try using meguiar's scratch-x swirl remover. yun ginamit ko to cover up mga circular na swirl marks sa hood, tanggal nga. Then applayan mo ng wax to seal it sa paint.
run you fingernail over the scratch, if you can feel it, it already went beyond the clear coat and its too deep already that only a repaint will remedy it.
if not, use the mildest scratch remover that you can find first. try 3m, eo, mom's, or meg's. if that doesn't do it go for a bit more aggressive rubbing compound from the said makers.
Nope. Touch up paint is DIY gadget that you can use to cover deep scratches na di na kaya ng mga compound waxes. Para siyang Pentel pen na susulatan mo iyung mga scratches. Others have small brushes na parang sa cutix ng mga manicurista. Pero pentel pen lang ang sizes kay 250-350 lang ang presyo. Concorde has these gadgets.
