Oil Can Effect

[ninjanick]

So the floor pans are making some noise when weight is applied then removed (aka getting in and out). I heated and cooled each floor pan. The passenger side took a few cycles and now it's great, but the drivers side is still making noise. I've been trying to heat and cool the entire floor pan, but now it's bowed up and still makes noise. To remove this annoyance, do you have to heat/cool the top and bottom of the panel in question?

What heat source did you heat with? Did you do one large area or multiple? Did you heat til glowing red? How did you cool?

[ninjanick]

I used a propane torch and heated multiple areas at a time. It didn't get glowing red ... hot enough to make the cool rag uncomfortably hot. I am using a shop rag in some cold water.

I had no luck with propane. Try mapp gas and heat one small 2 inch area at a time until its red hot. I started in the middle and worked my way out. About 3 in on center. Ended up with 12 heat points per side

Did you try to localize the spots where you had the most deflection?

[Kurk818]

I couldnt find any particular point that was popping more than the rest. Heating and quenching tightens up the metal. When working around from the center, if one area seamed to tighten up sufficiently, i would focus on the ones that didnt. I ended up using my oxy/acc torch because i didnt like waiting for the mapp gas to heat up

I would be more inclined to use a non-perforating dimpler before heat.

But who has a non-perforating dimpler just laying around? And wouldnt that require removal of the floor pan to accomplish?

Both methods would require paint touch up.

How are people touching up the powder coat after using the heat method? Just hitting it with some clear coat, or something more elaborate? My passenger side is good, no popping, but the driver side is pretty obnoxious (I actually avoid sitting in the car and putting my feat down when my daughter is sleeping in the room directly above the garage - works for now with no body/doors, but it's going to get tricky real soon).

I give it two coats of Por15 after a light sanding and wiping down. It's barely noticeable.
