What's a fair price? ~ best coating?

I'm looking to have my new alum. intake and 2.5" hardpipes protected against the elements.

 

Options:

 

Chromed: looks to be about $800 for that....rediculous $$

 

Powdercoated: ???? (you guys tell me what's a fair price)

 

Polished: would look great, but would it be protected from rust on the pipes, or corrosion on the intake? --Could I get em all polished then clearcoated?

 

 

Best bet for the $$ in your opinion??

Powdercoat is (depending on region) about $60 for an intake and problaby $30 per pipe. This is for a good shop and assuming they need to be cleaned and blasted. You can get it done for less, but you will get what you pay for. If you have an air compresor and an old used oven (you can find them for free all the time) you can powdercoat it yoruself. A DIY setup is about $200, powder is cheap and goes a long way. Powder is 3-5 times harder than paint and thus better.

 

Chorme can corrode if it's not put on real thick, and most places put it on thin to save $$. If you are in an area where everything rusts/corrodes easily, it will be a factor. I'm not far from Portland, we have a lot of specalized industry here and crome is way cheaper than some places. You could probalby sent it out and have it done for less. It's more easily scracthed than powercat, but nothing shines like crome. Lots of "chap places" do "cheap chrome" so it's deffinatly "buyer-beware".

 

cermaic is similar to powercoat in it's surface durrability, but it's more stable at very high temps and typicaly goes on thicker. Not really nessesary on an intake/Pipe setup, but will probalby last longer (becase it's thicker). It also costs more and has fewer color choices.

 

given the cost of what you have, it's somethign you want to get right the first time. These finnishes are all nerly impossible to remove if you want to do anything different to the intake. Thsee finnishes are also very difficult to repair if it gets damaged.

I'm half wondering if it wouldn't be easier to just polish these up nice & shiny and find something to clearcoat them??

 

I did this with my *DM hardpipes and the clearcoat lasted about 2 years before it started to see a few oxidizing spots throughout by way of chips and tiny pits in the clearcoat. This included full year round driving however.

 

I could just paint a few coats on the hardpipes that will be under the front panel since they won't be seen. Of course that won't be as durable, but it's a weekend warrior now and shouldn't see much moisture and no salt in FL.

I would probably polish the intake and PC the pipes.

 

I have aluminum pipes on mine car that were polished and they still look great 3 years later. I just put a dab of Mothers polish on them and do a quick rub down after every car wash. It takes all of 5 min and they shine like chrome. No corrosion issues what so ever.

 

I also had some parts powder coated recently and it really is worth the extra $ over paint. You can't go wrong either way.

Annodizing will cause the welds to appear blackish, regardless of color selected. I use 4043 filler, it's the most stable (strongest) of the AU fillers, but the added silicon content reacts with annodizing, this is a close relitive to a forged piston alloy.

 

It would be fine to annodize if I used marine grade 5353, but that isn't as strong and I don't use it. It'd not weak, just less strong than 4043. Even 5353 will appear slightly different, it's a chemical reaction afterall. The base metal of the intake is 6061.

 

This is info I have read, I've not personaly done an annodized piece.
