Hey Spray Painters! Question on Gloss clear coats (rattle cans)

electronictofu

Hey all,

I've done a ton of painting with HVLP and rattle cans. For this project Im doing a color change on my motorcycle tank. I am doing gloss black. I was planning on using a Dupli-color or RustOleum rattle can black and a 2K SprayMax high gloss clear.

With this combination, and using a high gloss clear, should I be using a flat, or satin black paint then lay the gloss clear on top? Or gloss black paint Dupli-color and sand that before shooting my clear? Or is it gloss clear coat on top of gloss paint? I can't recall the basic process, with this combination.

Thanks peeps!
Phil

If you sand the color coat before you spray the clear coat it can leave texture that can show in the clear. If the chemistries of the paints are compatible you can spray the clear over the color within the color's recoat time.

That's what I was worried about is sanding the base coat and marks showing. SprayMax 2k clear says comparable with most paints and surfaces. I think like you mentioned timing is key, spray a gloss clear over a gloss paint, just timing before shooting it sounds like it'll be good.

Sanding is good before the finish colour coat, in my book anyway -- but not between the gloss colour coat and the finish clear coat. The ringer in the deck is to use fine sandpaper -- and I do mean fine. 400 to 800 is none too fine. You're not trying to smooth that finish colour coat finish much, just break the surface enough to get decent adhesion.
