C63 diffuser on w203
To be honest tudu, I'm a bit nervous about using the black sealant, when you mentioned in your thread to make sure I have a bunch of turpentine and mineral spirits. But maybe you (and anyone else that used the sealant) can help me out with some concerns I have using the sealant. Ideally, I think the sealent would work out the best, but again, I don't want to slop the stuff, get it all over my bumper, and make a total mess out of it, while still not achieving my goal of it matching the bumper cutout perfectly.
Here's my concerns:
Now that I have the black tape and adhesive promoter is coming soon, I'll probably use both the tape and the sealant. Since the tape is black, I was thinking about putting it on the leading edges of the diffuser, and then using the sealant along the inside of the diffuser. Suggestions? Should I do it this way, or install the tape more towards the inside of the diffuser and use the sealant along the outer edges. Basically, I want the top edge of the diffuser to match up exactly and tightly with the cutout line along the bumper. Right now, the diffuser is on and matches the cut line nicely. But there are some areas that the diffuser is more tightly stuck to the bumper. As such, the grey tape is not noticeable, but other areas it's not as tightly stuck, and you can see the grey tape. It's not unsticking, but just not as tight. Basically, on these areas, if I pressed my fingers to the diffuser, it would push in and fit more tightly. But when I let go, eventually, it won't be as tight. BTW, I put my expert ms paint skills to good use and threw together a quick pic showing both methods. Any suggestions on what's better/cleaner looking?
If I use the sealant on the outside edges and the tape on the inside, should I make a bead line with the sealant on the diffuser first, then press it to the bumper, or should I stick the diffuser on the bumper with the tape, then use the sealant along the edge next and press it on? Doing it either way makes me think that the sealant will be squirting out onto the bumper once the diffuser is pressed in place, which might be a bit messy to clean up. How thick of a bead line should I make?
How do you keep the diffuser pressed firmly to the bumper? My fear is that I'll put the sealant on press the diffuser in place, hold it firmly as best I can with my 2 hands, but then come back only to see that part of the diffuser moved away from the bumper, and now it's impossible to press it back in place because the sealant hardened? Suggestions? Or do I need 5 guys (10 hands) to hold this in place while the sealant hardens? About how long does it take to harden?
Sorry so many questions....
Looking at it now, I can see where you can say the exhaust is a bit lower. Raising it up won't really work without cutting the OEM cutout a bit. But I see what you mean. I'm thinking it's acceptable to me for now.
Thanks guys !!

Its not that a messy job depends on how much sealant you put on and the excess squeezed out (small bead about thickness of standard pencil). What i did with the excess was create a nice clean bead over the edge of the diffuser and the bumper line with the head of screwdriver soaked in turps. However, you will get places where you will need to wipe away some off the sealant but you can take your time with this as the sealant does not set straight away. As such, you have plenty off time to clean up and manipulate certain areas i.e. duck tape to ensure close fit to bodywork. Where there are gaps in the diffuser in it not being completely straight you might need to duck tape the diffuser to the bumper till sealant sets. Leave to set, and if there are still slight gaps smooth over with sealant and turps. Hope that helps.
In regards to my private message about oem front bumper spoiler/splitter/lip/what ever its called/etc...here is the OEM bumper that I have...same as the pic attached

It would still probably cheaper then doing in the US especially given the dollar has started rising again against international currencies.

What do you all think? Suggestions. Comments. Again please pardon the appearance of the diffuser unsticking on the left side above the exhaust.
Thanks,

Also, if you can't get the part centered or positioned correctly at all, then the mold is messed up. Your only choice would be to fill in the gaps with bondo.
You should just wait. Once more sellers start getting their parts available to the public for us in the US, you'll have more choices. For example, Extreme Dimensions who is a sponsor on this forum will have their W203 body kit out soon. Then all you have to do is drive to Fullerton and pick it up.

When I talked to the other Mike he didn't sound like he was dying to get the kit back. Sounded prettly laid back about it. Anyways, my motto is wait and see...good things come to those who wait.
His first mistake is trying to fit the piece to the exhaust tip. He should first fit the piece to the bumper to keep the gaps to a minimum. Clean the bumper with acetone and then use 3M tape or adhesive. I would just take the muffler off the hanger first and then finish installing the part so that it looks good. Then I'd just hang the muffler up again and adjust the hangers so that the muffler tip is centered. Which would you prefer, spending time bondo-ing a huge gap on the bumper, prep work involved, possibly painting it, or just bend the damn hanger and make the tip centered.
cintoman is describing extra material on the bottom side of the diffuser which shown by his last pic. where's all this tips not centered idea coming from?

he showed the pic because people were question why didn't the other guy did cut the bumper to the diffuser cut-out which replicates the highest of the 55 exhaust placement.
and then I said to him that I think he should still cut the bumper and move the exhaust up to like the cut-out on the diffuser. He said he sees what I'm saying, but is good for now as is.
who said mikey's in a hurry to get it back? you're not making much sense pete.

I think the threads going way off topic.
Last post in the thread for me. Yippee!!!!

As for the body kits I actually replaced my entire front end on my integra and welded on the jdm front end. So i'm kinda over the whole body kit scene.
