DIY Making a Functional Hood Vent/scoop

tools you need
1)metal cutter or dremel tool
2)!!! flux welder!!!
3) some scrap metal

step1 decide what kind of shape you want measure it and cut it with cutter or dremel tool
step2 fold down the piece that you just cut and stick something in between to keep desired width of an opening

step3 get your scrap metal out cut a triangular shapes big enough just to close up the gaps on the sides
step4 set your welder's wire feed from 7 up to 10 and set current on minimum (otherwise you will melt through the hood) weld the triangular pieces in place (you could also use fiber glass instead of welding like this guy here Venting your hood but i don't trust that cause every time you open your hood and the slam it shut the shock created will crack the fiber glass and bondo will chip off and fell out with time)

step5 grind down any imperfections and apply body filler to fill in all gaps and metal deformations after the heat from welding
step6 sand it down and paint

i havenít painted mine cause this hood scoop is just a little part of the big project that i am doing you can choose your own shape and how many of these you want on your hood the hood vents are done the same way its just the opening would be facing the windshield have a fun

well what it will look like is a hood from need for speed most wanted on cobalt ss it had 3 openings for a scoop in front of the hood and 2 vents on the sides close to the rear of the hood and one none functional vent in the middle of those other two vents

Looks good will be interesting to see the finished product. Good advise about using fiberglass part on metal hoods, too many people make that mistake and even pros cannot get the fiberglass to last long with metal without issues. A cheap hack job shows after the 4th or 5th hood closing.

ya dude seriously i was amazed on how many people do this without even thinking i doubt that they ever seen how bondo and epoxy resin works,
Ok now here's possible(means i NEVER TRIED IT on metal so i don't know how it will behave) alternative to welding and fiber glass pepboys have this whitish yellow stuff its called plastic weld i believe, that stuff should work it drys in about 3-5 minutes and cures in 4 hours i used it on my moms bumper cause she likes to scrape all the deeps with her bumper and one day when she was on her way to my house the bumper ripped of course i used this plastic weld and glue that bumper up and she keep scraping all the deeps but the bumper still in place after 4-5 month... should work the same way with metal my friend use it on he's old radiator to seal i leaks and it worked it's just one pack of it is 5-6 dollars and you gonna need a few i'd still recommend getting a flux welder for like $120 or even less but it worth it cause you can do lots of stuff with it even torture people who owe you money lol i am just kidding
