primer yellow?

[David_]

ok, first off, let me say i've checked the faq, and i couldn't find any info on this.

i want to spray paint a car yellow, and i heard yellow is a colour that you tend to see the undercolour thru...(weak colour)

the shell that im painting onto is also yellow... so if i were to use primer, wouldn't it do nothing but wrong? or is there such a thing as yellow primer?

please recomend me something to prime with, thanks.

You are correct - yellow, particularly Tamiya's Chrome Yellow is a weak colour. It doesn't cover as well as you would think. I personally use white primer (usually Tamiya's) under lighter colours such as yellow. It gives pretty good results.

so white primer works? i don't understand how.... if you could please explain, i'd appreciate it, (coz shell is yellow, so why not spray over shell), but if u cbf explaining, i'll take you on your word and use "white" primer... thanks ^^"

It depends what colour plastic the shell currently is. It can be difficult at times to cover a darker yellow shell with a lighter yellow paint - the col;our tends to appear to bleed through. The white primer negates this effect to a large degree. You could try it with out primer and see how it goes and then if it doesn't then strip, prime it white and do the yellow again. Hope this helps.

hmm yes it does thanks... only, will caustic soda strip the paint? tamiya colour paint?

also, where abouts in australia are you?(state, suburbs, etc)

[cyclone1410]

Try Oven Cleaner or Brake Fluid to strip the paint. I am in Brisbane (northside).

ahh thanks, and i have another question about priming, if i were spraying black, the shell was white, can i still use white primer?or does it have to be grey?

Yellow body plastic is somewhat translucent, and yellow paint is weak. So, if you don't use primer, the result will look like a cheap plastic toy, no matter how many layers of yellow you put. And more paint will kill the details. Also, you can't paint the interior in dark color, because it'd affect the exterior. That's why you use primer, even if the shell is already yellow. I use tan as the base color, when the body is going to be yellow, and it works well.

so if i use white primer, i can have a dark interior and it wont look wrong?
