polishing after painting-how long to wait?

LangMan37 · 08-04-08, 10:17

Just wondering what is the consensus on how long to wait after painting to polish? I've heard a week, 30 days etc. I'm not sure if it's been CC but I got to think that it has.(I'll find this out when I go look at the vehicle). Would it make any difference in waiting time if it has been CC or not or is the waiting time the same? It's a black jeep wrangler. The paint has drips that the owner wants removed. And it was only painted in certain areas, not the whole jeep.
Thanks for the help.

you can polish when every you want
but it will be soft as it cures

NO LSP for 90 days!

ok cool but why is it necessary to wait to apply your LSP? Am I waiting for the paint to cure or what? I'm thinking I'm going to have to wet sand (2000 grit) the drips and then proceed to polish the wetsanding marks out.

Fresh paint - Polish OK?

I'd say it's as hard as it will get after a few days. Even if it isn't baked.It's the solvents that are outgassing for what some say a few months. I've gotten totally different opinions from dozens of painters. Out of the 1000's of vehicles I've seen, I've never seen a single one that had paint failure from trapped solvents from being sealed. Someone should call Mythbusters.

my evo 9 got repainted by previous owner and "just looking at the paint swirls it"
I tryed everything and just after getting a panel perfect I do an ONR wash with sheepskin and it leaves swirls.
I guess it must be due to LSP applyed to early because the paint job itself looks really good

I agree. I had my front and rear bumper repainted (grey metallic with cc). I asked the body shop when can I polish/wax it. They told me that it was heat baked and I could polish/wax right away. A day later I polished and waxed that has been over 1,5 yrs ago and there are no problems with the paint. My car gets QD daily and waxed every 2 weeks, shows how anal I am about my ride.

I'm all for somebody doing controlled tests of this stuff with regard to LSPing, but I can state with zero ambiguity that I've experienced the months-long hardening process *with baked paint* first hand on numerous occasions.

Two examples that stick in my mind:

I've had RM brand b/c that was too soft for Meg's #80 for over three weeks (incredible to see such hazing from the initial bite of that mild product!), but was too *hard* for the same #80 a couple of months later. This was the most dramatic example of the lengthy hardening that I've ever encountered.

On the S8 following its deer-incident repairs, I worked on it on-and-off over the course of four months and was able to carefully observe how the paint hardened. During that time, I had to gradually ramp up the aggressiveness of my products/process as stuff that was easy to correct with the PC after a few weeks required the rotary (and aggressive pads/products) a few months later. This was with Spiess Hecker paint. Its hardness in early spring was completely different from its hardness at the end of summer.

It could be due to a cheap soft clear coat.

From the factory, you can polish/wax right away since they cure right away from the extreme heat & lack of interior/other components. Bodyshop, ask the painter who is hopefully educated to know the proper cure time. 90-120 Days before any paint or glaze solvent products should be used. You can use a "pure" sealant such as Optimum Car Wax & Zaino sealants

These both sound like a paint hardener issues, where the painter didn't mix his hardener right. Rydawg does tons of work for a shop that uses Spies Hecker and their fresh clear is super hard.

Accumulator - I know you have a relationship with your body shop/painter. Did you ever discuss these softness issues with them?
