I'll stick with Citrus Power then (maybe dilute it), Tardis, Iron X and just use Black Hole and leave the polish for now. I'd rather decrease/mask swirls especially as it'll be for sale soon.
Oh right I thought Iron X and Tardis would be used at every wash. I'm unlikely to wash it anymore than once every 2/3 weeks. So I'd only need it every couple of months when reapplying wax/sealant and just do a wash inbetween?
If I was to apply Black Hole every couple of weeks for the first 6/8 weeks to keep bringing the condition up then it'll need rewaxing/sealing? So it's worth using Tardis/Iron/Clay all again to give a smooth paint finish for glaze and sealant?
How would one apply it properly? A spray sealant like Tough Coat as per recommended will be a lot simpler and better for a novice?
Sorry for all the questions guys, I really appreciate the help! Thanks.
