I applied 4 coats of clear, waiting 10 minutes in between, but it came out matte looking and it is not smooth. Is it possible to fix this?

  • This has been asked on here before. Short answer humidity and so many other factors are at play... – Solar Mike Aug 28 '20 at 14:38
  • @SolarMike so is it possible to fix this, if so, how? – Giancarlo Aug 28 '20 at 14:40

  • How does it feel to the touch? Trying to get an idea how much of the dullness is down to humidity and how much is down to the texture of the finish. – motosubatsu Aug 28 '20 at 14:52
  • @motosubatsu it feels a little rough – Giancarlo Aug 28 '20 at 14:55

    Hmm.. yeah it did look it. Without seeing it in the metal to be sure that might be the root cause (it doesn't have quite the milkiness I'd expect if it was down to pure humidity), I'd say it's worth a go to wet sand (probably ~1200 grit) try machine polishing up with a gentle cutting compound. – motosubatsu Aug 28 '20 at 14:57
  • @motosubatsu should I wet sand with 1200 alone or try 2000 afterwards? – Giancarlo Aug 28 '20 at 15:02

    Sort of depends how it feels after the 1200, if it is dull but smooth you can go straight to mop-ing and work through a couple of the gentler compounds, but if it's still a little rough a follow up with 2000 isn't a bad idea before moving on to the polish/buff. – motosubatsu Aug 28 '20 at 15:09
  • On the other hand if it still feels really rough after the 1200 it might be time to roll up the sleeves and get the 600 out - in which case you'd probably go 600->15000->polisher – motosubatsu Aug 28 '20 at 15:10
  • @motosubatsu thanks for the tip, although I know very little about polishing, what compound should I choose after wet sanding? There are so many different things, is polishing paste the same thing as a scratch remover? – Giancarlo Aug 28 '20 at 15:15

    What you're looking for is something often called a "cutting compound" - many manufacturers will grade them in effectively a "grit" like sand paper is, and the principle is the same as with sanding, start with a lower grit and move up to a higher one for finishing. – motosubatsu Aug 28 '20 at 15:40

    If you haven't got a suitable machine polisher you'll need to look for something that can be applied by hand Megs Ultimate Compound is a great one for novices, although it might be lacking in outright cutting power for this job, although you could compensate with an additional wet sand with a super high grit (say 2500-3000) if required. It's a great all-in-one since you generally don't need a separate finishing polish step. – motosubatsu Aug 28 '20 at 15:41
  • @motosubatsu, thanks a lot for the help, I'm gonna go to a professional body shop tomorrow and see what they have to say – Giancarlo Aug 28 '20 at 15:47
  • @motosubatsu well damn... they tried wet sanding and polishing and the clear coat is just peeling off, they're going to repaint it, fortunately, it's just 120 euros – Giancarlo Aug 29 '20 at 08:20
  • Peeling off? Did you let the clear coat cure a couple a days? Or a least a week and then try wet sanding? – Christopher Miyagi Feb 21 '22 at 04:16
