Painting inside the doors., What did you do? Options

[Olympic 914]

Considering getting my doors media blasted, probably soda blast. and was wondering how did any of you guys paint the inside of the doors?

can't really get a spray gun in there. I used some of the Eastwood inner frame coating inside the longs and the tunnel, but the inside of the doors will get water from rain and wash water running down into them. I think they will need something more substantial inside.

I guess I could just get in there with a paint brush and go to town

I have used Rust Bullet on the inner fenders and underside after sanding and sandblasting. this would probably work inside the doors also.

What have you used?

I have doors without the safety bars and there is a tar like coating inside, hopefully the media blast will remove it. it will be a PITA to scrape it out I think.

Also would you recommend putting something like dyna mat in there or spraying a coating like Rhino liner inside to cut down on noise and add protection ? Not a racer so weight isn't important.

I haven't taken them apart yet.

Eastwood rust encapsilator.

Once bare metal is exposed, use POR 21 or equivalent to prevent rust from forming, especially at the bottom of the door. Many of these products now come in a rattle can format. You can follow up with paint top coats, undercoating and/or sheets of DynaMat or equivalent for noise attenuation.

Wouldn't the Dynamat (or similar) just trap water inside the door? I'm trying to figure out the best thing to do here also. I would guess that once the doors have been properly blasted and cleaned up that rust encapsulator and then a layer of paint is best.

Hmmmmm.....so maybe I will not go with any Dynamat stuff at all.

Now of course, one thing you need to do with your car is make sure there are no leaks. With a 914, that might be a little bit impossible.

Talk to a painter before you start using por products.

Yuck

I was planning on using dynamat on my firewall too. I have used it before and the stuff I used was like tar with an aluminum facing, didn't think it would hold water.

(IMG:style_emoticons/default/agree.gif) it's junk.

Turn your gun down just about to a round pattern, turn the pressure back a little and just hose the inside down. You will have to manouver the gun quite a bit and go fomr one hoile to anohter comstantly twisting, but with a little patience you can get it properly covered with real paint

Anything that can be done inside the door for sound deadening? Soounds like "yes" but you run the risk of a dynamat style product retaining water in there.

Yea, you can get in there.

Cleaning the inside was a major PITA !!! There were some big chunks of body putty that had no purpose.
Getting way down in corners was a challenge (IMG:style_emoticons/default/ar15.gif)

After sealing everything inside with Eastwood rust converter, I brushed
a healthy coat of truck bed liner in.

Edit: Oh yea, make sure you keep the drain holes open !

I have used DEI Boom Mat spray on allot of stuff.

It works but does not have the weight of a sheet of Dynamat or Boom.
So it takes a few layers+ to get anywhere close to the mats especially at low freqs.
