I have had a piece of perspex cut to protect my rear window from stone damage whilst towing.
I have been looking around to buy some large suction cups to attach the perspex to the window but can't find what I'm looking for.
Any clues on where I could purchase these ?

You could try a rubber store
I suppose that the suction caps on drain cleaner plungers are too big?Camper

You could also try self adesive Velcro around the edges.

I'd be a bit worried suction cups wouldn't hold well enough, but you might get some as a last resort from crazy clints if you buy some cheap window sunshades, you can cut the shades up for insulation on the inside side rear windows as well.

As somesone else has also noted, I also use self-addesive velco. It has never come off.

Try Clarke Rubber.
I got some there a few weeks ago.
I spoke to a guy who had this type of protector on his rear window and it had been on for 6 weeks of outback touring. Just make sure the glass is clean 1st.

Also try using baby oil or similar instead of water to get your seal. You wont need much, that way it always keeps a seal and will not dry out.

At some of the "CHEAPY" discount stores (Crazy Clints etc) you can get "screw down" suction pads that are aout 45mm in diameter.
I have used them for years (and still do) to hold my upper rod rack onto my roof.
They don't let go! Believe me.
They are about $1 each and they are tough.

Chris,
I got mine from Clarke Rubber. I have 6, and each week or so on a trip one seems to let go. A bit of spit and its right again. I will try baby oil though, and see how I go.
I haven't had any problems with the suction cups over thousands of k's of corrugations. I am sure velcro would work fine, but when the half-brick size rocks come up from those quality Queensland roads I like the large space between the glass and the perspex to absorb the impact.

I was thinking the same thing about keeping space between my window & the stone guard.
What approximate diameter are the suction cups you are using and how are they attached to the perspex ?

Chris,
the suction cups are about 85mm diameter and have a shaft that I pushed thru a hole drilled in the perspex.
The hole is a bit smaller than the diameter of the shaft and the tightness of this contact is enough to keep the suction cups tight.
