painting intercoolers
#6
I think this has been discussed before, and the opinion was that the thinnest paint possible is the idea, to stop it preventing heat dissipation, hence is Hammerite the right choice????

just gave it a quick wipe down with a dry cloth.no primer and then a couple of light coats.i have been spraying all my alloy tanks etc with the same stuff and they are coming up very good

so if you paint an intercooler black for example,black atracts heat as white reflects heat,ok?
So why do people paint their intercooler black when it would absorb the sunlight/heat when in actual fact if the cooler was painted white/silver/brighter colour (god forbid) it would reflect the heat.
Albeit this would have more effect if the car was at stand still rather than moving.
Also if the paint was thick then yes this would insulate rather than disipate heat, so why for example brush on instead of spray on ?
anyone like to add to this ?

i dont know about everybody else but im not worried about heat problems as i have got my turbo over the gearbox away from the cooler and rad and everything is heatwrapped so im hoping i shouldnt see any problem that may rise otherwise.tho i personally dont think a thin coatin of paint would hurt anyway.god knows as im no expert and may be completly wrong.will find out if it goes tits up

If you dont key up and etch prime ally before you spray paint on it will flake off, may take a while but still, it'll start to flake in time!!
The hammerite type may last alot longer if its the same as the brush on stuff as that you just brush onto bare metal without primer!

hammerite is also reflecive, so it will do a good job of stopping the cooler working efficiently imo,
coolers need to get rid of heat into the air, not keep warm lol
im sure i read an article on this somewhere, and matt black was proven in tests to work best

if you look at most they are brushed alloy, not polished for this very reason
reflective material does not transfer heat very well, hence its commonly reflective materials used for insulation, and you dont want to insulate your intercooler lol

ANODIZING PEOPLE
its not that expensive and im sure you can find somewhere local to do it in the yellowpages
that way the cooler isnt being coverd by a layer or paint its just the metal that is being colourd, its also a more durable finish and wont affect cooling etc

You should really try and find someone that can apply a thermal dispersant like TLTD, gives you the colour you want and will protect the aluminium from oxidizing which will overtime reduce the intercoolers efficiency.

I can get anodising done (amounts within reason) free of charge

In theory its like saying driving a car with a black bonnet would make your engine bay temps higher because it will be absorbing the heat which in turn would affect the temps more
I dont know why anyone would paint something thick, we gave ours a very fine mist of spray which covered it well, went on track for the day and had no issues with temp being any higher than usual.

quick go over with some red scotch, light layer of etch primer, few dustings with satin black, job jobbed
i asked the twins about the method to use to do this, and this was the answer i got. havent tried it out on the road obviously, but the results look good for minimal paint required. i find the hammerite products lay down in quite heavy coatings, but the only upside is the lack of a primer needed, so can see the advantages of that

There is some crap being talked on this thread. You dont need an etch primer or any kind of primer, as it wont be taking any kind of abuse.
And black painted surfaces dont just attract heat, they also radiate heat. And its been prven that a black painted surfaces radiates almost 8 times as much heat as a shiney alloy surface.
Black is the best colour for rads and intercoolers, matt would be best but any will do.
And you should paint all your house radiators black too

trying to apply a satin black paint that cant have a lacquer coat wud b naive not to use a dusting of etch primer to help it key
i for 1 wud call high speed stones and the like 'abuse', so id etch it just for the sake of not havin to remove it and redo it

If you get high speed stones hitting your intercooler and radiator, then you;re gonna have more to worry about than paint flaking
#33
if u mean large objects such as bricks then maybe, but stone chipping occurs on bonnets and the like with ease enough, im talkin about similar sized things like that, u kno, gravel and pebbles?
least with a primer coat, 1 stone chip wnt result in the start of a mass paint flaking situation

#35
if u mean because it doesnt require a primer coat, then fair enough, but the extra cost of the VHT paint would make it cost about the same as using a dusting of etch i guess

I've just got some of this stuff lying around
http://www.choiceful.com/choiceful-i...sol-400ml.html
but trying to think of how it works and if that would affect the 'cooler in an adverse way.
Just as people are saying matt would be preferable to satin. Or I could get a satin Hammerite spray can. Whichever would be best.
Or something else and a primer...

i'd like to add that a cooler works in a way most people don't seem to understand, its not just the outside area that works as a cooling area but the whole thing! warm air that passes through the cooler heating up the pipes it goes through then transfers onto the fins. these on mine anyway seem to go all the way through the cooler from the front all the way to the back!!! so can someone who thinks that painting the front part of it a bad idea tell the rest of us that have painted the front matt black say why its a bad idea? oh yeah and while where on the subject if any one who hasn't painted the front of there's due to knowing it has an efect on cooling, has your intercooler got a proper intercooler core or a radiator core???
#39
sensible idea! i'm sure if you asked karl about the cooling issue's he'd know something about it i'm sure. bound to have come across it at some stage!
