. templates and result. Pw for pics: mm / mm .
At least you could cut out the parts of the rifle, which would not be camouflaged! It's not difficult.
Why don't you try to improve your technique?
Are you going to overflow this 1.6-categories all with
same average-style retex? Is it all about quantity/points? Come on...^^
