Can I use it regularly?
Yes, whilst Lime Prime contains micro-abrasives, it is made to remove swirls no more than 1 or 2 microns deep in your paint; even if machine polishing every few months, that normally means 20-30 sessions before you are likely to strike through a modern clearcoat.And hand application really won't cut much at all in comparison.
Will it strip wax?
Yes, it removes old wax layers while polishing. Even if some old sealant still persists, it will be so clean and keyed that you're likely to be able to wax or seal over the top without issue.
Is it suitable on soft paint?
Yes, just use low pressure and soft pads - and ensure it is fully worked. You may create micro-marring if it isn't worked enough. If in doubt, grab Critical Finish polish which is even gentler.
Do I need to seal afterwards?
Yes, always follow up with wax or sealant for protection.
Should I panel-wipe after application?
Lime Prime fills the paint to give a better finish, but you may want to perfectly refine the finish by polishing fully before applying a fussy sealant. In this case, panel-wipe after Lime Prime with Stripp-Ex. The sealant will then bond to pure paint and not a slick of glaze oils, maximising longevity.
