General topics » Advice on painting luggage?

I've finally been repairing my bike luggage, damaged in last summer's off, and have progressed successfully as far as painting, at which point it's just all gone horribly wrong. Using rattle cans and knowledge gleaned from the interweb, I've painted the panniers and topcase with etcher, several coats of grey primer - all good), and finally the first coat of lupin (it's water-based). As is apparent from the pic below, it's gone all blotchy in places - this is the worst area. I'm guessing the problem is surface contamination; does that sound right?

What to do next - any alternative to stripping it all right back to bare plastic? Last time, after the last coat of primer, before the top coat I flattened it off with 1200-grit wet-and-dry and rinsed it down with water - was that right? (it was definitely fully dry before I started lupinning...)

I was advised not to use primer just give it a rub down to provide a key for the paint(it was water based from RS Motorbike Paints). They told me to use several "dusting"coats,allowing it to dry well inbetween. Never had no problems. Was it cold where you sprayed?
I'd be inclined to carefully rub the blemishes down and give another coat or two,see how it goes.
Are you going to lacquer them?

Same paint, same source (thanks to your belly pan post!). Actually RS advised me to use 2 mist coats of etcher, then flat it gently, followed by grey primer.
No, wasn't a cold day; yes I'll be laquering assuming I ever manage to get that far!.

Reckon I'll be following your advice in the absence of any alternative tips - if I can manage to get away without having to order any more of that lupin paint (what is it, liquid gold?) I'll be happy...

Today I was reminded why I didn’t paint my panniers blue. Or any other colour.

In a moment of Brain Fade after a 300+ mile day I pressed the Release button instead of the Open button.

Wham Bang Thank You Ma’am!

One loaded pannier hit the (concrete) deck.

Oops!

Popped it back on and we’ll be good to go tomorrow.

There is a product called paint prep that you should do the final wipe down with prior to shooting paint, that should help with the "fish eyes" you are seeing in your paint.
