yea if its galvanized steel flat sheet than you got the right stuff but i only paid 10$ for a 2 foot by 3foot sheet, i sliced my hand like 4 or 5 times when i did this also...im using rubber tubing for insulation and it looks like its doing fine....I just got 4 stiches from doing this lol. But its still not done. I have a few questions though. 1. I paid $23 for the steel at home depot, did i get the right kind ( galvonized steel )? 2. My freind used the foam insulation tubing and it melted, what material do you recomend?
im not sure how good fiberglass would keep heat out...they way i did mine keeps heat out like a masterpiece, after a long trip i put a hand on both sides of the shield and the temp difference is insane! the filter side is nice, cool and fresh, and the engine side is almost too hot to touch...would fiberglass keep the heat out?
and does the bend matter? ive seen a straight one.. 60 degree.. 90 degree.. ect.. which would work best?
