i got a front fender in excellent shape for my cougar. no rust and fitment is perfect. but my car is black and the fender is grey. can I lightly sand off the clear coat and shoot it with urethane base coat and clear coat? the fender has the original factory paint. not sure what ford was using back then and if it will react with the urethane. thanks
400- 600 wet sand, if you hit steel just prime it. should be fine.
thanks. if i should hit bare metal, what type of primer should i use? how much should the primer overlap the surrounding paint? also wet sand the primer area with 400- 600?
If your gonna use urethane paint you need urethane primer. If not you'll have problems. Also I would recommend self etching primer on bare metal then most like a top coat of your reg primer before paint but check the label to find out that brand's way. If your gonna primer might as well just hit the whole fender. And I use 400 between coats of primer and then 600 before paint. And yes wet sand the primer area before paint I always soak my paper 30min to insure its nice and soft.
Hope that helps

P.s if you shot it right the first time you would be eating it and wouldn't have to reshoot it! LOL
Careful, etch primers don't react well with some paints. an epoxy would be a safer bet. lacquer spray can primer can also have bad reactions too.
You should also use what the paint mfg. recommends as far as sealing or priming.
You also just need to prime any bare metal. if it's small, you could just use a small roller to prime the spot and sand it out flat. saves a lot of gun cleanup
Some of the best painters have problems from time to time. ;)
ipsd - maybe 'reshoot' was the wrong terminology on my part. the last time the panel was 'shot' was at the factory.
hello- i did the base coat and clear. came out pretty good- if i do say so. no runs. but ever so slight orange peel in one portion of the clear. can i use rubbing compound or 1500+ grit wet sand paper on the clear? is rubbing compound a thing of the past only used on old school laquer paint jobs?
Wet sand it with 2000, and then buff it. use a polishing compound and a then a machine glaze
thanks for all the advice. this group of people and this site rocks!
Hi. my painting confidence is boosted since i successfully accomplished the fender. another question on shooting another panel: On my hood and roof, in some spots, the clear coat is sun damaged. is it worth it to carefully sand off the existing clear from the whole panel and just shoot with new clear then wet sand and buff? or am i better off preparing the surface then hitting it with brand new color and clear? it is solid black and the existing base coat doesn't appear to be peeling or cracking.
you will need to reshoot the base too once the paper hits it. make sure you sand all the flaking clear off
I just noticed this thread for the first time... I've learned from working at a body shop that black always matches black... its the only color that does. So if you're able to successfully paint that fender then, with some buffing, your fender should match your car.
Daminc- what happens if i get a run or a bee lands in my base coat? that didn't happen when i did the fender. but i know murphy is going to show up when i do the roof and/or hood. I figured if and when it happens I would carefully sand it out and then clear (?). but you mentioned in your last post that 'once the paper hits the basecoat' i would need to shoot new base coat. Thats how i interpreted it.
if you get a run you need to sand it out and hit that area again with base, but you don't need to sand the entire panel, just where you problem is and shoot the base and either blend it in or redo the panel. Usually when you sand base it gets lighter in color and dull looking compared to a non sanded area.
Where are you painting this? in a garage?
the window where bugs will get in the base is very short. A few, you can just pick out with tweezers. but if you have that many bugs to worry about, then mabe you shouldn't be spraying it there. ;)
Honestly, water in the air lines is usually more of a problem
Are you making a spray booth in your garage?
yes. i'm painting in a garage. while i'm paintig i have to leave the door open. thats why i was concerned about the possibility of having a bug land in it. i used a cheap inline filter last time. the kind that come like 3 or 4 in a package. is that sufficient? or did i get lucky?
I painted my car in my garage and it turned out great. This was my first car I ever painted too. I had my first car painted at Macco and I figured on my second car I could do just as good or better then them and turns out I was correct. :D
filters really depend on size, how much your compressor runs and heats up, and the surrounding outdoor temp and humidity.
a good way to help stop moisture from traveling to the gun, is to put on an additional 20-50 feet of air hose. I got an extra 50 on mine that I have coiled and set higher then the compressor height so moisture can collect and drip back into the compressor and water collector. I also have an in line water collector at the gun.
Mabe you can use some furnace filters and an old box fan to vent the fumes and overspray, then you don't have to keep the garage door totally open, and the filters will keep bugs and debris from blowing in. if you have a window for some fresh air to get in the garage, you can put another filter on that too.
I've painted many cars and truck in my garage just using enough fans, filters and don't skimp on the respirator.
the chemical cartridges must be changed after it's life is up, or it won't work. a supplied air system should really be used for bc/cc, but your not doing this every day. the chemical cartridges usually say how many hrs they're good for on the package.
I also had my car painted by a body shop when I was 18. it was a good paint job, but I didn't want to spend that kind of money again, so I learned that it really wasn't hard to get a great paint job and do it myself.
and adding to the clearcoat question yesterday. once the cc starts breaking down it needs to be sanded down to a point where the new paint will adhere and not lift or peel from it. and remember it's sometimes tough to know what a person is up against as far as the condition of your existing paint, without seeing it in person. but the rule of thumb is..... you want to do it right the first time, so if the paint looks bad enough to need a new paint job, then it will probably need the usual steps to repaint the panel. If you were feeling adventurous, and wanted to try to wetsand the clear and try to reclear it, that would be up to you. But if your going throught the trouble to sand it down and reclear it, then an extra step of base coat wouldn't be any more work except for reloading the gun and cleaning it out from the color coat. ;)
one thing i am still a little unclear on. what primer to use for the following issue. while sanding the clear off the roof this morning i came accross a ding and part of it was down to the metal and had slight rust. I removed the paint from the ding and a couple inches around the ding. I got rid of the rust. i'm about apply filler and sand the area smooth. can i use urethane primer in the affected area for this repair? I have a can of urethane primer sealer and also a high build urethane primer. how much should i overlap the existing paint?
you need to only prime bare metal or filler. There's no real set overlap. just as long as it covers. or you can seal the whole thing, but it's not necessary to do that.
so i can put the urethane primer on the bare metal and filler? the affected area is all sanded smooth now.
shoot away
Any updates on this thread, any "after" pics?
Hi- wasn't ignoring you FLSTCI71. i didn't see your post until today. i started the roof and hood quite a while ago and was waiting to get my hands on a good size compressor so i can properly shoot the BC & CC. in the meantime, some punk scratched the F word into my hood in a HUGE way while i was at walmart. i temporarily fixed that and I solved my compressor problem. when it gets a little warmer here in NJ i am going to tackle the job and i'll have before and after pics. thanks
Holy ! I would be so mad... I AM so mad (for you)! I hate punk vandals!
I am half afraid to get my XR-7 out of storage. Nobody ever does anything to my ugly cars, but the nice ones are always targets.
I would be pissed off to, Tough enough to work on stuff and have someone mess with it. Don't try to spray bb +cc in the weather were having now in the NE. Unless your in a clean heated shop.
