EvilRufusKay Posted September 20, 2004 Share Posted September 20, 2004 How long did it take you to smooth out your cowl? So far I have about 1.5 hour into mine and its almost done!!!Last link on bottom Quote Link to comment Share on other sites More sharing options...
blueovalz Posted September 20, 2004 Share Posted September 20, 2004 When you "prepped it with POR15", what is it you did? Is the mat laid over the POR15? If so, can you elaborate? Quote Link to comment Share on other sites More sharing options...
Mikelly Posted September 20, 2004 Share Posted September 20, 2004 Terry, I was thinking the same thing... Russ, you might be re-doing your work on that cowl... Please elaborate... Mike 8) Quote Link to comment Share on other sites More sharing options...
Tim240z Posted September 20, 2004 Share Posted September 20, 2004 Rufus, If I were to do it over, I would not have cut out the vents and holes in my cowl and then welded in patch panels. The cowl is so flimsy and even carefull welding warped it, and sanding it was very difficult because it carries over the hood bulge, so it is very difficult to put pressure on it to sand the filler without bending it. I would instead, just tack a panel under the vents and fill the vents with Duraglass...... If that fiberglass doesn't separate, you will be in good shape.....

EvilRufusKay Posted September 20, 2004 Author Share Posted September 20, 2004 I wanted to make sure the matte would not be affected by moisture in the future. So I cleaned the cowl, used POR-15's metal prep, and then coated the surface with POR-15. After it dried for a couple of days i began laying the matte. I knoe POR-15 has mixed results. I have had varying levels of adhesion myself however, on spots that I was careful in prepping it has very good adhesion, especially on light suface rust that was prepped right. The underside of the cowl had a slight dusting of rust so I am confident it will stick well. The POR-15 does not seem to do as well on sheet metal that has nor corrosion. I take it you guys think I may have "screwed the pooch?" Thanks for the input... Rufus Quote Link to comment Share on other sites More sharing options...
Mikelly Posted September 20, 2004 Share Posted September 20, 2004 I'm thinking the POR15 is gonna seperate and allow the matting to delaminate from the sheetmetal... I'll do what Tim suggested... POR15 is a product I'll not use again... The stuff is very unpredictable... Their metalprep is the only stuff I'll buy from them.

EvilRufusKay Posted September 20, 2004 Author Share Posted September 20, 2004 Well I guess we will wait and see.... Luckily if it does begin to delaminate the panel is eaily removed, and repainting it would not be too difficult or expensive. Is there a method for removing the matte if I decide to take Tim's advice? Quote Link to comment Share on other sites More sharing options...
Owen Posted September 20, 2004 Share Posted September 20, 2004 I hate POR-15, one of the first products I bought when starting my project and it sucked...if you apply it to flimsy metal, it peels off! One thing you can try to remove the matte is heat. I've used heat guns on the backside of metal-fiberglass bonds to remove stuff, works pretty well. Otherwise just flex the metal little by little and it might delam that way. You're already using fiberglass, why not just make an entire fiberglass cowl? Here's what I did for my hood, http://www.v8zcar.com/s30z/aero-hood-pt1.htm Owen Quote Link to comment Share on other sites More sharing options...

You all ready have the mold. Just put glass all the way to the ends. (Do some research first.) Quote Link to comment Share on other sites More sharing options...
EvilRufusKay Posted September 21, 2004 Author Share Posted September 21, 2004 Only one reason...I already have enuff on my plate!!! Hey....if it is as easy as you guys say it is...by all means....... Rufus Quote Link to comment Share on other sites More sharing options...
Owen Posted September 21, 2004 Share Posted September 21, 2004 It's almost easy, I say almost cuz you want to smooth out the vents. Just make a straight glass copy of it, sand away or glass in the vent holes (which will remain from the original) and you're done! I would fill in the wiper holes with bondo, sand down. And then grind down the backside of the vents, fill with bondo, sand down. Then lay the glass over it all. Only issue I can think of is the mounting tabs that fit in the holes under the windshield, not a big issue really. Owen Quote Link to comment Share on other sites More sharing options...
