Holes in hardtop

I am painting the fiberglass top of my 87 YJ. The PO had drilled holes for a roof rack and filled them with clear silicone when the rack was removed. The holes are sealed well and do not leak. My question is how to prepare the holes for paint?
Thanks in advance for your help.


If it ain't broke, don't fix it - Don't worry, something will break soon enough for you to fix.

How big are the holes? IMO your best bet is to use "adhesion promoter" by duplicolor. It sprays on clear, and all you have to do is paint the area within 20 minutes or so after application.

Personally instead of silicone I'd use this. Then prime and paint

The holes are <1/4" in diameter and presently well sealed. I guess my problem is what will stick to silicone but the resin solves that.
Thanks for the replies.

Even if you got paint to stick, I'm not convinced silicone will hold up long term with UV exposure like the resin would. My guess is if you stayed with silicone you'd be repairing holes again within a year or two.

Any fiberglass resin should be good for this application.

I have done so much with so little for so long, I can do anything with nothing forever.

You could dig the silicone out, paint normaly and then install some nice stainless double headed bolts, there is a fancy name for them, with clear silicone to seal them, in case you or anyone else ever wanted a roof rack again.

Like these.....

I would DEFINITELY just install another roof rack... Call the PO and ask what kind he had and ask for pictures.

It solves multiple of your problems, some of which you didnt even know you had. (Like... The problem with lack of cargo space when 4 people want to go skiing and the roads are too snowy for your friend's honda crv.)

Kind of ****ty for him to have taken it off. Did he buy the same exact jeep again, and just had to have it?? The jeep hardtop racks arent exactly universal...

Btw, you can follow my xj roof rack writeuo and just drill the holes in the mounting section in the same spot as the PO regardless of what he used.

If you want to keep the Silicone then use some adhesion promotor and spray with the rest of the roof. It will probably hold a season or two, but fail before you need to repaint. If you want a permanent repair use some west system or other good quality epoxy resin (not bondo or other polyester resin) and fill the holes. There are various fillers you can select from that will bridge the gap. http://www.westsystem.com/ss/filler-selection-guide You may need to put something like a piece of duct tape on the inside to hold the filler/epoxy blend in place till it cures, or better yet a small piece of cloth and resin will do the trick nicely. Don't be afraid of working with the resin. It really is pretty easy and will give you a much more permanent repair than leaving the silicone in place.

Build a custom roof rack from scratch.

Thanks for all the replies. I decided to fill the holes so I tapped them to 1/4 -20 and got some 1/4 -20 plastic screws at Home Depot which I threaded into the holes and sealed in place with JB Weld. I cut the heads off, sanded them flush and covered them with bondo which I feathered in so there is no visible 'bump'. I hope this holds up and any flexing of the roof doesn't crack the paint.
The roof rack suggestions were great but I don't have access to whoever removed it and the hole layout is kinda weird so finding a rack to cover them seems like a long-shot.
If my fix doesn't work I can always the stainless steel screw route.
Thanks again for the help.

What you did is good. Silicone is just plain not a good idea on jeeps or almost anything else. IMHO.
What you did will last. The bondo a nice esthetic touch but the JB probably sealed just fine.

shackles or D rings?
