Not going well for me im getting a lot of roller marks, orange peel and patches of shine and then patches of matt. Ive been thinning 10% with mineral spirits (Disolvente here in Spain) and also tried increasing the amount of thinner and tried applying very little at once and a lot with similar results. Anyone got any ideas from the pics and description, any help very much appreciated;
Are you using the white high density "professional" rollers? If so you might try up-ing your mineral spirits ratio to 20% or maybe even 30%. This weekend I brushed some paint straight from the can on the panel behind my tailights and it looks like $%#*, it's way to thick. No biggie there cause you'll never see it anyway, but when I'm rollering my other panels with the 20% mix it lays super smooth. So smooth in fact, that I've done away with all but 1200 and 2000 grit for my wetsands. Anything else is to harsh for the amount of peel I need to remove. BTW what kind of paint is that?

I totally agree re the amount of dust that wetsanding doesn't create. When I dry sanded between coats, it was more like a wipe to remove little imperfections. And Steve C - I think you could go the satin route and then polish it up to a gloss, but I don't think it would be any easier than it would be to go full gloss anyway. And I'm not sure how glossy the final result would be vs a full-gloss job.

OK - did a test fender over the weekend.
I was hitting some of the nooks and crannies with a spray bomb, and it became real clear to me how much effort would be required to get a nice quality finish rolling gloss over the whole car. Maybe I'm too much of a perfectionist, but I think I would end up spending the rest of the summer rolling, sanding, polishing, over and over.
Aussie's car looks great, but I probably have at least twice the surface area to deal with on my Charger.
So I'm going Satin, at least for now. I used Rustoleum, thinned about 25% (give or take) with 100% mineral spirits. It was pretty watery.
My first section was way too thick (I could no longer see the previous red color under the new black). And MAN it was running like crazy. I used a second clean roller to re-work the entire panel, spreading the heavy coat in the first area around the rest of the panel.
I think I'll back down on the thinner a bit for my next coat. Or, it sounds like the mixed paint in the can will thicken up a bit by the next time I get back to it.

test on an old hood, i can't stress this enough, you have to learn the paint, process ect..... I've sprayed the paint before, using a HVLP gun, and it flowed and sprayed perfectly, actually the nicest paint i've ever sprayed, and the workability was incredible. If you got runs, you for sure put too much paint, or thinned it too much. Have you painted before? Don't stress too much, let it dry a day and wetsand with 600-800, it will go quick. I could wetsand that car by hand in about 3-4 hours regardless of how much peel there is, and runs. If you shoot it right, you should wetsand that car in less than 1 hour. Don't wait too long for it to dry, it will be harder to wetsand.

What brand of paint are you using ?
And is the mineral spirits (Disolvente in Spain) a 100% pure mineral spirit or is it mineral spirit mixed with other thinner type solvents ?
How many coats of paint is that in the picture ?
Its brightside im not sure what disolvente is its the normal thing used to thin paint I used the same stuff to thin the paint I spray painted last year.
Thats about 3/4 coats and despite wetsanding to supersmooth between this is what it looks like. I am using the highest density rollers Ive found in my local paint shops, maybe thats not enough....?? Will wetsand down tomorrow and try to paint another coat but 30% thinned.
I left it 24 hours between coat and its quite hot here.

The hotter it is, the thinner your gonna want your paint, it may be that the surface of your coats is curing before you finish working it causing the peel.

"The trick is to take as little as possible on the roller and spread it on like you are the cheapest guy in the world and you are trying to stretch out every drop of paint to its maximum."
LOL, Too Funny!! I was just laughing at myself thinking the exact same thing as I was rolling my taillight panels yesterday.

rustoleum sunburst yellow + mineral spirits after setting gun right and presure on gun 46psi it came out good still have few runs, but thats my fault still cant get used to hvlp gun its putting much more paint then my old gun, oh yeah for me, mix 6-3 (6 part of paint to 3 part of mineral spirits) work out the best. make sure u use pressure regulator on gun, without it set presure around 10 psi higher on compresor, depends how long your pressure hose is

20 feet... but im up for getting a new hose... it's leaky once in a while. Also- for some reason my compressor fills up and does not turn off automatically... any idea how i can fix that? Im going to get some satin black tomorrow and test it on an old fender. Im painting in a garage- as far as ventilation and cleanliness... I assume I have to take everything out and leave the garage door slightly open? Im new at this... sorry- Thanks for all! I love this thread

One of the best tips shared in the thread by a previous spray painter was to have a couple of those high density 4 inch foam rollers nearby while spraying. IF you spot a run... you can quickly hit them with a clean roller ( not loaded up ) and work the run out. Then it will self-level along with the sprayed on paint and you won't be able to detect where the run occured.
It's more of a problem fixing runs after the paint has cured. So by whacking runs right away with a roller... your fix on the fly will blend right in and be undetectable.
That is one of the benefits of this paint method - whether rolling or spraying... in that the curing time of the paint allows you enough time to work out the problems on the fly...

Thanks for the help mark Ive got through 2 cans of brightside now so that probably a sign of me laying it on too thick do i need to go back to square one or to a point where everything is uniformly smooth?
Since were only talking about thinning 10% could I apply it without thinning, reason is it took a couple of weeks to get the brightside since I had to import 6 750ml cans from England and I fear the spanish may not have the #333?
