I'm doing this http://forums.nasioc.com/forums/showthread.php?t=1076142&highlight=pilarless+grill And I want it done tomorrow if possible *Correction I want to do it tomorrow if possible*
on that thin of material i would use very light applications of bondo and spend the most time on light sanding and sculpting...you can always replace the bondo if you sand too much..its easy enough to sand. also i would reccomend tack clothe and glazing putty...and maybe 400grit or finer sand paper..try not to scratch the plastic.
its easy, sands easily, applies easily, its just easy, but for you chet....its wayyyyy too complicated
Welding plastic requires knowing what kind of plastic it is and getting the appropriate filler. Now if you are trying to use some sort of goop, have fun with that. I'd just assume use JB Weld if you are going that route. I don't know how Bondo brand stuff is these days. I usually just go buy some lightweight body filler. How long it takes to harden depends on how much hardener you put in it. I usually mix it so it is sandable in about ten minutes.
thats why its called PLASTIC welding... basically melting 2 plastics together.. a lot harder then it seems.. Chet bondo is easy.. read the label on the can... and be patient
^ That. You can weld plastic like you can weld metal. A little bit different process, but same idea. Like I said, if you put in a "good" amount of hardener, it will flash rather quickly. It takes very little to begin with, so an extra teaspoon can make a huge difference.
