What`s out there these days or has been out in a spray wax/sealant that doesn`t attract dust so bad? I`m partial to Optimum spray wax but the level of dust is attracts is really getting to me.
I would switch to one of the many spray coatings that are out now. I have been using TW Hybrid solutions spray coating and Flex wax. Both products perform well and never had a issue with dust.
TW spray ceramic is really good and a rain will clean it up well. I did a skylight with it and one with OCW, the TW easily outlasted it by a factor of almost two. The catch is it doesn`t have that nice slick feel that OCW had. Seal N Shine is also good.
And wow it feels weird we`re all now TW fans here. Ten years ago I would have said no way.
If you get your hands on Tac Shinee Wax, I found it to have less dusting attraction. However, you probably need to apply it more often and properly apply as a spray wax, not as a drying aid or quick detailer.
