Yow fellas. I am trying to find out some information regarding automotive paints and in particular - the clear coats that are available here. I had my car painted in Jan of this year and up to now - I have gained some scratches on my doors due to tricycles moving in and out of my garage

. My painter sourced the paint materials and he said he used "PPG". In most cases the clear is scratched, but in a couple of spots there are slight gouges in the paint work too
I suspect that my problem is (apart from the tricycles and their respective drivers) is the (a) thickness of the clear applied, and / or (b) the resilience of the clear.
I have another car which I need to flash over, but I want to make sure I go with a strong system this time.
What recommendations you all have for paint - and/or clear coat systems that are available locally - that won't break the bank.....? Meaning - brand and line / series.... TIA.
