Over the past year, my O/S mirror cover has developed a bad case of pimples. After ten years in a bodyshop, my guess is that somebody has been there before, and it hadn't been prepped properly, possibly still wet.
Anyway, it got to a point where it annoyed me way too much, so I used the opportunity to test out the Paints4u milano red kit (primer, paint, clear). Thought others might like to use this to help decide if it's worth it.
As I no longer have access to a bodyshop, this was carried out with basic Amazon purchases.....even slow degreaser.
Wet flatted the entire mirror cover upper with 240......in the kitchen sink, don't know how I got away with that! Grey scotchbrite and washing up liquid was used to clean and scuff the remainder. The inside of the cover was also cleaned to lower the risk of contamination.
Drying was carried out with a microfibre cloth and a hairdryer set to 'mouth of hell' mode!
As aerosol primers go, it's not bad. Good spread on the nozzle, decent coverage from two coats, and I was flatting it back within the hour.
Again, a pretty decent nozzle, making the process simple enough. The paint itself is fairly thick, so you can lay it on with confidence after the first light tack-coat. The last pro-grade paint I used in the bodyshop was DuPont Cromax (water based), and I know that the colour chips sent from them contain 10 (probably more now) variants of milano red, so I knew colour matching a specific car would be tricky, which is why I chose to test it on the mirror. The match is pretty good on mine. In the shade it's lovely. Reds vary in numerous directions, but the main ones are orange (bright), brown (dirty, older reds), magenta (darker, more cherry reds). This paint errs on the orange end of the scale when in full sunlight, so I'd probably not use it for an obvious panel to panel job.
Here is the biggest downside of aerosol paintjobs! Again, the nozzle is decent, but for the love of god, keep the can upright and move the target item, or it will
spit. It's a very thick clearcoat, but as always, it flashes off so fast that it doesn't have a chance to really flow itself to a smooth finish, so some orange peel will occur. I actually cured it overnight, flatted it back with 1200 this morning, and went for a more confident coat, but the results were the same. Maybe flatting with 3000 and then machine polishing would work, but it would take a brave person to try polishing aerosol clear on a plastic panel, expecting it not to tear off!
Worth it for a small job that isn't a panel to panel? Yes, might as well if you're bored and have some free time. Worth it for a larger more obvious panel? Hell no!
