I'm getting ready to do a bike, the owner wants a solid candy-apple red finish. I am thinking I'll spray a silver metallic basecoat, then use a HOK candy red (I have/have used their Tangerene candy before). My Q is this: After I spray the candy red, what if you have a dust or dirt nib in the paint? I thought I heard you can't let it dry, then very wery gently sand it out with say, 800g or 1000g, it will ruin the uniformity of the candy color. Any truth to that? Why do the (HOK candies at least) have a reducer AND a catylist? They need to be topcaoted with clear, so why the catylist as opposed to a 1:1 basecoat type mixture????
