Hello friend,

Having seen Ah Pongs repaired NYX pictures, I am interested in trying my hands with spray gun painting on my own repairs. ( perhaps also try that on my car too )

I've done some reading on the subject on internet. The setup should consist of a spray gun, air-compressor, air tank, water filter, etc.
Anyone have experience with such equipments ?
I expect it should be similar to those used in car repair workshops ?

I know car repair workshops have high temperture room and professional equipments, which is out of my reach. My budget is within a few thousand hkd, so I have to spend it wisely.

Someone said about using epoxy paint, is it the same as paint used on cars ?
I'm looking for nice looking paint finish, that is more resistant to dings on landings.

Please give suggestion on :
Which brand to use ?
How much do they cost ?
Where can I buy them all?

Thank you

阿麥真係越玩越發燒渦﹗買噴油架餐去新填地街同廣東道一帶睇下啦﹐一次過可以掃齊。

風泵﹕有分靜泵同嘈泵﹐靜泵就係好似雪櫃/冷氣機果亭﹐嘈泵行活塞﹐顧名思義靜泵就好靜嘈泵就好嘈﹐嘈泵一般都係較平﹐但係住宅入面用嘈泵可能會俾人投訴﹐要諗諗。買泵要留意三樣野﹕壓力﹐氣流量同氣缸容積。噴油所需壓力一般都唔係好大﹐但氣流量就要有番咁上下。否則噴兩野就要等個氣缸充氣。氣流量視乎噴槍大小。我個泵係靜泵﹐spec 係﹕壓力: 8 bar, 氣流量﹕ 32 ( 要頂 8 bar 果陣 ) – 50 ( 唔駛頂壓力果陣 ) liter / minute, 氣缸容積 : 9.5 liter. 可以參考下

噴槍﹕我用緊呢枝﹐唔記得幾多號﹐以前有枝大D既﹐但唔覺得特別好用﹐送左俾人了。

水隔﹕我有個多左係度﹐你可以囉去用。

油漆﹕一般都係用 Epoxy 或 Polyurethane (PU) 油。因為呢類油既抗磨抗腐蝕性強。我以前玩 engine 模型果陣係用開美國 K&B 俾模型用既 epoxy 油同飛魚牌既“油霸”﹐ 後者屬 PU 類﹐好平﹐光澤度極高﹐抗磨抗蝕性好好。但顏色唔多﹐未必岩你用。要顏色多睇怕都要用汽車漆油﹐好似 ICI 既 2K 系列或阿堅用開果隻﹐ 汽車油漆店有售。我以前係去銅鑼灣日昌買。不過好耐無買了。阿堅應該有好窿路。至于焗油就真係要睇邊隻油﹐我用過既 epoxy / PU 油無隻一定要焗﹐但一般我都會焗焗佢﹐所謂焗都只不過係擺件野係一間密封同氣溫保持係約 40 度既房入面。等D油快D硬同唔會受水氣影響而發白。

YC,

I've just got myself a set of paint spray equipments on Saturday.

It's the noisy compressor I've got. It's powerful, but you are right, it's impossible to use it during the night time!
I can do my paint spray outside the house, in the day time only.

I'll try to convert my vacume pump into a compressor for small repair jobs. If that doesn't work ! how much is the 靜泵 ? I might have to get one.

For the repairs of the old planes, I got some epoxy paint to match, but they are very expensive at $60 to $80 per 1/4 liter. However, the six colours I bought, took them 1.5 hours to get the mixings done.
So, they worth every penny I paid for them !

If I'm spray painting some new planes, less expensive paint will be better. How much did you paid for your "油霸" ?

I'm now building the AMD P-51D, and will glass it and do my first spray paint job on it.

Lets see how it come out :roll:

靜泵睇牌子啦﹐以前意大利果隻 Silair 大約二千幾﹐靚D既丹麥牌子 Junair 大約四千到。依家D價係點就唔知囉

我用果隻"油霸"4 公升裝大約賣 $200。一罐用兩年都用唔晒。"油霸"只係要黎做面頭果浸保護光油﹐底層都係用普通噴油﹐貪佢平﹐顏色多同快乾。正先我地係用 ICI 汽車噴漆﹐後尾發覺手掃漆都掂。手掃漆既優點就係快乾 (等一個鐘就可以落膠紙噴第隻色) ﹐好省﹐易拋光。

你用D epoxy 油如果要噴花要小心呀﹐epoxy油硬化左就百毒不侵﹐即是話你噴第浸油上去係唔會咬得實已經乾左果浸﹐用膠紙好容易就可以黐番出黎﹐一定要事前用幼砂紙加水省﹐好麻煩架﹐上面D普通噴漆就無呢個問題。

係咪即係話用普通噴油噴完,乾咗再噴油霸就攪掂?
重有,請問Minor邊度有得賣?幾錢?

係呀﹐但呢種做法會較重﹐只適宜用於強風機。

minor = mylar ? 甘兆記有售﹐地址係旺角廣東道903 號。 價錢視乎厚度﹐幾錢就唔記得﹐只記得唔貴。

再用以上方法噴油, 唔知掂唔掂, 各位師兄指教下啦, 有乜野要注意架?請多多提點提點。
