Repaint Question

[Samuel]

I made this Genesis Platinum Fankengrill a couple of years back and this year I noticed the black paint on the lid did not hold up as well as I would have liked. Do you all think it was due to the lack of multi coats of paint?

 

[Jeff Beitinger]

Is it possible it needed more degreasing before paint?

 

[Samuel]

Is it possible it needed more degreasing before paint?

Even though I sandblasted it?

 

[TomRc]

I’m only speculating, but an acetone wipe might’ve prevented this. Sandblasting alone doesn’t guarantee a clean surface.

 

[Steve Hoch]

I repainted a set of end caps a couple years ago that I stripped all the paint off of and then wiped down liberally with brake cleaner. I used the lid and by the end of the summer most of the paint had failed for some reason. I know I must have done something wrong but I have no idea what it was.

 

[Samuel]

Tom and Jeff points well taken, Thanks.

Just know you will never get a home rattle can finish to last as long as the factory finish which is electrostatically applied and baked on.

After all the above tips, use self etching primer first. Should help in the long run. Don't forget about proper cure times between coats.

Will a self etching primer withstand high heat?

Will a self etching primer withstand high heat?

If you get the high heat type. IDK though whether it makes any difference on aluminum. It's really meant for steel so how well it will help IDK

I do about 3 coats of Rustoleum HH Ultra on my end caps after having them blasted. I haven't had a customer complain in the last 6 years of doing rehabs. Of course, it is aluminum, so at least you don't have to worry about rust.

Yes

[Scott Smith]

Don't stress about it. Even the factory paint fails after awhile. That's why we're all repainting them.

 

[Timothy F. Lewis]

Yeah, what Scott says!

 

[Samuel]

So how should I approach this?
1.Should I use a wire wheel
2.Should I just use sandpaper?
3 or should I just clean it and go on and paint over the existing paint.

I do not want to Sand Blast it all over again. What do yall suggest is the best coarse of action?
I will be using Rustoleum High Heat Ultra Semi-Gloss Black.

 

[Bruce]

Well, I am pretty sure that a good paint thinner would strip it easily. I have one other suggestion for refinishing it if you really want something very much like the original finish. Have it powder coated with high heat stuff. I had my personal grill done with it (Another stainless platinum framed grill). It is much more durable than the Rustoleum or other grill spray paints and it wasn't all that expensive. Just too expensive to consider for rehabs.

 

[Samuel]

You know Bruce,
The guy who sandblasted it for me also does powder coating now that you mentioned it.

 

[Bruce]

Samuel: Yah, so does my sand blasting guy. Just make sure you ask him about HIGH HEAT.
Most sand blasting outfits have powder coating as their primary business. Any one searching for a sand blaster should search for powder coating. That is how I finally found the guy in my area.

 

[Samuel]

Bruce my Guy mainly does powder coating also. He does a lot of trailers, that is what he told me and there are many trailers here in Texas.
