Engine Clear Coat for Aluminum? Help!!!!

[69clark]

I want to clear coat my cast aluminum parts for my engine build up to keep them looking good. however I don't want a clear coat that will yellow. Aboat 5 years ago a buddy of mine built a sweet looking 350 sbc and cleared is waterpump, heads, and intake (just like I want to do) but after we got the engine installed and running, within a week the clear coat was turning yellow. As you can image it is alot of work to fix that. If I remember right he used a good brand of clear that was made for engines but it didn't matter.

Anyways does any one know of a good clear to use on these cast aluminum parts. I don't want guesses (I want it right the first time) just known cases of what works. My other alternative is to paint them cast aluminum color, what do you guys think?

My cousin used eastwood's clear coat for bare metal and it did not turn, but I honestly can't remember what he sprayed with it. MOST clears will turn yellow unfortunately. I am going to try powdercoating some polished parts that get hot clear and see what happens with it. The clear coat does dull the luster of the polished metal though somewhat.

i'm in the same boat.

i want to polish my front accessory brackets but i dont want to be polishing it every week to keep it lookin good.

i was thinking about clearing it with paint or powder. i even thought about just getting it coated in xtreme chrome powder.

i polished my iac on my throttle body and sprayed some duplicolor hightemp engine clear over it. it turned yellow right away.

dont want that to happen again

They do have a high heat clear coat in the engine paint selection at the local parts stores. Same company that makes the engine paints.

That is what my friend used and it turn yellow instantly when he fully heated up the motor.

I did all my brackets by blasting em then using Dupli-Color hi-temp ceramic spray.....It still looks good 2 yrs later, but they did tint some...Better than looking at oxidized Alum for sure...
If I had it to do over I would def powder coat....

the engine bay is going to go through alot of changes this spring. more polishing and some chrome for a change, wire hiding, welding, painting, and some engine performance related goodie LOL

i'll get some of those braided line rad hose maybe....

whats turbo hoses????

 

[RIO5.0]

there made out of silicone and much "thinner" than fernco fittings...they cost a few bucks more though...type in turbo hoses in your search engine...lots of people make em..

 

[Dan95-5.0]

ah yes, i thought you were talking about my upper rad hose

i did a search and those connectors came up then i got confused hahaha

these cheap ass ferncos will be ok till later on when i'll "need them" LOL
