	So since everything is locked down, I thought I’d have a go at painting the spare wings for the Astravan I had got hold of some colour matched aerosols, primer and lacquer just before lockdown. So I prepped the 2 wings, primed them ok but when I painted I got fish eyes. I thought it was the degreaser I was using (brake cleaner, as I hadn’t got anything else beforehand) I got some panel wipe from a mate, and tried again and still got fisheyes. The van isn’t perfect, so I carried on and sprayed over and seem to have got away with it (I will repair the original wings, get them sprayed properly and refit.. so if the paint isn’t going to last etc I’m not too worried) But would be nice to know what I did wrong for the future Tried again today, and tried spraying vertically, with similar problems I wondered if my ‘spray booth’ didn’t have enough ventilation as everything seemed to take a while to flash off. Obviously I haven’t got any facilities, but any tips for doing it better with what I’ve got would be great The other thing, the more important to me, is that I’ve carried on, painted and lacquered and am not too worried about the faults (they’ll blend in) But would be nice to get a bit of shine, so they blend in a bit better I’ve got some fine wet and dry, or could fit and use polishing machine... but don’t know how long to leave before touching or what to do really Thanks in advance

	John - If you are using panel wipe and you still have issues you have to look at what you applying it with & how - unless you have gloves on you will still spread grease off your hands / skin on to the panel - you should use a clean / unused / lint free cloth or a dedicated panel wipe pad - then check your surroundings you could even be getting contamination from the cardboard that the panels are up against - the whole area needs to be has clean as possible - any bits of oily engine / car parts / drive train will not help you in the slightest - shine wise it looks like the lacquer has been applied too light / dry its needs to go on heavier in slower passes of the can - if you have enough lacquer I would be tempted to just go over the panels again with a fine scotch brite and reapply the lacquer but you need to see / watch it going on you should be more or less able to see instant shine as you apply it - I wouldn't bother attempting to achive a finish with what you have applied to date - just bug me if want more info or give me a call - the phone is always on - Chris

	Thanks, Only paints I’ve used in recent history trying to paint a large-ish area have been combi-colour or Montana graffiti paints which are pretty forgiving but at the expense of the finish I suppose I could have had anything blown onto the panel then to cause the contamination then.... oh well it’s all about the learning! I have another can of lacquer, so will try again tomorrow

	I don’t think I’ll be stepping on your toes any time soon Chris Been out and relacquered... now I’m looking I can see the dust etc everywhere But lacquered over the top before Lucy got home It looks shinier already, so sure it will be better..... (May be asking how to get rid of lacquer runs later on )

	Looking much better I'm far far from an expert, but here's my 2p.... Possibly gone a touch too far with the slower/heavier coats of lacquer if you're getting runs. It's a fine balance, and just one of those things that comes with practice. To get rid of runs in normal aerosol lacquer I'd first say wait 3-4 weeks for the paint to really go hard, especially the actual runs where it's thick will take a long time till it's hard enough to not mark with your finger nail. Then with a sanding block and some fine wet and dry paper and a little lightly soapy water, I'd normally go for 800, sand away the high spots of the run. Carefully as not to go too far, it's easy to go through the lacquer. You'll then need to wet sand with 1500/200 grit to take away the previous sanding marks. You'll then need to go over the whole panel with rubbing compound (scratch remover liquid/paste off the shelf form Halfords works also) to put the shine back on it, then finally polish + wax as normal. As an example, this was the finish I achieved out of the gun on my Lancia a few years ago. Note the orange peel texture and dust stick in the surface. I went over the whole car with 2000 grit under a gently running hose. You need to keep sanding till it's a smooth even finish like this. Any low spots will show up as still shiny. Then you can compound. It's a lot of work doing a whole car by hand like that I can tell you! Obviously if you've got a machine polisher there's easier ways to do it, but as lots of us have plenty of time right now, I see it as a cheap couple of days entrainment.
