Ok I have tried afew different things in my years of fiberglassing. I have no problem throwing together a box or kicks or pannels or anything really quick. made new tweeter pods to replace factory pods but fit like factory last week took 45 min to do both sides. Not to long... Spent 6 hours bondoing and sanding what was an almost perfect serfice to begin with (used grill cloth gets you that much closer to smooth) Basicly all we need is some form of THICK primer or deluted bondo that you can spray on. I have read about deluteing bono with alcohol and you can spray it then the alcohol drys off. Scared to try this don't want to ruin a $150 paint gun. Also tried mixing fiberglass resin w/ bondo and using fiberglass hardner, works decent you can paint it on and it drys nice and hard. However for small applications this is pointless and once again you STILL have to sand the **** out of it. Does anyone know any product that you can just use grill cloth as your outside serfice paint it down w/ resin let it dry then hit 2 or 3 coats of some imaginary thick primer and then light sand and ready for paint? This is what I am looking for and if anyone knows of any of these types of products make a post send me an e-mail email@example.com hell im me mayday0017 I'll pay for it in answering any questions anyone else might have. I just know that Rockford changed their whole line which means we will be getting all new product in, in the next month so that means time to gut the car and do it all over again.
