Question about Spray Gun and Air Compressor

Hello brothers~

I just picked up a Mini-compressor for painting.  I need to buy the hose (air tube) and a spray gun next.  What type of air tube and spray gun should I buy to paint RC Car bodies?

Also, my air compressor doesn't have a 壓力錶, should I buy this "水隔有調壓器及壓力錶" combo?

Thanks in advance~~

要睇你個泵係咩泵先有得講喎......

細泵未必一定要買水隔,主要都係睇你果隻係儲氣式定係直出.

至於噴槍,主要都係要買噴咀比較幼細果O的啦.....太粗噴出嚟唔得幼細......
要慢慢睇.

Thanks brother AMAT,

泵係直出, 唔係儲氣式.
噴槍 0.3 ok?  Something like this:

呢只泵嘛嘛地，最好唔好直出，好易烧泵个摩打，就算买直出都要买D要有水隔，同会够压就cut电果D。枪嘴0.3粗左D，最好0.2啦，我自己用紧孖星spray-work HG（74514），几好咖，又唔算贵！

支枪边度出噶？？好似我系广州见到果D国产野，如果真系国产嘅喷枪，最好唔好买啊，好鬼流！喷枪暂时都系德国嘅好，据我所知孖星支枪都系德国厂OEM！
