I just finished up a quarter panel blend repair with ppg bc/cc but unfortunately the color they mixed up wasnt a close enough match and you can definatley spot the repaired section. I went and had the paint remixed and now it is a perfect match but my question is how long should I wait and how should I go about reshooting the blend area without causing a bad outcome.
thanks guys

 

2 days should be good if you used the right reducers and hardeners.

 

thanks, I had an issue with fresh clear reacting to new basecoat before thats y I asked. Would I be safe just wetsanding the sheen off the clear then basing over that?

 

ttt

 

I would wait at least a week to make sure all the solvents have completely risin out of the substrate material. Then just scuff and reshoot. I have done it in less time but on occasion have had a few problems of hazing. The more time you give it the better. Actually most shops recommend 30 days before waxing a new paint job because of the solvent issue.

 

Ive never had a problem with reshooting the same day as long as it has been baked or if excelerator has been used, if it hasnt I usually wait a day. But then again I dont like/use PPG and I rarely have color matching issues with the paint I use.

 

I would wait atleast a week so the clear doesnt start to ring on you. Now are you going to blend into the door? since the old color was off and now it may look even worse if you just try and do the same blend as before?

 

a week seems to be the general response. The original blend is about even with the back of the wheel arch so Im gonna bring it a lil farther forward. There wouldnt have been a paint match issue but I was using paint left over from my last civic, guess it had a lil less sunfade

 

A week LOL for what? Im taking it no one in this thread is a painter who works in a shop. Go tell any painter to wait a week to respray a bad color match and they'll laugh in your face.

 

Ya a shop thats only worried about the bottom line $$$ and just wants it out the door maybe. Not a quality shop

 

Im a painter and id rather tell a customer that there car will not be done for another week because of complications rather than have them come back a couple months down the road saying the paint is dying back because of the solvents being trapped in do the job right the first time rather than do it again over n over and get a bad rep

 

Glad you said it. Because we both know thats the kind of things that will happen if you rush a job

 

If your a true painter and the paint is mixed and sprayed correctly with the correct flash time then there is absolutely NO reason to wait a week.
Dye back,blistering, solvent pop, whatever, if you have to wait a week your doing something wrong. Either your mix ratios/viscosity is off, donig something wrong when applying the paint(incorrect flash time), or something in between.
If a car has a bad blend, I bake it, take it out and let it cool and prep the panel again. Rememeber, once you sand through the clear whatever solvent is left will be released.
Wet Sand the color area to original color, scuff the clear portion of the clear panel, prep/clean it for paint, and in the booth it goes.

 

Again I never had an unhappy customer and have never had a problem respraying a panel the same or next day.
Quality is top notch and my work speeks for itself so lets not go there.

 

I will wait a week, I dont have an oven to bake it in so thats out of the question.
