For some reason a pillock has fibre-glassed the front inner arches of my car. This has semi-permanently fixed the wings to the inner wings and the wheelarch if that makes sense to you. I need to remove the wing (obviously..) but the fibreglass is in places 5mm thick to 10mm thick. The inner wings are actually in very good condition, as are the outers in terms of rust but the front valence contains roughly about no metal whatsoever. Just fibre glass and filler. And rotting steel that wasn't even treated before covering in crap.
So how to get the 'glass off? Any chemicals that break down the resin? Does it burn? I've been hacking at it with a chisel, hammer and angle grinder but apart from inhaling vast quantities of presumably rather toxic dust I've not had much luck.
Thank you

Paint stripper.

Is that on the Capri?

Sounds a complete pain, but could you hacksaw through it if it's 1cm thick?

yes pushed a fibreglass (glassfibre?) boat onto a rather large bonfire once. assumed it would burn. burn was somewhat of an understatement. the plume of black smoke was visible for about 3 miles. even a local longbow changed course to have an oggle

you may have to use a blowtorch to get it to go, but i wouldn't fancy your chances of stopping it once it takes hold inside the wing tongue out

Hire/buy/borrow an oscillating (aka rotary reciprocating or bone) saw and you will easily cut it and minimise damage to the material beneath. I've used them plenty of times for cutting GRP.

Apache? Awesome!

Mmm maybe firing it is not so good then.

Re saw thing, any links? space is tight, will it fit into corners and edges?

Paint stripper will that melt the resin so I can just pull out the matting?

indeed, AH-64D's. must be american pilots as they have to follow the A12 up and down to get about, and i swear they'll hit the phone mast next door to my office one day.

how much of the wing can you unbolt? maybe you could unbolt the majority of the top then soften the glassfibre with the thinner/stripper to get more access/movement to the rest of the area?

Wow! I'd love to live somewhere you could see machinery like that. Best I get is chinooks overhead when I'm working around london bridge. Sound incredible though.

The wing is all unbotled, had to hack through 'glass to get to the inner bolts! I've cut through the welds around the headlight bowl, and to the front valance (custom front end) but the wing hardly budges still. Will have to stick my head inside the arch and work from there.

The saws look like this: http://www.oandpenterprises.com/oscillating_saw.ht...

That one is pneumatic but the electric ones look the same. Tight corners aren't great but edges are easy. If you've ever had a plaster cast, it's likely that one has been used to remove the plaster.

If you are near any boatyards, you might be able to sweet talk them into letting you borrow one of theirs for a little bit.

Handy thread, Iv just bought a T4 VW to turn into a surf bus but its an ex fridge van, got all the insides out but still some resin and matting left around the edges where the pannels were glassed into the dor shuts to make a 'box', was going to look at B&Q and see if they had any sort of de-bonder, just something to melt the resin. I know theres something in a surfboard repair kit Iv got that cleans the resin off ur hands but no idea where it is or what its called, probably not strong enough to melt it off a car anyway.

Brilliant, cheers. It won't fit though! Thanks for linky.

Off to Halfords now for stripper

You can get a similar thing made by Bosch from B&D/Homebase etc that comes witha variety of blades.

One is about 3/4inch wide and 3inches long.

It does come off the unit a right angles though.

There are a lot of blades available.

Do you know what sort of resin has been used? If it's vinylester or polyester then a heat gun might be enough to begin softening it up. If it's an epoxy resin, it's going to be a whole lot harder.

What sort of cloth has been used? Again, a chopped strand is possibly going to be harder than removing a woven cloth.
