Second coat of paint fail

[Colin]

I was painting my FOTK with the recommended spray paint and gave one of the bicep pieces a second coat after sanding it but it's still cracking and not adhering correctly. Does anyone have any recommendations on how to salvage this piece?

Not sure what recommended paint you have used but many paints need to be completely dry before applying another coat. Also wash everything in warm soapy water to get any grease or finger prints off. Did you scuff the surfaces first with sandpaper, this allows the paint to grip better, I normally will go over with 600 prior to adding primer, which leads me to the next question are you spraying directly onto the base or have you added a primer first?

I used Rust-Oleum painters touch white gloss paint and primer as well as a high grit sandpaper, thank you for the advice for the other pieces

I've had all sorts of problems with Rust-Oleum paints, mainly not coming out consistent and occasionally spraying like a sand, that's with shaking the can for 10 minutes prior to using as well as between passes of paint, I always thought it may be out of date paint as it's not widely used down under. It really doesn't like having multiple coats unless it is completely dry, I would say leave for at least a day if not longer.

 

I hear Krylon paints are a little better, we don't have those here so I can't offer advice on that.

 

Many years ago I swapped to automotive acrylic spray paint, dries quicker, can buff and polish if needed, but like any paint it does take some getting used too.
