Paint correction - what do i need to buy? And hard water Q

BrandonSS

I always wash the car in a self serve bay at Mike's and never dry with anything other than air OR I wash it at home with a wool mitt and again air dry.

However, the car is riddled with swirl marks and it needs fixed. I used my generic mequires compound and it's not making any impact.

So, what do I need and where do I get it? Someone help me with a shopping cart list.

Thanks!

Oh and the line to my garage is not on the softner line, so it gives me hard water. I thought about rigging a RV style filter in line but curious as to what others have done. This is primarily why I have been going to mikes since their spot free rinse is filtered.
