just had 7 glorious days on Fraser but the pop top got exposed to tree sap any remedies. Noted it on day two and set up some cover but cannot get the sap off the roof of the van- fibreglass and canvas top of bed ends. Any ideas and yes I should have used the storm covers but it was not raining......

Cheers

Yes, but then you put them in the washing machine.

True, but you need an organic solvent first to remove the sap. Then you use soap & water to carry it away then you dress the canvas with a repellent.

bit hard to place into a washing machine but will look for an organic cleaning agent perhaps one of those citrus washes like Big Kev ?

The Eucalyptus oil is organic. The citrus or similar may also work but you only need a few spots here and there. You would probably have to use a canvas dressing to make it water tight after using a detergent (or any) cleaner.

Shouldn't be hard to get it of the fibreglass, warm water should do it, if there is any residual stain, you may have to acid wash it, or use "Fibreglass Restorer".
As far as the canvas goes, it will be harder, I would just try warm water, or in my case the sap really hardened in the sun & was able to be brushed off, left a faint stain, but I can live with it, although I am sure it is fading with age.

HI Wayne,

I'm sorry I can't help with your sap problem but the picture of the red 4x4 in your post caught my eye. A sixty series!!! I have a 1988 model turbo diesel (factory). I checked your Rig profile and note you have gas injection - something I am looking at. Have you been happy with result? Is there a noticeable increase in power? Overall is the engine running better (cleaner)?. Also I have been researching the two types - any reason why you chose the programmable type rather than the mechanical type that injects based on turbo boost (seems a simpler method to me). For the later I have been looking at Eco-shot. Any thoughts appreciated.
I am near Brisbane.
Cheers,
Glen

Hey Glen, I went on the recommendation of a friend who said you could not go past Dallas at www.teamgreenautogas.com.au. His truck is also a Toyota although running a V8 diesel.

Performance is more than noticeable and I went with the system Dallas recommended and the Dyno speaks for itself. Give Dallas a call and he will take you through the pro's and con's and he keeps all his dyno runs so feel free to take a peak at mine. The truck runs brilliantly and is getting good mileage. The truck does blow more smoke at lower RPM although I put this down to motor age and injectors.


Regards

Are there any Botonists amongst us that can tell us exactly what Sap does with age ?


I have been told ,, never wash canvas,,

It will loose its water proofing quality.

My suggestion is to cop the sap, unless there is absolutely heaps of it. You may have to wait till it goes brittle, then flick it off.


What happens when it gets a hot day on it ?
Does it soften ? ,,
Does it go brittle ? ,,
Can it be flicked off ? ,,

I too would be interested, but I do not camp under trees.
I consider it too dangerous.

Cheers
Bucky

Unfortunately most substances that take tree sap of canvas also remove the waterproofing and colour, especially stuff based on hydrocarbons or soap.

the best advice i can give you is water and a soft brush to scrub it with so you do not remove the waterproofing. On vinyl surfaces , try window cleaner. (I have 40 years experience in the manufacture and repair of canvas products)
