When I was a kid, back in the 70's.. There was no pouring foam.. fiberglass was everywhere, but now, foam really changes the game in composites.. A few years ago, I made an entire Hovercraft from foam/fiberglass composites. it was amazingly strong and light weight..
Thanks for the repair Dad. It's great to know all my shortcomings are video'd in detail, then edited and put on to TH-cam for all to see!! I guess with such an informative video, I'm running out of reasons not to do this type of work myself. At least I will be able to control what gets published and what doesn't!!!! Oh and by the way, some of the "extra" cracks are simply the way the bar contacts my alloy duct work, but I know you're smirking at that and don't buy it for a second!!!! :)
Thanks buddy. That's why I produce these films. So let your creative juices flow. Expect mistakes and problems when working with this stuff, but if you're not afraid of it you can do things with synthetic fibres & resins that are only limited by your imagination. But beware of all the "little"jobs your friends will soon bring to your door. They usually end up being time wasting nightmares.
Asking questions is not ineptness but how you learn. Fibreglass will not stick to moulded plastic bumper bars which are made to be super flexible. I've tried roughing it up & drilling holes through it, but that's all a waste of time because it soon seperates. I'm not sure if pouring foam would stick to it long term as I've never had to try it. It may or may not work.
Yeah, I knew all that, but I've still got a club member here who insists on using epoxy resin with csm in making a complete kit car body. Some people just don't wanna know!
All I could show you to finish that front bar was to mould and copy it, which is exactly the same as what I did later in the vid with the Midget front end, Just fast foward from where I stop working on that green bar to painting the Midget front with resin & you've got all the steps. I've also demonstrated what to do in my other tutorials.
Very informative - some neat techniques. Just to be pedantic, by "fibreglass" resin, you mean polyester resin, as opposed to epoxy, (though I see even some suppliers refer to polyester that way). You probably know this, but for the benefit of others, it's important to check the compatibility of resins and cloths. E.g., epoxy dissolves the binder that holds CSM together. A quick check online will usually tell you what works with what.
That's a pain, Plastic welding it is I guess. Thanks for the response. I asked regarding the pouring foam because my car's bumper (little daihatsu charade) is more fragile than a popstick and was wondering if that'd stop it from cracking at any given point. Thanks again
Dear sir my name is amit from india and like your all videos which is about fiber glass and repair our car panels please advice can I remodelled my car and where can I buy these product. Thanks Amit
I have no knowledge of what or where you can buy f/glass products in India. You need to search for a fiberglass materials supplier to the swimming pool or boat building industry in a major city is all I could suggest.
I have a similar car, you can shave weight from the bonnet, make a thin one so it's light. Engine components like air boxes can be made from fiberglass too. Even the dashboard and seats can be made out of this material.
I haven't found it necessary to grind out cracks because the strength of any repair depends on the bonding of the new work to the old. A widened crack with new material in it doesn't add to that. The strongest repairs are where you grind out the crack or drill holes in the original body piece and put new glass on both sides, making a sandwich interlocked by the resin. This is just ONE way to do a repair, but I honestly haven't had a single sided repair fail in a decade of doing it this way. T
Sorry for my ineptness at this craft but could you do a similar repair on a standard plastic bumper bar? Or would you have to look into plastic welding? Thanks. Also would any expanding foam do for the strengthening (from a fibreglass supplier that is).
I'm assuming that race car repair is not as permanent as other repairs. HUH ? What I mean is ...shouldn't you grind out the crack and then fill that to build up the original thickness and strength..........that's what I do
No no no - the aerosol foam will NOT work. It's aeriated by air rather than by chemical reaction so it's adhesive and strength qualities are crap. Pouring or expanding foam is something you'll only get from a secialised seller, but I just Googled ëxpanding foam supplies Victoria" and got heaps of leads you could follow.
Love old skool lessons like this! You've just helped me do my own work to my Evo bumper! Thanks from Scotland champ! :)

Has to be the coolest and greatest dad ever! Makes you want to go for a beer with him!
Wish i saw this about a month ago, did a similar thing but now i know how to make it stronger.
Cheers mate
Love the tutorials, thanks for showing the process.
Excellent video and very informative! Thanks!

Congrats a thanks a lot for your vídeos. Really motivated me to have a go at trying to make a bonnet and a tailgate for my Capri ;)

My short term memory is shot - but if you think I've forgotten you driving my VW Golf clubbie into a tree... what can I say? What goes around....
excellent!
We sell it at my work in Newcastle. Where abouts are you in Oz?
The rigid one looks the go to me.
awesome
