Painting spider vanes

[glnn_23]

Hi all,

Having a go at putting my first newtonian together and have decided to use protostar flock board to line the inner of the 3 section tube.
Can someone please tell me if you need to prime stainless sheet made spider vanes or can you just spray on flat black enamel.

Thanks

Glenn

Not sure about Enamel Topcoat on stainless without a primer basecoat
Would use a primer that suitable for stainless steel.
Could use something like an Epoxy primer that also for stainless steel or Dulux Metalshield Etch Primer Spraypak.
Instead maybe a Epoxy flat black paint suitable for stainless steel that doesn't require a primer.

Suggestion: Could first clean stainless with Prepsol, then sand with 320 non-silicone sand paper (for paint to adhere better), then clean again with Prepsol, then wait about 15 minutes for any residue of cleaner to dry before Painting.
Clean with Prepsol first because sanding any contaminants on surface could cause them to spread and embed into sanding marks, harder to clean before painting.

your 3 arm curved spider design is nice!

Thanks LesserBear for paint and preparation info, very helpful.
I was hoping to put the least amount of paint as possible on the vanes but it looks like I'll need to prime them first.
Cheers

Hi Lee, thanks for the link. That article pretty much covers it.

If using something like Prepsol the rags could leave fibers on surface, could use a 'Tack Cloth'(Wax free and silicone free type) to remove lint or dust for very last preparation before painting.
