To strip the old paint completely or not

Years ago, I worked at a body shop and Old Ralph used to say if the old paint is solid and stuck leave it alone and work on the loose stuff. His paint work was first cl***. I learned a lot from him. Iceman

 

Strip it bare and reprime. Not only will it get rid of latent rust, I had some issues where the new paint shrunk up in spots where we didn't take it to bare steel. It's better to remove a variable. Bare metal isn't just for vanity, it's a clean slate.

 

Always remove old paint. Our shop won't paint over anything but freshly blasted and properly primed metal. All that work...why gamble?

You never know whats under there anyway...

 

If you are painting a 50 to 70 year old vehicle it would be wise to strip it.

That be true NTX .Shops doing work for customers have a duty to do it this way.That said there are some that this is a hobby for and limited budget . Having a car completley blasted is huge deneros and outside of most peoples $$ reach . If that is the reason then maybe they have no option but to paint over what lurks underneath and enjoy their car none the less . Not ****ting on you at all . Just stating money always stands in the way of what people desire and what is realistically within their reach .

 

I alllllways would want to strip it to bare metal...i want to know whats underneth...course as a kid i peeked under my christmas present wrappers..and im alot OCD...

 

So aw1950 your budget covers the potential of a repaint? There once was a time that my shop did not have the facilities for blasting, and I stripped many cars by hand. Cost next to nothing but took a lot of time. Still was a policy to remove paint even then.

There were a few issues that i experienced at my shop and other shops i worked at before becoming an owner that led to this policy.

Yes my car will be repainted . I am one of those guys that tackles all aspects of my cars transformation. From metalwork to paint to interior . Don't get me wrong on this I was just stating that a lot of people don't have the funds for blasting . My car is in the process (over time) of being put to bare metal and I will epoxy prime it before doing any kind of bodywork . This is information for others to use when it comes time for them to decide on which way they want to go . Experience is the best teacher and obviously you learned that stripping is definitely the way to go . I was just putting it out there !!

 

Stripping and blasting has been the demise of many a car.
There are plenty of nice driving vehicles that need a paint job. They get completely blown apart blasted and never see the road again.
The reasons are different but the end result is the same.

Most car guys, and even quite a few normal joes can handle the work of a scuff and squirt new finish. Not most can handle the full blown blast or complete dismantle, this is a lot of midnight oil dedication or a pro job to completion.

There's no doubt that a properly done bare metal up job is best, but you had better make the commitment or you'll have a lump and pile of parts instead of a neat car.

This is really a very old problem.

28 For which of you, intending to build a tower, does not sit down first and count the cost, whether he has enough to finish it— 29 lest, after he has laid the foundation, and is not able to finish, all who see it begin to mock him, 30 saying, ‘This man began to build and was not able to finish’?

Do what you think is best for you.

 

I was in a discussion with a couple of body guys yesterday that said basically the same applies to laquer primer as well.
Surprise to me as I've got a gallon of that ready to be mixed.
Anyone have thoughts on this?

 

My thoughts - 0.02 worth.
Lacquer primer is great for a guide coat.
You can sand it right away but it shrinks
Been used for eons before Catalyzed stuff

The thing about lacquer primer is it needs to sit for days and get all the shrinking out of it before the blocking. While its sitting its also acting like a sponge. Some times and places this isn't a problem, sometimes it is.

So basically there's no consistency or stability.

My buddy specializes in minor touch ups, blends and used car quick fixes. Fast turnaround is the key to his clients and business. Has is own fully stocked paint mixing room and really knocks this stuff out at really fair prices. He uses lacquer primer because its fast, his work is near flawless most of the time. The longevity isn't there because the lacquer primer shrinks.

 

Bare metal and quality products.

 

I agree taking it down to bare metal
that way no problems
it is easier to do it right the first time

 

Lacquer primer re-liquifies with todays solvents. Putting urethane anything over it is a no no. It also loves to shrink for a long time causing adhesion issues.

 

I am not a body guy but mine had lacquer on it the more I looked at it I thought it was best to strip it because I didn't know what was under it didn't want it to come back to bite me

 

Thanks for the responces as we all can learn something from each other . Isnt this what this is all about ? Sharing knowledge ?
