I am not really sure to be honest. I was just a delivery driver for my local Napa for many years going through college. I just knew of the products that came through on a regular basis. I don't know if SEM makes a color in like you described but If you have a local Napa or auto parts store that mixes paint, they might be able to color match a single stage top coat that might not require a clear coat. If they have a person who mixes paints regularly and really knows his stuff, I'm sure they could point you in the right direction.

I used a single stage top coat on the inside of my hardtop (a few posts up). It turned out kinda glossy but I don't really mind it beings it's inside of the Jeep. For an outside semi-gloss matte finish you will probably need a flattener. That may require a clear coat with the flatter mixed in because the flattener could not be mixed into the color if I remember correctly.

Hopefully this helps!

wm69 Question, since you worked with SEM products at NAPA.

I have Honey interiors on all of my CJ's, and the SEM vinyl spray coating in Camel is a perfect color match for Honey. Can you get an SEM product in that color that would hold up well as a topcoat on a hard top?

Deer-Slayer_5 Thanks for the info Keith. Mine is polycarbonate then. I don't have the lines you showed in your pictures. It make sense to me now that the PO probably got the doors with his hard top and they are a pre 80s style door. My Jeep is an 85 but I honestly prefer the twist handle doors vs the paddle flap door

It's according to what year your top was manufactured as to whether it is injection molded polycarbonate or SMC fiberglass.

The polycarbonate hardtops were produced from 1976-1979 or 80. Somewhere around late 79 a lot of changes were being made to the CJ series and some of those changes included the hardtops. 1980-1986 and beyond, the tops were produced using compression molded fiberglass or SMC (Sheet Molding Compound) fiberglass mixture.

The easiest way to tell what type of top you have, polycarbonate or fiberglass, is if it has the four piece seams on the outside, between the side window and door frame opening as well as the rear section all the way around. Tops without the seams are polycarbonate, with the seams, is fiberglass.

Example: picture below is a factory SMC fiberglass top I acquired off of a 1985 Jeep CJ-7 Laredo.

Deer-Slayer_5 Finished up painting the hardtop last night. I didn't want to paint the inside but because I got some over spray in it, I decided to go for it. Ran up to Napa and had them mix up some 9B, Olimpic white paint that AMC put on their Jeeps. I dont know if this was the exact color but it was white and original to Jeep. It all turned out great with no issues! I haven't pulled the tape and plastic off yet. This weekend I am going to get the windows in. I hear this is pretty tough but its gonna happen. I think I need to cut and glue the rear window seal, its a little to big.

I am not 100% sure its plastic... I found on a forum here awhile back that earlier tops were a one piece polycarbonate then switched to fiberglass at some point. I hope someone can clarify this because I could have a aftermarket top and not know it.

When I dug into the top with the dremel tool, it was more of a resin based polymer with no fiber material mixed in. That being said, if it is a polycarbonate top, the paint could potentially be absorbed by the polycarbonate to an extent. That kind of material is porous and can absorb petroleum based solvents and paint, especially if they used a polycarbonate with a glass filled option for strength. Hopefully my engineering talk didn't confuse the heck out of everyone...

To answer your question, I did 2 wet coats of the top coat. I did have to go back on some spots and touch them up because it looked like it absorbed a little and you could see some white. Then I dusted the roof with the remainder of the paint I had. You could see my paths on the roof so I decided to change direction and dust the roof.

I updated my procedure in my last post. I forgot to mention some stuff about the texture.

Jim1611 What size ball fits the hitch on that trailer? I want to make sure I have the right one with me when I come and pick the top up!! Nice

Hoover7 Man that texture looks great, really impressed with the final finish Really appreciate you posting your procedure as well, as I'll be trying to emulate your results.

Hard top TEXTURE repair

Alright everyone, this afternoon I was able to get the textured paint on the hard top and paint it black! I must say, at first I didn't think the texture was going to make it look original. I was wrong! I am very pleased with the result!! If I had not painted it myself, I could be fooled into thinking it was a top that never saw daylight. So here is what I did!

1) I cleaned the top off of any dust with a dry towel and then ran a tack rag over it. Mixed my textured paint up for spraying. The specific paint I used in my previous post did not have to be reduced but it can be if needed. I didn't use any reducer.

2) Test spray! It took me about 10 minutes to get the spray I wanted. I was just using the purple gun from Harbor Freight. I think we ended up using a pressure under 5 psi. Yeah, lower pressure gave me bigger drops like what was currently on my hard top. If someone does this method, play around with it before you spray it. Also, always have a rag handy to clean the spray tip. The paint seemed to build up a little after a few minutes.

3) Spraying the top. It does not have to be fully coated black, you will want to put a top coat over the textured paint. I found it best to be about 6-8 inches away with my given pressure. Again, this is something I had to play with. When spraying, I found it helpful to spray kinda random, shaking the gun and sometimes found myself going in circles but this is something that you can do if you wish. With this texture paint, I got a cotton candy like strands that came out the spray gun. This is normal. This is the gun air pressure game. Too much air pressure will make it stringy.

4) It says the flash time is 5-10 minutes. I let it sit about 30 just so it was dry. I have some "Hot Rod" black paint made by SEM. It was a kit I bought at Napa. It has all you need and 1 quart did the whole top. I mixed that up and it was applied like regular automotive paint. (following their directions other than not using their primer) Before you spray the top coat, be sure to take a dry towel and wipe off the top, following with a tack rag. Those strands I mentioned in step 3 are basically dust. It is also good habit to tack rag before you paint, especially outdoors like what I did.

Some discoveries I found while spraying:
The top coat that I sprayed seemed to soak into the top. My top is believed to be from the early to mid 70's. It's plastic and not fiberglass. Mine also has no seams like the 80's tops have. Does anyone know the history of the hard top materials?

Renegade82 Ahhh, this takes me back. The rust, the rust, the rust! Your doing a great job. Don't get in a hurry.
Now somebody pass that popcorn. And yes, my 82 came with a factory blue engine. I believe they called it seafoam blue from the supplier.

Will do! That was my original plan. I know there are a lot of different ways to fix these tops, texture them and what not. This is a totally new approach on here.

Just be patient with the updates... It has been stupid hot, humid and rainy. It's hard to spray in this weather for obvious reasons so If I do, its early morning when it's cool. I am going to try for this weekend if I have the time.

Hoss,

Nope. The top will be textured! I have searched pretty hard for a textured paint. Sherman Williams has a paint that you can mix but it is expensive... The hardener they require is over $200 a gallon... the paint itself is about $100. NOT doing that lol

Instead, I am going to use SEM 39854 Texture coating. I used to work at a NAPA auto parts that mixed paint and we sold this stuff. Did some research and bought a quart. The spots I repaired have been sanded down unfortunately but I wanted it textured.

My plan is to leave the rest of the texturing and to just paint over it. It wont be noticed in my opinion but I am going to test it first.

I'm with you though, I cannot stand the smooth tops.. even on the new Jeeps they just don't look right.
