Nice one Stripe.
Gtechniq GWash is a really good PH neutral shampoo and will suit the coatings well.
You will also need either C2V3 or their new Easy Coat to top the coating now and again. The C2V3 may seem expensive but can be diluted down to produce a decent quick detailer and/or drying aid for every wash. All good stuff and if you don’t live far from me, I can sell you some C2V3 cheap as I bought a gallon last year for about £65 which will last for ever for me.
I’d also invest in some of their Citrus Snow foam too. Again, decent stuff that will work well with your coatings.
