Wheel well liner paint

[Calan]

It seems that no matter what I try, I can't get paint of any kind to dry in areas of my wheel wells. I've tried cleaning them with paint thinner, acetone, brake cleaner, alcohol, Simple Green...etc.

I've tried Duplicolor engine paint and bed liner, Rustoleum engine paint and bed liner, plain old Krylon spray paint, and some other brand of liner that I can't remember.

I STILL have areas that refuse to dry; the paint just stays wet. I'm guessing there is something in the factory paint that keeps weeping through the new paint, but how do I get past it without stripping everything to bare metal? (Which would be a royal pita.)

BTW - I still have a a strip of undried paint about 5" long along the seal material just behind the brake reservoir...same type of deal.

Any ideas? This is wearing me out

Seems like I read someplace that paint won't dry on undercoating. I think the oil keeps the paint soft and doesn't let it dry out. Hopefully someone with some painting experience will chime in.

But it's the factory white paint that my stuff won't stick to...and it's dry to the touch after you wipe it down.

Now as for what's under it, I don't know.

are you ruffin up the areas that you are painting.

That helps make a bond with old paint and new

3M makes a rubberized undercoating spray can that i used... i cleaned the wells up with simple green a few times and then sprayed them. they came out pretty good, paint stuck in all areas.

I'll have to dig around in my garage to be sure, but I think the other liner I mentioned was 3M

Why not just get them powder coated?

Go to walmart and get a can of the roll in truck bed liner you put catalyst in. Roll it on let it dry and tell me thanks when it works. The prob is that the chemicals you use are pre catalyzed and if all properties of the prep are not spot on the chemical reaction wont happen. The roll in liner could give a crap if the surface does not shine it will stick. Prep with a real prepping agent like mineral spirits first then scuff any shine off put the hardner in roll it on and walk away. Or if you like the funny feeling stick around and sniff the goodness. It will work i have used that crap on just about everything including a few ak47's. Get some mineral spirits to prep the surface.

Hmmm... so it comes as a 2-part kit like bondo or epoxy?

Would prefer something in a spray can, but I'm willing to try just about anything at this point.

 

[quayzar590awd]

yes sir it does. You will have a bunch left over so if you wanted you could hit your trunk area to reduce road noise or the under side of your bumpers to resist scratches, you can put it on rims or just about anything else.

The wheel wells?

several grand later you have the best looking wheel wells on earth that no one even looks at.

Yeah... hauling my chassis to a big enough oven would be a biatch. And it would probably wreak complete havoc on all the plastic and wiring. And of course I'd have to kiss my interior goodbye.

I'll swing by Wally World after work and see if I can find it...thanks for the tip.

Oh shit wow, don't I look like a wiener
My bad man
My bad....

 

[quayzar590awd]

SOOOOOOO did you pick up some of that special sauce and give it a whirl. I just went and looked at the conditions of mine and it looks great over a year later. I hit it with the hose to knock some of the crud off and it is money in the bank again. No chipping as of yet.

 

[Calan]

Walmart was out of it... the parts stores had some, but it was one part roll-on stuff and HOLY CRAP was it expensive; $87 or so. (even at Walmart the tag said it was around $45). WTF

So...the wells are still on hold.

 

[quayzar590awd]

90 bucks holy crappppppp that a rip. 45 sounds better but its like 31 bucks here. I guess they know every person and their mom drives a big ass jacked up dookie truck around here so they give us a break.

Is this for the plastic wheel well liners? Why paint them? WTF

 

[Calan]

No...the exposed metal areas.

After some cleaning, my plastic is in good shape.

I hope no 1 is so stupid they cant figure out how to clean plastic. spray on cleaner wipe off repeat. Granted I have cleaned about 20 lbs worth of crush and run out of mine but they still came clean after hours of cussing and scrubbing so there is a degree of difficulty to it but plastic does not let much adhere to it thank chemists for that one. I also have used a product called POR 15 calan its in a rattle can and can be had at jc whitney any many other automotive supply companies.
