Hey KBS,

After I aerosol zinc sprayed the caliper with two coats, followed by two coats of jet black. With the 15-30 minutes in between. 

But when i placed it on a tray to put in the oven, the contact point kind of chipped the paint off after baking. Do you have any advice? Do you think the metal tray is transferring too much heat?

For XTC Primer Aerosol and XTC Aerosol, we recommend waiting an hour between coats and always apply thin coats. These 2 recommendations will help tremendously when it comes to the paint getting incredible adhesion.

For oven temperature curing, we usually put some aluminum foil down over the rack and then put the piece on the aluminum foil. Then turn the oven on to 350F. Once the oven gets to temperature, start your timer.

Please let us know if that helps and if you have any other questions.

Hey KBS,

So more questions as I'm trying to fix the paint. After I did the oven curing temperature and all, a few days later when I try to touch up the paint again, I rubbed some denatured alcohol to clean the surface and basically all the paint was removed to the bare metal if I kept scrubbing on it.

Is the paint suppose to come off so easily after the curing and proper steps?

 

Questions:

1) Why did you rub the surface down with denatured alcohol? This is not in our directions so we are trying to understand why that was done.

2) How many hours did you wait between coats of XTC?

3) How many hours did you want before the heat cure?

4) Did you use XTC Aerosol of the non-aerosol version?

5) Did you apply normal coats of XTC or thin coats?

6) What temperature did you perform the heat cure at?

7) How long did you do the heat cure?

We are looking forward to your replies and assisting you further.

 

1) This was done after the entire heating process and cooling down and left for days. I thought it hardened and would be tough.

Then I wanted to custom paint a small portion so i naturally i cleaned the area by degreasing and thats when the paint came off.

2) I waited for a whole hour between light coats.

3) I waited 20 hours before heat treatment.

4) I used the aeresol version.

5) I did light the first coat and slightly heavier on the second.

6) 350F

7) 30 minutes

 

Is it being applied too heavy?

Going forward, please use KBS Klean when you need to clean it, KBS Klean is a powerful water based cleaner degreaser that does not leave residues. KBS Klean always works better than alcohol or solvent based cleaners.

It seems like you did everything correct so the logical explanation is that the XTC coats were simply applied too heavy. XTC always performs best when it is applied in thin coats. You can apply as many coats as you desire (1 hour between coats for XTC Aerosol) but always thin coats.

Please do thin coats and report back to us. We certainly believe you will get much better results.
