Scratches

[Guest]

Having a little trouble with my SD wet black. I knocked out a wrench the other day and threw it in my pocket to bring with me. I got where I was going a couple of hours later and it had a ton of fine scratches on it. I had nothing in my pocket - except lint. Today I thought I'd test my cure time. Used a thin metal tag(the ones I got off Ebay) - shot and cured. Oven reached temp, gave it a couple of minutes since they were really thin(checked with IR too), cured one batch for 12mins a second for 15. Both scratched when rubbed with my sweatshirt. I put one of them back in the oven for another 25 minutes and the still scratch, not as much though. Anyone have any thoughts?

Re: Scratches

Have you tried throwing it back in the oven for 30 minutes from room temperature? It's a shot in the dark but that has worked for me before with Bumper Black. Then I also let it cool down in the oven for about an hour with the small door open and don't touch it for a few hours. I get pretty good results that way.

Re: Scratches

I have had the same problem with wet black.

HD - near 400. My oven has trouble with the temp control. Seems it always runs way hot. I think I may invest in a PID for it. I'll try the scuff test again tomorrow.

Juan - yes. I let it cool, it scratched, threw it into a 400 oven for 25 more mins. The result was better but not perfect.

These things are way thin - how long can it take to reach temp?? I'm throwing the wrench back in now. I figure I'll leave it for 30 or son and try to scuff tomorrow.

I can't imagine they take very long, even some of the intake and intercooler pipes I've done take a matter of 5 minutes to reach 400 if I throw them in there at room temperature (oven at 400). The only stuff that takes some time is thick cast parts like some wheels and valve covers.

Good luck man, let us know if you figure out how to prevent it, I would like to know as well.

Re: Scratches

I just read about a guy who had his wheels done and had scratches from washing them.He used a wax overtop of the PC!Does that harm the PC at all?

Re: Scratches

If a part is underbaked it will scratch, powder will nick and you will lose gloss retention...that is why we offer mainly overbake resistant powders

Re: Scratches

You beat into my head enough" takes 24 hrs for a part to fully cure" and those 350 lb beams we coat are handle with kids gloves until they are fully cured. Once they have set our customer loads them without the use of fork condoms.

Re: Scratches

A part is fine to handle after she has cooled down (unless you are into the pain) but the full cure is complete after 24 hours...

and maybe they just don't have one's that are big enough

Re: Scratches

This is something we've started getting into the habit of doing over the last couple of months. We don't handle ANYTHING until the next day, period. No sanding off letters on valve covers, packaging or shipping parts, even touching the surface with our hands, until the part has sat around for at least a day. We just throw it in the office and forget about it, or at least try to most of the time :P

Re: Scratches

Whenever you have something with a extremely smooth finish on it it will show scratches even from running a cloth or fingers over it (they show worse on the darker colors).........if you take a highly polished piece of aluminum and rub a cloth or your fingers over it you will see fine scratches in it and the aluminum is harder than any PC.

After every show we do, we have to wax and wipe down all of our display pieces from getting handled so much during the show (alot of times it is dusty which makes it worse) I have a tube of Meguiar's scratch X http://www.meguiarsdirect.com/detail/MEG+G10307 that I carry with me and it works great. I had read awhile back that someone always waxes their pieces before they send them out........I just let the customer know that they can treat/take care of the PC finish just as if it was paint.

One thing I will add is I have noticed that the fine scratching is much less noticable on the pieces I have the Diamond Clear Acrylic on

You're experiencing the scratches? I do too and keep pulling my hair out (whats left, okay three stands) because I can't get it to stop. I recure let set all night. I have some stuff I know I over cured because the clear dulled and it still gets the fine scratches if you rub them with a cloth. Is the pc the same as paint when it comes to this? I thought it wasn't suppose to.

As far as the ultra fine scratches on a glass smooth finish, yes it is about the same as paint....try throwing a coat of wax on it and it will be 100% better.

Re: Scratches

There was another post about those fine scratches. Someone mentioned that hitting it real quick with a torch seemed to make them disappear. I decided to try that tonight with some sample panels of gloss and mirror black that have been banging around and on the table at shows for a couple of years. They were looking so bad I didn't show them any more. By the way, these are PBTP sample panels, not my own...so I ASSUME (I know...never do that) that they were fully cured. I fired up the torch, one quick pass, and holy SH**! All the scratches were gone! Well, after making all the samples on my desk look like new again, I am convinced that (on some powders at least), it is an excellent solution. I do agree that once cured, a coat of quality wax will help in preventing further scratching.

Re: Scratches

I got the same problem today when i took some samples to my Local HD shop to drop off some samples. I had the Dirby cover in Candy Black the owner took his shirt sleeve to wipe some dust off and it scratched the surface he wasnt to sure about it. But I told him it would remove with wax and that he didnt hurt it. I almost wanted to cry cause this Is my 1st attemp at displaying my work. I re-assured him and i got to display The Cover and my sample pieces in,Mirror Black,20% Black,Transparent Blue/Red over real chrome,S&S Wrinkle Black,Silver Explosion. He said he gave out a few of my cards already. Might ecen have a Tag Plate soon as next week.

So do i add on a extra day to the turn around tim efor curing or do i put some Mothers Carnuba Wax after its completely cooled and how much for the wax job?
