deeep water spots in paint

[crumbut]

Im gonna keep diging deeper (wet sand, compound and buff) if i dig too deep ill have no choice but to paint it ;) either way the spots will get out at some point

Got another brand compound to try.. maybe the ultimate by mguires just isnt agressive enough.

Ok.. going at it again.. new buffer.. now stronger buffer.. kinda cutting them but not completly. I have a few questions about rubbing compound.. cuz maybe im doing it wrong.
I stop and clean my wool pad when it gets gumed up with wax and the pad is pulling color with it each time.. is it normal to pull color? I mean once i wipe it off the car its shiny and not tacky.. should i let the pad stay gumed up? Or maybeinot need to make several runs back over it with a clean wool.. maybe im just not getting through all the wax?? But its squeaky as i wipe off the residue.
Im afraid im gonna go oops theres the primer!

Well when you used the mineral spirits you stripped off all the wax and yes clean the pad and if you go oops you went to far like I said wipe it with lacquar thinner it will haze then buff with wool pad it will leave swirl marks if you were. Closer is come try what I could

You likely have chemical staining going on, and its permeated the topcoat... If it was poor paint to begin with, it is likely a refinish situation. Something has reacted to the clearcoat and stained it. Clear is supposed to be a thermoset material, but while its curing (which takes weeks/months) it is sensitive to acids and alkali's let alone other chemical based cleaners... I have seen this before, and is likely what you are experiencing. Once it is imbedded in the topcoat, it's there for good. If wetsanding and polishing isn't taking it out, it's not coming out...

Get a pro to look at it, as mentioned above... a paint rep, not your neighbour that has painted 1 car...lol

Good luck, it's a heartbreak...

Clear coat

If you are getting color on your pad, you went right through the clear! If the car doesn't have clear on it, you're still o.k. for the time being. Be careful from here on out! If they don't come out, you know what has to be done! Good luck!

I don't think it was ever stated that this was a clearcoat paint job, I understood it to be a regular enamel covering. It doesn't even sound like it's acrylic.

My friend had the same problem with his red '69 road runner years ago, and nothing we tried would fix it.

Thanks Guys

Yeah I have relaxed my efforts for now. Id say a paint job is in order but $$ is the draw back for now. I dont think it ever had a clear coat to be honest but was unsure. Im not a paint expert by any stretch. The car was repainted a few years ago before I got it. I had thought It had little to no bondo in the car but Ive noticed some clues in places I didnt see before whoever painted the car did an awful job and Im thinking maybe they painted over something and thats what Im finding LOL the deeper I dig the more thats there!! So if I ever get the time and money Ill get down and dirty till I hit some factory primer and bondo. The car does shine up nicely but those damn spots!! I might rattle can the top of the car with black just to be done with them temporarily.

Ive learned quite a bit with this thread, Thanks to all of You pitching ideas and advise. Thank You

Not trying to change what your doing but if you have the equipment needed, I think i would be tempted to get some Acrylic Enamel and sand it down and paint it. MHO.. You say you do it and then comes right back...

I have over fifty years in the body and paint business and I would agree with the folks who said it's time for a repaint. More than likely it was not refinished in base/clear when it was repainted. Most likely it was done in a single stage acrylic enamel.
Those paints were very porous and susceptible to hard water stains,acid rain,bird droppings etc. All the resto's I do for folks the car is taken down to the bare metal which is the best way to go. I would,at the very least.D/A the finish down to the original paint and apply a good urethane primer,block it,and reapply more primer if needed..then be sure to apply a good grade urethane non-sand sealer just before you shoot your color coats..weather it be base/clear or another acrylic enamel. The sealer will give you a much better finished product with minimal die-back and better color retention. Substrates greatly affect the finished product...that's why I prefeer to strip to bare metal. Sorry this was so long winded...but hope it helps!
