Tar remover? Pffff....petrol all the way.
Spray on leave a few mins and wash off
Petrol is a bit harsh... and can attack some kinds of paint. I'd go for paraffin (kerosene/aka "Turpentine Substitute" from the local B&Q) instead. It's the active ingredient in tar remover anyway.. just you're not paying for the fancy label.
Paraffin is excellent stuff. If you have any left over (and you will... since it's about £2 for a litre) you can add 250ml to each tank of benzina as an injector cleaner. Paraffin is the main actiive ingredient in Injector cleaner anyway.. just you're not paying for the fancy label or the red dye.
But we digress:
Wet - Shampoo - Rinse - Dry - Clay - High def cleanser - Super resin - Ultra deep shine - Extra gloss protection - HD wax isn't bad but as has been said, there looks like some duplication.
I'd go (brand neutral):
Wet - Shampoo - Rinse - Dry - De-Tar
- Clay - Cleanser - Polish - Filler - Wax
To de-tar.. all you need to do is wet a clean cloth and dab the lower sides of the doors, to dissolve rather than "abrade" the tar spots. You won't have significant tar anywhere else so you don't need to do teh whole car. Remove the kerosene residue before claying otherwise the clay "picks up" on the solvent and becomes contaminated.
Clay is mandatory the first time.. later you'll find the paint doesn't need it again for a while so you can leave that part out (just wash-fill-wax).
Polish is an abrasive (rub).. Filler is a coating (wipe).
If you have SRP then that's a good "filler-polish" but it does make a lot of white powder (you have a black car) and arguably it's an "all in one" (Jack of all Trades) product for "amateurs" rather than someone serious.
A dedicated polish (choose any from the millions of different personal opinions..
) followed by a dedicated "filler" (you can do a lot worse than Poorboys Black Hole) might arguably do a better job but if you have 5 ltrs of the AG-SRP stuff, you can still use it. It's quite good really.
For wax, there's as many opinions as posters on here. I use Natty Bllue Wax as it does last ages... don't listen to Simon..
It's easy to apply and wipe off (no smearing, pretty minimal dust and smells like bubble gum - can't be bad).
You need to apply 4 coats for massimo intensita. Yes.. really. But you started it.
Let each coat "cure".. rub it off. Repeat. I went up to 7 coats once.. but 4 is where you can't see any further improvements.
Guaranteed it will rain the next day.. but you will have the tightest beading in England..
