Got a clearcoat paint question
I've sanded, primed and base coated several quarter sized chips on the underside of the doors. I was going to clear coat them last night but ran into a snag and couldn't get to it till tonight.
Should I sand the base coated areas with 1200 or 1500 grit before applying the clear coat? I was thinking that the clear should be applied fairly quickly after the last base coat but I 'm not sure. I don't have any idea how to deal with this base/clear stuff. My knowledge is from 20 years ago.
How should I proceed?
I'm using PPG products.
thanks

Re: Got a clearcoat paint question (DavidR)
I have touched up a few spots doing the same thing. I sanded the base
coat with a scothbrite pad-grey color. and then applied the clear. {ppg}
In the literature I have read it isn't recommended to sand and top with clear
but I have done it and had no problems. Normally I apply clear on top
of the base within an hour of applying the base.
Good luck :cheers:

Re: Got a clearcoat paint question (DavidR)
David, Ther is no need to sand the base if it is less than 48 hours before you clear. Since you didn't mention what color,,, IF it is a metallic color especially, DO NOT sand it, You will streak the metallic and it will show through the clear. Also do you plan on blending this clear in only the areas affected or are you clearing the whole panel. If you are clearing just the spots and blending you will need some sort of reducer to reduce the clear and melt the edges in. Usually,,,, 90 % of the time I will clear the whole panel so as to avoid the multitude of problems than can arise from a blend. Just my .02 Good Luck

Its usually 3 days beforew you would have to sand then clearcoat...as mentioned...rub it up with a scotch pad and you should do fine.

I think what you are trying to say is did you loose your window for recoat? If so just tack it off and apply your clear. Are you using PPG 2021?

Re: Got a clearcoat paint question (Daves90)
Thanks for the replys...
I will try to get it done tonight after work. I was planning on blending the clear into the upper 2/3rds of the LOWER half of the door.
I'm not sure of the PPG product numbers, I will look when I get home.
The car is Sebring Silver (I think) '96 collector edition. A hard color to match I'm told. So I guess I will not sand it, I'll hit it with some scotch brite.
I would like to get something to wipe off hand prints before I go further.
Any recommendations? Can I just use the reducer for the base color?
That's what we did 20 years ago...
thanks

Re: Got a clearcoat paint question (DavidR)
Here's what I would do at this point... considering it is CE Silver.. I would hit the entire lower section of the door with 1500...scuff it all,, including the original base you put down. Then. I would really really do your very best to blend out the next coat or 2 of base,,, wait 1hour,, then clear the entire bottom of the door.. The molding would make a good break off point.. That is most probably your best bet to get a good match and not have to attempt to blend the clear. I believe if you scuff the base with anything at all and dont recover you will see the streaks through the clear. I also would NOT wipe that door with ANYTHING wet once it has been base coated.. again,, you will at the very least streak the base coat. Keep us posted as to the result....

Re: Got a clearcoat paint question (Daves90)
I would handle the fingerprints with wax and grease cleaner not reducer. If the color is a tuff match you should hide the blend in inconspicuous areas like under the mirror or the middle of the quarter I realize you might not have wanted to spray that much base but youll need to clear beyond the panel youre working or you will likely notice the repair. I would wait a day and sand and buff the whole side to get the same finish too. Post some working pics if you can. And keep us posted good luck wth this. :cheers:
