Title: Do I need to media blast?
Post by: Charger1973 on December 30, 2006, 12:24:10 AM
Im hoping to do as much of this as I can at home in the garage, so im trying to see what my other options are.

Theres spots like this inside the cowl that worry me too.  Its not rusting through really, but I dont want it to in the future either.

I would be careful blasting roof as its thin metal you'll warp it easily. unless you soda blast it

I'd clean all the old headliner glue off with a scraper and some laquer thinner,wire brush the loose rust off and POR-15 the hell out of it.

Done.


Some people will tell you POR-15 is junk, it's too expensive, blah, blah, blah.

All I can say is I've used it on my cars, and my flatbed trailer- it's held up well and stopped the rust.

Last time I bought some it was $40 a quart-a quart goes along way.

 :iagree:

POR15 it. I had the same issue with my 69 SE. I POR15'd it 10 years ago and have no problems.

im one of the bashers of POR-15 but not because its a bad product, but because some people abuse the stuff and think its a miricle cure instead of doing a good job

The glue holds on the headliner sound deadener (jute padding), to the roof. Not the actual headliner.

That is a perfect job for POR-15. It's not exposed to the elements, sunlight, etc. Hit it with a wire brush, clean as directed per POR-15's instructions, & brush away. It will all be hidden by interior pieces.
BTW, I did my entire undercarriage after it was sandblasted with POR-15, I don't think I used a full quart either. It goes a very long way.

Good Luck!

Por 15 is great for trunk floors, compartment floors and other areas which aren't cosmetic. Under hood Id blast it and see how bad it is. If its just pitted then Id use filler and go on from there

That's ok. I should have known what you meant. My wife (the Upholsterer) gave me one of those looks ::) when I asked her about it...I should have stated  I "helped" her with the headliners.  And apparently wasn't paying attention :rotz:

Sorry no help here with the glue removal issue. most of the headliners we worked on were in allready prepped and painted cars. or in new enough cars that removal of the insulation was not needed.

With that said. If 3M makes a glue remover. It'll be the best. IMO. Always had great luck with their products.

So as long as I clean it up real well, what I can get at anyways...  And then POR-15 in all the cracks.  I should be ok?  I was hoping I could do that but I wasnt sure and I dont want to have to come back and fix it later...

Also, what would you recommend for the bottom side?  it was undercoated and overall is in pretty good shape.  Should I remove all the old undercoating?  Its old and flaky I hate to leave it there.  If I scrape it off then can I just sand and POR-15 that too?  Will I be able to undercoat over the top of that?

Just to clarify my previous post - I brush the POR-15 on. ;)

And you DO NOT want to get it on your skin and let it dry-you can wash it off with lacquer thinner while it's wet, but if you let it set up on your skin-it will be with you for WEEKS!

Rubber gloves and eye protection are HIGHLY recommended  :yesnod:

'Course I usually wind up with a set of black fingers for about a month after I use the stuff ::)

"...Also, what would you recommend for the bottom side?..."

This depends on how full of a resto you want to do. I had undercoating on my 69 and did NOT remove it however I regret that decision now. It's far easier with the trans and exhaust out. I'd do it now if I had it to do over again...

Just my 2 cents.
