Lexan paint help, paint won't stick

[MrTross]

I bought some tamiya paint and cleaned my shell with warm water and a bit of dish washer liquid and painted it! But the paint keeps flaking of any help or advice on best way to get pain to stick or a alternative paint to use would be great*

Firstly I'd chek that it says suitable for polycarbonate on it, I belive there are some tamiya paints that are for a different purpose and dont work.

Given that its right, if your spraying a single colour just get a brasso or something that will lightly scratch up the inside of the body (Dont do the window areas)

Give another good wash with hot water and washing up liquid and give a good rinse. (sounds like youve done this step fine already but...)

then when spraying do light coats, light coat the body then dry with hair dryer/heat gun then apply next coat, follow that method until you have the required coverage so you cant see through the body when its sat on the floor.

Hope that helps.

Also Tamiya paint is the best in my opinion (nothing better out of a can)

There are TS-xxx and PS-xxx paints. The PS paints are designed for lexan/polycarbonate.

Haven't used either myself but I did some research before deciding to buy an airbrush.

The paint is tamiya PS and ses for polycarbonate, other people at my local club have had similar problems with Tamiya paint :S

When u say brasso do u mean the metal polish?*

My appoligies I meant the brass scouring pads, I think they come in brass copper and other variants, anything to lightly rough the surface of the body for the paint to stick too.

Something like that will do, I think scotch brite make various one available for about £1 at wilkos or asda.

Havent used tamiya for a while as I airbrush but it used to work fine, I think its more likely to be how thick your laying the stuff on. Smooth strokes and even coats

If it's coming off I'd get off what you can and then buy some new paint. They haven't imported it into the country for at least 5 years so maybe it's just old stock.

You did shake and stir it real well didn't you ? It shouldn't pull off, best paint I've ever used !

Get some Createx or Autoair paints, they're essentially what 90% of us on here use.

If it's proper Tamiya PS paint, I suspect it's been applied in too heavy coats, especially if it's been prepped properly first.

A couple of tips:

as has been said- first rule- thin coats. First coat just a dusting. Second coat a bit thicker but only just thicker than a dusting. allow to dry in between coats and expect 4-5 thin coats to get enough paint on. Enough paint means you put it on the floor, or hold away from a light and it looks like a solid colour. If you hold the shell up to the light you will see light through it, that's fine and normal.

Spray in a warm room. Do NOT a cold shell with paint from a cold can, in a cold room (or shed).

Hope that helps.
