Anyone else with a soft top convertible like to renovate alongside me?

Hi. I’ve a soft top convertible with a really dodgy/dangerous back plastic window. It’s now so scratched and cloudy that I have to open my drivers door to look out when reversing/keeping my fingers crossed/using side mirrors and hoping for the best. If anyone out there has the same soft top car issues and wants to sort their back plastic window out DIY style and would like to share the cost and the workload of doing so… please PM me (PM’s only please). I’ve found a really useful vid that recommends a great product and how to use it. I’d like to go ££halves on the labour. i.e. because of my back disc issues, I’d find it difficult to apply the product to the inside of the back window - so I will do both mine and your cars’ outside windows…if you do mine and your cars’ inside windows. Plus, share the cost of the products needed. Anybody interested?
