Repaints and LSP?

Ok guys I have a Suburban today that had the passenger side repainted about 3-4 weeks ago. I was trying to get a consensus here as to how long you have to wait on a repaint before applying a wax and how long do you have to wait before applying a sealant. Like I said it was only the passenger side that was repainted so what would you guys do. This thing is in for full correction as the body shop didn't do a very good job so I was asked to fix it.

I have seen and read many different thoughts on LSP on a newly resprayed car and wanted to see what the consensus was here. Thanks in advance.

 

IIRC, you have to wait between 4-6 weeks before you can do anything to a repainted area.

 

OK I have another question as well. If you did apply an LSP after say 3 weeks of the respray what exactly are the adverse effects from doing so?

 

it doesnt cure properly for sure, but to what extent, my only guess is that it wont harden correctly

the gases have to escape

 

First, one really shouldn't wax over fresh paint for a few months. The most common adverse effect is tiny bubbling in the paint from the wax or sealant trapping the solvents causing it to blister. A coworker of mine had this happen to him after he had some work done to his car. He blamed it on bad prep work but but was asked by the bodyshop if he had waxed it and was later told that is what caused it.

 

I would see more of an issue with using a sealant, than a wax. Simply because I'm under the impression that the wax lets the paint "breathe". but this is just a thought, not to be taken as advice.

 

JL, Megs sells body shop safe glazes you can apply for temporary protection. Other than that, I wouldnt apply anything.

 

To me that was just a way out for the the bodyshop. I would agree and say it was bad prep work.

JL-most of the time bodyshops bake the paint in a booth. I would have no problem using a wax over the vehicle you are working on. My buddy that has the cusom paint shop, after wetsanding and buffing the vehicles we would wax them and no one ever had any problems.
If the vehicle wasn't painted in a booth and baked I still do not see a problem with using wax since it breathes. I would not use a sealant if it has not been baked. Also I wouldn't trust a sealant even if it was baked because I have never tried it and do not want to tell you something that I can not confirm the outcome of.

 

JL..My belief is that only glaze should be applied at this point. I would go ahead and correct and seal the rest of the vehicle for now, but the painted areas would only get glazed (and not one with protection). I would have the owner wait for the spring. Your reputation as a detailer is more important...besides, he brought it to you in the first place, so he should respect your opionion to have him wait. Like in the example of the paint job where the guy waxed it and subsequently blamed the paint shop instead of owning his own stupidity, this owner would or could blame you if the paint bubbles in the future. I would wait to seal it until the spring. You do such good work: don't risk it with a customer's car.

 

That defintely wasn't the case. It was at the dealership that he worked for.

 

Glazing is the best choice since it allows the paint to breathe without blocking the pores.

 

How does working for that dealership change the possibility of them not prepping the vehicle correctly. I had a hood painted on my civic years ago by my dealership and waxed right afterwards with no ill effects.

 

Trust me. Not this dealership. They won't use it as an excuse. It has been documented for years that you shouldn't put any layers of protectant over a freshly painted surface......whether it's been baked or not.

RE: Don't wax after a respray

 

Great, I feel otherwise and have done it differently for years without any problems. Plus the link you posted goes to a car cleaning thread so of course they are going to be cautious on what they tell you to do with their product on paint. Seeing this being done for well over 20 years and doing it myself without any ill effects I will continue to wax after a repaint if ever done to one of my vehicles. Plus you are telling me that the dealership has never made a mistake in prep work, I doubt that.

 

after i had my door repainted the body shop said it was fine to wax .and if i polish use body shop polishes. breathable carnuaba waxes. not sealents.

 

Call the body shop and ask them. Thats the best way to figure out for sure. Im sure there are differences between shops.

 

That's your choice. However, if there wasn't a concern then it wouldn't be talked about for several years.

 

You have to take in who is talking about it, who on this thread has actually worked with paint? Then they are just giving out random info, this is something else to think about.

 

Never said that. However, what I will say is if it was bad prep work the paint would be peeling......especially on a plastic bumper since it is the most vulnerable. The paint blistered (tiny specs) and finally cured to that form.

 

after i picked up my truck from the body shop. the owner knowing im crazy about cleaning my truck gave me a bottle of his body shop quick detailer. its pink and smells like CHERRYS!!!. and said use this for a couple weeks when you wash your truck. so i said ok no prob..
