Use with care! What do you need to use it for?
I went through the clearcoat on my old 309 GTi trying to sort a scratch with it.
An old fashioned type abbrassive, ( like T cut but more user freindly) it keeps a fairly course cut no matter how long you work it for unlike some newer polishes which breakdown into a milder finishing polish as you work them. You will probably need to use a milder polish to use after it to remove the finer marks that it installs removing bigger ones.
Sounds a plan, see how the SRP brings it up first, Try a couple of applications of the SRP in the trouble areas before you crack open the Paint Renovator.
Just use the Paint Renovator with care then mate. As a rule as long as you nail does not catch they should come out. Let us know how it goes - Will have a look Sunday for you anyway if you like?
