18 Jl windshield (frame) repainting advice

[h77_mar]

My 18 JL has the typical corrosion (galvanic? I think it's called) for the most part its just bubling but one spot has flaked off. Im looking to get something done about it, but I'm concerned if I take it to a shop to just get the windshield repainted that it will happen again. Is there any special process involved with this typoe of repainting? Or am I good to go with a regular paint shop type of job? I have put some thought into having some part of the jeep painted with bed liner for Wear resistance. Would that be something that may hide/hold up longer term than normal paint?

You're getting your windshield repainted??? Maybe you meant hood?

Windshield frame? To do that properly, the windshield glass needs to be removed. It can’t be reused, so you will get a new windshield out of the deal.

The easiest, and likely cheapest way would be to get a new windshield frame, have it painted, with new glass, then just swap it for the old one.

Why not just repaint the one on it? Either way Id be replacing the glass, so why get a second one?

No need to completely strip the paint down to bare metal, and repair the corroded portion. Saves money on labor, which is the most expensive part of the repair. Ask the shop when you get an estimate.

The windshield ca, if removed carefully, be re-used (I’ve done exactly that).
The frame is likely repairable/repaintable, a good paint shop will be able to advise on what is needed to reduce the chances of it corroding again.

I am British, we still don’t paint windscreens .

I didn't realize it was called a windscreen there. Here "screens" are porous to let stuff smaller stuff through. Like a window screen, which lets air through, but not bugs.

would it be best to repaint it with paint or something thicker/more durable like a bedliner? Ive already thought over doing that for branches hitting the frame but Im thinking maybe a thicker coating like bedliner might not bubble or at least not be as noticable if it does?

I am not a professional painter but have painted my Chevy Nova 3 times in the last 24 years. I have also painted parts on my Harley.

When I got the Nova, it had the same rust you described. I repaired the cancer by sanding down to metal and using fiberglass reinforced body filler. It has never bubbled up.

You have options all dependant on skill, time available and money. Here are two.

1) Easiest but most expensive: Take it to a reputable shop and have them do the repair or replace/paint the frame.
2) Cheapest, most time and skill involved: Do it yourself. Have glass removed or remove glass, sand down to metal, treat metal with rust inhibitor, use body filler, primer, sealer, paint and clear coat. Will take skill and time. Dry times, sanding, paint curing depending on hardener used, etc.

The quarter panel on pic 1 had rust, picture 2 is after paint, before wet sanding and polishing.

I hope this helps

Best

Bedliner looks good for a couple years, then starts to get a coal-like look and looks pretty bad, IMO. I'm not a fan of the stuff.

If this is an aluminum part, the process used on airplanes is to mechanically remove the corrosion, acid etch, then Alodine, then zinc chromate prime the surface, then paint. Jeep basically skipped the etch, alodine and sacrificial primer steps. They didn't seem to know squat about protecting aluminum.

I am British, we still don’t paint windscreens .

Windscreens, boots, parcel shelf, bonnet, chubby box…you can understand the confusion.

I'm getting up the energy to attack the corrosion on my doors and hood. These are the products I plan to use. I've used them successfully on airplane aluminum structures in the past.
Bonderite C-IC 33 Aero (Formerly Alumiprep 33) | Aircraft Spruce ®
Bonderite M-CR 1201 Aero (Formerly Alodine 1201) | Aircraft Spruce ®
Epibond Epoxy Primer - B-6433 Base Dark Green | Aircraft Spruce ®

We do still say hood but it’s the roof of a convertible - how you guys moved it to the bonnet is beyond me.
Unsure what a chubby box is but it’s you guys that messed around with our language
