Actually your being a bit optomistic, all the damage to the paintwork has been done (by TCut and Poundland cloths) so you really need to start from fresh, you need it machine polished to remove swirls and other defects and then wax or seal ontop.
SRP is good at masking swirls but it wont remove them (hardly) and it'll also wash off as its not a sealant or wax. Ive got dodo juice purple haze but would opt for zaino all day long. Much much much glossier, lasts longer and is easier to handle.
