Re: [FWDLK] Prep for painting



Kenneth,
 
Additional thoughts/opinion...
 
1. Re: front & rear inner fender color, I sprayed the rubberized black undercoating to the underside of fenders and sprayed a flat black paint to the interior splash pans of the wheel wells.  Reason: as Jim pointed out, appearance-wise they will “disappear” and not draw attention from the exterior paint finish.  Secondly, the rubberized black undercoating protects from flying road debris, although I have not found that to be a noticeable problem on the road.  I am not sure what you mean by “rolling on a bedliner” but it sound too thick, unoriginal-looking, and unnecessary (insert my “opinion” here).
 
2. Re: underhood insulation methods...with the tall convex/concave 56 style hoods there is a great deal of air-movement and very little heat transfer to be concerned about “cooking” the topside hood paint.  Even the compact & hot underhood temperatures in Southern California HOT summer driving (90-105F w/no humidity) there has not been one iota of heat transfer damage/discoloration of any sort to my sixties Dart w/headers and HP 340 engine.  And therefore, even less chance of any heat damage to my bulbous hood 56 Plymouth.
 
Reflection: at one point I was also concerned about engine heat transfer/damage to exterior hood paint on my Dart and installed a fibre hood mat; result was heat retention under the hood (not good w/our Ethanol based fuels or efficient combustion) which impaired mileage & power due to increased operating temperatures of heated air induction into the air cleaner/motor.  Yes, the exterior hood paint was “cooler” to the touch but even with a clear coat finish the potential damage w/o a hood mat was a non-issue/not a possibility.  Lastly, the fibre mat did chafe the paint because it is abrasive.
 
Therefore, I think it unnecessary and unadvisable to install a non-original appearing hood insulation to your 56 Dodge and you will thoroughly be impressed with an exterior paint quality finish to the underside of the hood every time you pop the hood for service/inspection or for admirers at a car show.
 
3. My trunk material was also rotted and I removed all the “visible” matting which left the hidden amount to prevent any rattles (although I am not sure this will be a problem – and if it is then I will add a thin black neoprene sleeve into the remaining crevice) and painted the inside of trunk lid the same color as the exterior paint.  I must say that the non-original color-keyed paint to the underside of the hood and trunk lid is far more pleasing to my eyes than the OEM gray. 
I would definitely steer you away from any silicone or injected material for many reasons... chiefly because of “appearance” issues as Jim mentioned but because all once slightly viscous materials can lose shape/ooze/and become messy & problematic to apply and don’t pertain to addressing body part concerns; unless you are dealing with unseen cavity wax between trunk welds/floor for rust/moisture inhibition.
 
Take care and feel free to email me privately if you would like to see some pictures of my 56 panels/body parts.

My thoughts...

1 - Seems like a good idea.  What I'm wondering about is the idea of painting that area inside the wheel wells body color.  Seems like they should be painted black so they sort of disappear from view when people look at the car.  Even if it's not how the factory did it I would probably paint it black unless I was looking for complete originality.

2 - I don't think the bedliner would be very good at insulating.  Probably better than nothing but if you really want protection I think you need to use a fiberglass mat, with or without the silver layer.

3 - I would not use any silicone.  Every silicone I have used winds up shiney.  I used some black silicone to do just what you are describing but for my hood and the first thing that catches your eye when you look under the hood is "what's that shiny stuff".  Plus silicone doesn't take well to painting and maybe someday you'll want to paint it.  The best stuff I found for sealing stuff and gluing things is urethane (home depot's website shows a wide variety of types and colors).  And it can be painted if you want.  Since you want to still let it move so it doesn't cause the panel to warp I would use the smallest bead I could get away with rather than using a bunch and doing "too good" a job of gluing things together.

This is a bit of a narrative, sorry, but I have a few concerns with prepping my 56 Dodge Custom Royal for paint.  The body is off frame now, so there is considerable latitude to address the issues.  I am not doing a strict concurs restoration, but, standing off, I do not want the enhancements to be apparent.
 
  1. Inner/outer fenders – in ’56 the inner and outer fenders are not lined. Modern cars have a poly liner to protect from road debris. I am thinking of rolling on a bedliner on the inside of the fenders on top of epoxy primer.  This will allow for the undercoating type of protection and provide a paintable surface so body color paint can be applied like was done at the factory.  Is this a good idea? Any tips on getting the bedliner to go on approximately smooth.
  2. Hood – In ’56, for the most part, hoods were unlined allowing engine heat to cook the paint.  In the 60’s, a fiber mat was added for insulation from engine heat.  In the 70’s aluminum foil was added to reflect the heat in addition to the fiber mat.  I would like to add heat protection for the hood paint.  Would the bedliner painted body color idea from the fenders work?  Any ideas on making it look good?
  3. Trunk lid – the asphalt mat between the lid frame and skin on my car was deteriorated  beyond repair, so I slid it out of the trunk lid in chunks.  The trunk interior was painted Dodge dull gray, including the rotted mat.  The mat allowed the skin and frame to expand and contract without binding and provided anti-rattle protection.  I am planning on painting the trunk lid body color (much better than dull gray J) and after painting, I plan on masking the frame ribs and skin and injecting Black Max gasket silicone between the skin and frame and tooling it smooth.  When the masking is removed, a smooth thin black line will be visible between the skin and frame.  Will this cause binding/warping and will this provide anti-rattle protection?
 
Sorry for all the questions, but thanks for the help.
