Nr_RaVeN said:yea I was going back and forth about that too.
I was trying to get the oxidized white paint look and having it running on the black and getting trapped in the groove. Its seen alot on white AC skins.
Were the white runs on the dark color and leaves a stain.
My heretical view

...
I like how the panel line saws into the nose tulip pattern, which IMHO is quite realistic. After all, those lines are joints between removeable panels, which often didn't fit that well on 109s, especially late in the war. OTOH, I think where the line crosses the double chevron is perhaps too obvious, because that was a line between 2 fixed panels that were never intended to be separated.
Normally, where fixed panels meet, there's only a tiny gap between them, which is filled with sealant to be essentially flush with the surrounding skin, and this sealant is then painted over. Hence, lines of this sort are usually very hard to see. In any case, because of the sealant, there wasn't usually any sort of channel for hastily applied paint to run down and streak like you're talking about above.
By "wasn't usually", I mean that the sealant was (and is) a universal standard feature in all countries both to enhance aerodynamics and to protect the plane from corrosion. The only real exceptions to its use were early- to mid-war Russian planes, where relocated and very new factory managers often skimped on the sealant against orders, in the interests of making production quotas, and eventually found themselves up against a wall for it. Also, the odd very late-war German plane sometimes lacked the sealant due to either shortages, haste, or both. But except for this, the safe money is on assuming it was there. But this is a relatively late-war German, so going without the sealant might be OK. Still looks kinda strange IMHO, however.
That said, this is also a Messerschmitt product, the fuselages of which were unusual. The reason for the narrow, vertical bands of skin panels was that the skin formed part of the internal structure. Instead of having separate frames or bulkheads down the fuselage interior as on most other planes, the edges of every other skin panel were joggled to the inside twice. The 1st joggle was small and created a shelf to which the edges of the adjacent panels were riveted, so as to be flush with the unjoggled part of the panel. The 2nd joggle was bigger and bent the actual edge of panel well into the fuselage interior, forming a transverse stiffening ring. This is why, instead of having a row of rivets along each side of the vertical panel lines, the pattern is line, rivet row, rivet row, line, line, rivet row, rivet row, line, repeat.
Joggles such as this always result in wider gaps than the standard butt joint between the edges of 2 adjacent skin panels resting atop the flange of some internal structural member. Thus, even with sealant, the vertical panel lines on rear fuselages of almost all Messerschmitt planes (including 109s) were somewhat more visible than the fixed panel lines elsewhere on the same plane (such as on the wing). So if you're assuming a lack of sealant, having the panel lines really saw across the chevrons as in the pic is OK. I'd change the color, though, at least in part. I just can't see the paint being so thin as to run down the full width of the chevron. Maybe just a few inches down from the top at most. OTOH, if the chevrons got painted over the white, then there'd be no run effect at all.
as for the rivets well no mater what I do someone will Quack just like you say
im just trying my 10000000 rivet experiment 
Most late-war German planes had much more prominent flush rivets than earlier Germans or anybody else. Although I've never seen this in writing, from looking at photos it appears that towards the end of the war, the Germans switched from countersinking the holes for flush rivets to dimpling them. This is a much faster but also much sloppier method, causing actual skin deformation for a noticeable distance around the rivet head, which itself doesn't sit quite flush within this deformed area. Thus, late-war Germans are one of the few instances in which I add shading to regular rivets. So I'm cool with how your rivets look on this plane.
