小弟孕瞞-1滲線,但之後用棉花棒+沾少少x20黎抹出界D油漬,但會令該表面(白色底)少少black'<---is it my steps have any problem?xf'1 的濃度是否像水(稀dd)?

試下再用力d抹抹...

完全唔係力度既問題
睇你似用錯了啞白/半光澤白做底

你應該用光澤白做底
之後滲線
再最最上top做番啞色、半光澤或光澤

not use 啞白做底????

d線唔夠深又係啞色上滲線, d線會易散開的.

You can feel the surface after spraying white... (actually this can happen in any colour, I have encountered before) If it feels rough, not smooth, the black lines will spread, and you can't wipe it away cleanly, if you wipe it stronger, you'll wipe the white away as well. Make sure that you turn your pump to low level to spray, otherwise the surface will be rough after spraying and affect the black lines. Doesn't really matter whether you use number 1 white or number 62 white. If you wanna have "flat" effect, you can mix them, but no necessarily use gloss paint first, put the lines, and then spray flat paint again, will waste a lot of time. Just make sure you turn the pressure low. My Z plus is similar to your case now, and I adjust it in F91 and it works quite well. This is from T hobby's boss. His idea works nicely.

low level to spray is it mean 用細氣壓?較細d吹出黎d風??what is th6e prin

Yes, use lower pressure. Of course you need to make the paint thinner. If the pressure is too high, the paint will dry up in the air before it reaches the part, and the part will feel rough like sandpaper. Using lower pressure will keep the paint wet when it reaches the model, the part will still feel smooth.

<<<<<那些enamel油已經因為表面粗糙而化開了, 就像我們受傷擦紅藥水, 藥水從皮膚上的脈絡散開一樣!! 所以就"骯髒"了!

要用enamel滲線最好用光澤油上色, 然後滲線, 再噴消光topcoat的啦哈哈!!

how low pressure?

Around 15. Pls be reminded that I'm not trying to say that the above mentioned methods are not good. They work well as well. You can try which one suits you more. Especially if you have sprayed already, you may need to spray a gloss layer first, put the lines then spray the flat paint again, unless you wanna wipe all the paint away.
