Help with spoiler painting and sanding etc.

[imapctuk]

Right so i thought i'd spray my new spoiler today.
This is my first time doing this sort of thing so i did it off the top of my head
I sanded off the old paint using 800 grit paper from halfords and after finishing this there were some deepish scratches on the thing. Anyway, i also did some wet n dry (forgot the grit) and thought it would be okay.
Wiped it down and sprayed it with primer and it looked good until th elast coat where you could clearly see some scratches from where i've sanded.
Is the thing suppoed to be completly smooth before you prime etc? or will these be filled by the paint?

A fast reply would be greatly appreciated

needs to be perfectly smooth

don't use your hands to sand either. get a block of wood and stick the sand paper to that

Crap.
Alright, thanks man. Look like i'll have to start all over again ahaha. I just started panting as well, hoping for the best.

Any tips for getting around those ridges aswell? The ones underneath

Well i sanded it for an hour and a half and there were still a few scratches on it so i carried on anyway and im gonna hope that all goes to plan.
If not i'll take it to the Fiat body specialist around the corner.
Thanks for your help jipo

 

[jip0]

you dot need to take it to a fiat body shop just for that

 

[imapctuk]

Well it'll just be a pain in the ass otherwise. Do you think it'll look okay?
I don't really want to go out and buy more paint when a body shop could be cheaper

mate use primer filler, spray it over and sand smooth with fine grit wet and dry, or use like bodyfiller light layer over the spoiler and sand smooth again, not expensive amte

 

[imapctuk]

Sounds like a good idea man, thanks
I've just put the first layer of paint on and i really dont want to be sanding it off again. Could i put primer filler on the top of this?
Cheers

not sure mate, try if you want but im really not sure if you can over the paint

 

[imapctuk]

Ah what the hell, might as well give it a shot. I've already wasted enough time. I was hoping to have it on by tomorrow

 

[imapctuk]

Right so i went and got some filler primer and it seemed to work a fair bit, there were still a few scratches but i thought they'd get filled with the paint. After 5 layers of paint you can still see very fine scratches. I'm scared to use the lacquer now as i don't want to waste more money on it.
When sanding, i used very fine wet n dry for like 2 hours straight using a block.
Its annoying the hell out of me really. Will it look okay if i just put the damn lacquer on?

 

[imapctuk]

Well i did it anyway and it looks pretty crap
Can see the sanding scratches and the paint has the orange peel effect on it. Think i'm just gonna put it on anyway because i suppose it will look okay from a distance. No one really looks that closely at a Punto anyway.
Just letting you know that if you do get a spoiler, sand it properly in the first place and don't rush it.

mate just use p38 body filler over it and sand smooth again

Cheers for the suggestion mate but i really don't want to spend another 20-30 quid on materials and waste another weekend sanding ahaha
Just gonna give rubbing compound a shot and if not i'll try what you said in a few weeks

If you put filler over paint you end up with a halo around the filler that shines through the new paint. It will need to be rubbed back to the base material and filled from there.

Spray filler will sort out fine scratches caused by the "sanding" paper. Use ever finer wet and dry always used wet to polish out the deeper marks caused by coarse paper.

Except for large surfaces, I almost always work without a rubbing block. Yes, you risk creating finger tram-lines, but if you take care you can feel for lumps bumps and scratches as you go. Always use a block when you want a flat surface.

When it seems ok, spray ordinary primer over the area. This will show up any scratches and paint halos. Rub down again with fine paper always used wet. Paint halos have to be dug out and refilled. You can cheat if larger depth of filler is needed but don't let old paint peep out from under the filler edge.

That you for the help WhiteSei, you seem to know a fair bit about painting body parts. However, i went to Halfrauds and got some of their "rubbing compound" to see if it would help. Not expecting much i follow the instructions and somehow, that yellow tube from Halfrauds actually worked like it said it would. First time i've ever got a halfords branded product that actually worked
Anyway, here of some pictures of how well it worked

Before rubbing compound


After rubbing compound



I know its not perfect but it will do by my standards
