Painting Underside of ERA FIA Spare Tire Tray ?
 
Looking at painting the underside of the spare tire tray on my ERA FIA to make is less noticeable. The inside surface is smooth gel coat white, the underside a cream colored resin with glass matting.

Leaning towards using a flat (or satin) black epoxy paint with brush rather than spray paint or spray on trunk liner, so there is no issue with overspray. Also, getting spray to the sides of the tray is a bit difficult in some areas due to the body being in the way.

In hindsight, it would have been simpler for me to have ERA paint the underside of the tray before it was installed. I asked them to keep bare so I could see how it looked, figured it was easy enough to paint after the fact. The car does not have many miles on it yet and has not seen rain or mud, so the surface is still fairly clean.


Questions:

- Surface prep & cleaning ?

- Type / brand of primer ?

- Type / brand of paint ?


Suggestions and comments welcome … thanks!

It may seem kind of strange but I think I would scuff it lightly with a 3M pad, wipe it clean with Prep Sol from DuPont, prime it with Bull Dog adhesion promoter, and spray it with a couple light coats of SEM interior semi-gloss paint that is designed for hard plastic and vinyl parts. SEM semi-flat black trim paint is another possibility.

Did mine with spray on undercoating. Wasn't that tough to tape things off.

I did the same as *13*, with the Cobra on jackstands. Not too bad. Use lots of masking tape.

Put it on a lift, tape it up and spray away. I used truck bedliner spray. It is nice to have that trunk bottom panel uh, "not so obvious".

I used brush-on truck bed liner. Nice and thick and covers great. Works nice on jacks stands, etc. for a non-marking, durable surface coating.

Thanks guys for all of the suggestions. Going with black will certainly help the spare tire tray blend into the shadows under body, rather than stand out.

The truck bed liner would work well as it would be flexible and not as likely to show damage from road debris as paint will.

Planning on doing the same thing this weekend, Tim. :) I'll be using Krylon Satin Black in a rattle can and my prep will consist of a scrub with some scotchbrite and a little Simple Green. That's the plan, anyway.

Allen,

Let me know how it goes, have not had a chance to work on my car lately so it's not done. Are you going to primer it first or just go with the paint?

For preparation I was going to try the scotchbrite pad, but use alcohol for wiping it down, does simple green leave a residue? I have never used it.

Fullchat289 06-02-2012 01:09 PM

Hi, Tim.

The whole process took me about an hour this morning..used the scotchbrite (red pad) and straight Simple Green out of the spray bottle, but mine had 13K mi of road grime on it. I just sprayed the tray, dipped the scotchbrite in some water and scrubbed the surface of the tray all over like I was giving it a good clean. I then wiped the surface down with a towel and let it air dry. After that, I used some 2" wide masking tape and taped up around the aluminum boardering the tray along with the underside of the body and frame members at the rear of the tray. I then got the satin Krylon out and put three coats on. This was the result:

I don't really expect that there will be an adhesion issue as the tray surface is quite "keyed" just with the texture of the un-gel coated fiberglass. And I've not noticed any "residue" left behind after using the Simple Green. It's good stuff and reasonably inexpensive. Lowes sells gallon jugs of it for under $10. Once you start using it, you'll find all kinds of ways to get through that gallon jug. :)

On second thought, it might take you a bit longer than an hour to do it....I had this guy helping me:

Allen,

Looks pretty straight forward and nice result. Impressive assistant you have there ...;)

A few weeks ago I finally painted the spare tire tray. I went to a local auto paint store to see what they would recommend.

Used Klean Strip Prep All, Transtar 4613 Black Primer and SEM 39143 Trim Black Paint.

Most of the time was spent in preparation as is usually the case when painting. Masked the area, cleaned the surface and draped the entire car with sheets, so no chance of overspray.

Two light coats of primer and three light coats of paint. The end result turned out as good as I hoped for. Looks so much better !

Mucho bettero!

Just wanted to say thank you for this thread. I love my ERA 289 FIA, but the one thing that's been bugging me is the way the spare tire tray looks so out of place in its natural fiberglass color, which I think is way too visible from the rear. Glad to see others who agree and who have taken the time to post options. Looking forward to tackling this one.

Sweet.

Cobalt289 06-30-2017 05:57 PM

Done and done.
