Agreed, might be better.
Can’t find the ones I thought I had, so need to purchase them anyway.

Not that it's worth anything, but you get full marks from me for having a go!

Cheers guys.
To be honest, the lens was just playing.
Saw something on YoTube using roofing silicone and thought I’d give it a try.
Made a full width tail lens for my last project and that didn’t crack, so was surprised when the first horn button did!

I think the paint I added to the lens, stopped it from setting.

I've never done this sort of casting before so tell me off if I'm on the wrong track.
With the horn button if it is thick in places maybe a little less hardener so it cures slowly and generates less heat.
I have watched a show from the States called Fullcustom Garage. Ian the Guru of many things has made many lenses and even big bubble tops for cars with some failures but many successes.
He starts with a mould of the finished outside shape and has a flat section of plywood on the bottom with an air connector going through that sheet. Then there is the top section of plywood that has the final outside shape. HE has also another piece of plywood shaped to the curve to use as a gauge to the end result.
He assembles the acrylic sheet onto the ply and then uses a heap of nuts and bolts to bolt the outside frame over the top. Bolts are the go as tek screws pull out. He then starts the heating process from underneath and once he gets to the temps he wants he then introduces a couple of pounds of air pressure. He keeps this up until he gets the desired shape. My description is rough to say the least but hopefully you get the idea. He even made a bubble top which ended up having 4 different radius on it as he made some bows that stopped the acrylic from going any further .
I agree that the paint has stopped the silicone from curing. Chemical reactions can be fun at times. Keep up the good work.

I was just going to cast it ‘square’ and then round it off, to look like a horn button.
Funny you should talk bubble top cars, my last project was a bubble top.
Although I didn’t blow the roof bubble, I did make a full with rear lens.
Oh yes, just remembered, I did blow the headlight bubbles in the oven.
