Mr Sheen is full of silicon too.

You can never reprint a car that has been polished with Mr Sheen (and we used to use it to polish motorcycles in the shop I worked at.

Plexus can be found in most major motorcycle shops.

I'll also give a vote to Auto Glyms red microfiber cleaning cloth. I have had one for years and use it on everything. I must make a specific exception as regards to canopy plexiglass though.

In reply to the OP, I used to buy Plexus from TransAir, and now they only offer ClearView. I cant tell the difference. It seems pretty good to me :-)

We have used mr sheen for years at work and the aircraft have been painted many times without problem. It's all about preparation when painting......

Duraglit will polish out deeper scratches, Iused to fabricate the canopies for premature-baby incubators..that's what we used after trimming with a router,sanding with fine wet-or-dry, buffing on a mop and finally hand-finishing with Duraglit.
We used the American Oroglas (same as the Bell "whirlybirds" bubble canopy) It was softer and more malleable than ICI's Perspex which was brittle by comparison

Asides- Oroglas featured in the infamous Summerland leisure centre blaze on the Isle of Man...the building was entirely glazed with it and melting/burning sheets flopped out of their frames onto the trapped holiday makers below.

being bored one day, i noticed a wasp taking an unhealthy interest in some discarded Duraglit wadding.....trapping a wasp in a vending -cup and feeding a fresh piece of wadding in, one observed the wasp in a feeding frenzy, followed by total disorientation and death...they must have got drunk on the solvent-content, 'cos with a bit of practice, one could tip'em iut on the bench and watch their antics until they eventually recovered sufficiently to lurch into the air*

"Aviation content ;)
