DIY Rear window vents...

Ok, I have wanted the rear window vents from Rexpeed for quite a while new....just couldn't find myself throwing out 200+ bucks for a set. I had some Ideas on how to make them, but never started until now. Here's the how-to that I have so far...I 'm just now finished with the first half of the process, but I will post the rest when I finish.....Give me a few minutes to upload pics........

 

Step 1 Tools Needed:
DOW styrofoam insulation board
Tape measure
Marker or pen
Exacto or loose razor blade

First go to Lowe's, Home Depot, Etc. and pick up a sheet of the DOW blue styrofoam insulation board. Its sold in a 4x9 sheet for around 7 bucks (the extra makes a great pad for lying on the ground while working). I had some lying around the house from other projects, found the best piece and went to work.

when you're ready to start marking and cutting, you can use the board itself or a piece of cardboard to make the template. Make sure you pull the layer of plastic from both sides of the styro.....a lot easier. I know the length needs to be roughly 25 inches for the 7Gen rear windows....height is purely up to you. Once you have the basic shape, put it into position and check the fitment. I went through 3 before I got a good fitment...lol.


Also check how far it extends from the window...you only want enough to be flush with the door trim....


Next is another variable. Decide what size and how many holes you want in the vent. Whatever you choose, keep an even space from the top, bottom, and the other holes to help make sure it stays structurally strong. I went with 5 holes...don't exactly know the diameter...I just traced around an old can I had lying around.


When cutting the holes...TAKE YOUR TIME!! Try to keep the board as flat as possible, to avoid breaking it. I had 3 holes done, and went too quick on the fourth...and had to start all over. After you have the holes done, check the fitment and looks of the piece. If you don't like it, you can start over...adding more holes or taking some out.





That's as far as I have gotten as of now. The next step is going to be final shaping and fiberglassing over them. When I get to that stuff, I'll keep this going for you guys....

 

I haven't had time to finish them...but so far I only have about 30 bucks in them.
7.00 for the foam board
15.00 for the fiberglass resin
10.00 for the fiberglass fabric

All I have left to do is fiberglass, sand, then paint them....The wife is off this weekend, so I might try to finish them then...

 

Nice job Molina. And no, I haven't finished these. I've got them shaped and ready for fiberglass, but haven't taken the time to finish....but it's springtime now and could use them, so I might pull them out and finish.

 

I don't see why not.

 

To let air circulate through the cabin without fully rolling the windows down. They will pull fresh air through the cowl under the windshield and out of the dash vents.
