scooby_doo_do Posted February 22, 2004 Share Posted February 22, 2004 I think this is one for Dude, but i'm sure some of the old timers will know a little bit about patching up holes on rusty old cars :-) .. My old Le mans chariot has got a hole underneath the accelerator pedle. My BMW has just been sitting on the drive now for over 6 months and it still started first time and passed its mot (not bad for a 1984 525e ) Anyway.. back to the story. I filed down the hole and cleaned up the rust as best i could, then used some wire mesh with lots of that fiberglass stuff that is sticky as hell and goes everywhere to fill up the gap. I plan to then use a can of underseal stuff i bought to cover it up. But.... Can you sand the fiberglass down to get rid of the sharp pointy bits that are left or will it just break up ? And do i have to do anything else to it ? Thanks. Quote Link to comment Share on other sites More sharing options...
Performa Posted February 22, 2004 Share Posted February 22, 2004 I believe that you can rub sand paper against fibreglass once its dry up. Although i have not done may fibreglass work but i remember helping my friend building his bass box and gauge pod with some MDF and fibreglass. Works fine, very dusty make sure you dont over sand it and your wire mesh felt on the floor though. good luck Quote Link to comment Share on other sites More sharing options...
scooby_doo_do Posted February 22, 2004 Author Share Posted February 22, 2004 Cool, Sanded all the sticky out bits off and then decided to underseal it... Only, i found out that the underseal spray is a complete nightmare, especially when the winds blowing at you and the stuff goes all over the place.. Covered head to toe in black gunky stuff that doesn't wash off..... Nice.... Anyway, All sorted now and the bmw has no more "cough" noticeable holes!

Performa Posted February 22, 2004 Share Posted February 22, 2004 Sounds like you have some fun with that black stuff. i could imagine it must be a b*****d to clean off your face afterward. nice to know you (your BMW) are away from coughing Quote Link to comment Share on other sites More sharing options...

Terminator Posted February 23, 2004 Share Posted February 23, 2004 Much safer and MOT proof to get it welded. Quote Link to comment Share on other sites More sharing options...
TLicense Posted February 23, 2004 Share Posted February 23, 2004 Bit late now, but wear a mask when sanding down the GRP. You don't want glass fibres in your lungs. I s'pose you were doing it outside so not so bad , but one for next time. Quote Link to comment Share on other sites More sharing options...
scooby_doo_do Posted February 23, 2004 Author Share Posted February 23, 2004 Errr.yea, Forgot about the mask... But was outside and standing an arms length away... As for the MOT situation, its got nearly 10 months left..... You can't tell the diffference now its all undersealed. All in all it looks ok.... Best not accelerate too much though as the pedle might go through the floor.. Only need the car to get us to le mans and back.... Hopefully not a problem I would of tried to weld it, but i have no welding tools and haven't got the fogiest how to weld....I'd prob set the car on fire or something ... Ta chaps.. Craig.
