Default HOW TO: Painting C7 Engine Bay Parts

So I decided to paint my engine covers yesterday. The plan:

- paint the fuse box cover Cabon Flash Metallic
- paint the lower covers Carbon Flash Metallic
- paint the plenum Carbon Flash Metallic
- paint the fuel rail covers Cyber Grey Metallic with Carbon Flash Corvette lettering.

I planned to paint them as is, not sanding them down to make them smooth. I didn't know how good it would look, so I figured i'd do the fuse box first, assess how it looks, then if its good I could do the lower covers, then the plenum. In short, I am quite happy with how they turned out but I didnt have as much Carbon Flash as i'd hoped. So I only got the fuse box cover and the lower covers done. I ordered more paint from automotivetouchup.com which should be here by next weekend and I can finish it up.

First step, clean clean clean. If it ain't clean it ain't gonna stick too well.



I chose to use an adhesion promoter since its plastic. It worked out quite well.



Two coats base, three coats clear.



And the result..









Since I am lazy.. Lol, I am just gonna leave the plenum cover and fuel rail covers off for the next week while I wait for more paint to come.

Opinions?

Ok so I got more paint in and got to working on the rest. Pics below.

Since the "Corvette" lettering is so smooth, I sanded it down with 600 grit just enough to remove the red paint and scuff it up.



Two coats Cyber Grey Metallic on the furl rail covers, no clear yet. On the plenum, two coats CFM and four coats clear.



Ok here I did two layers of hand laid CFM with a small brush on the "Corvette" lettering, then four coats clear.



I chose to do four coats clear to try to build up the clear coat as a smooth layer since I did not smooth down the pieces first. It did smooth them out a lot. I do have a few small imperfections in the clear (small bubbles) so I may try to sand them down with like 3000 grit and re-clear 1 coat. Thoughts on that??

update:
Ok so I did what I said I was gonna try. First, the plenum was quite rough still even after four coats clear. That being said I wet sanded it down with 2000 grit and then with 3000 grit so its as smooth as can be. This pic is after wet sanding:



At this point i put on 1 "wet" coat of clear and now this thing is really smooth. Here is a pic:



For the fuel rails, I just put one more coat of clear on them to give them some extra pop. 5 total coats of clear at this point. Since they are textured and I did them in Cyber Grey, they almost have a carbon fiber look to them in person. Pic:



Going to let them dry till Saturday and then put them on the car and polish/seal them up.

Looks very nice IMO. Great paint job, relatively simple to do. Gives the engine bay an understated but much improved look.

I always wondered how long paint really holds up to engine heat on these covers?
Oh well, can't paint mine anyway since I got it autographed by the Stingray design team.

These pics don't really do it justice.. I'll get a few good ones when I charge up the good camera.

actually, your build thread was the inspiration to start painting in the first place Glen! Lol

Since my car is "murdered out" that's exactly what I am going for..

Why not at least add a clear coat? Would protect it so it lasts longer for sure!

Thanks for the pictures, they look great. I also want to paint mine when I get my car.
The Adhesion Promoter is a great idea.

Default more, moore, and moar!

I decided to take off and also do the plastic cover on the underside of the hood, as well as the radiator cowl piece. Also did the tube for the Halltech Stinger intake that just came in too. Pics below, These look pretty good to me

two coats base..




Four coats clear, then wetsand with 1000, 2000, then 3000 sponge pad.



Now I hit it with a buff pad using Mcguiars 205 Polish, then followed up with Mcguiars 7 Show Car Glaze. After 30-45 days, I will hit it with some Mcguiars 26 Yellow Wax.. but even now it looks soooo smooth..



did the same for the intake tube..



(it was cloudy outside)

very nice ...but start using a sealant, at that temp, wax won't last...if you like Meg's, use their NXT2.0....

automotivetouchup loves you!

hahaha I bet!!

Good advice on the sealant. Should I seal first, then wax? Never used sealer before. To be honest, this car was the first time I have decided to teach myself to really paint parts so I'm learning as I go along.

That looks fantastic! Had a similar desire to up the under-hood pop. Automotive Touchup paints in: Arctic White, Carbon Flash and Torch Red.

So I use that instead of the glaze? Or in the list of things I have already done it would be next in line?

Cake. Fuel rail covers pull right off, its only two bolts for each lower cover and the plenum has 4 bolts and a handful of plastic wiring holders to pull.

forget the glaze...just do a sealant after you are done polishing...wipe down with alcohol and put on two coats of NXT or Nu finish, if oyu want to buy local

If you want to order, Opti Seal and Blackfire Crystal seal are a few great ones...
