Did the 'Raggtopp" treatment today...

[Perfectlap]

I would try to layer the Raggtopp. You know let one coat dry and premeat completely before spraying further.

Also I noticed that when I clean the top with my OXO feathertip brush and the Raggtopp cleanser that it tends to remove the protectant. So you have have to top it off again.

I just sprayed my sunbrella cover with Raggtopp. I use that soft top cover relgiiously. If I know the car is going to sit for more than 8 hours it goes on.
It keeps the windows clean and decreases the dust that collects inside.
I want to protect that top as much as possible, replacing a softop is an entirely preventable expense.
