Stripping...

Is there certain types of finishes that you can't remove? Such as the solid, plastic-y finish, polyester I think it is?
 
Re: Stripping...

Polyester. It laughs in the face of paint stripper.... And acetone.... And acid..... And whatever else you throw at it.....
I removed it using a combo disk and belt sander with 80 grit paper. Also don't forget there may be a thick epoxy undercoat that's harder than a pedo at a preschool to remove.....

Yup!
 
Re: Stripping...

yeah polyester is a b!tch and a half to get off. But a heat gun and scraper will help significantly.
 
Re: Stripping...

There really isn't anything that is commonly used on guitars that you can't get off cleanly, with enough elbow grease and chemicals and/or heat.

You know, I was told the same thing but when I came face to face with the dreaded squier paintjob, the heatgun did as much as if I'd just used a Chinese paper fan. In fact, that squier polyester is so tough, I'd suggest they coat their troops in it before they ship 'em off to the Middle East....

That being said, a heatgun will work on most other poly style finishes.

Sorry,

heat and chemicals won't touch the poly...ONLY lots of elbow grease and grit (or a good belt or disc sander).

If you use enough heat to strip poly, you won't have any wood left in that guitar.

That's pure hogwash. Heat and chemicals work quite well on poly. Just get the right chemicals. Do you think I just pulled that out of my ass?

Doc is wise hear. Why bother?

Well, I have no idea if you pulled it out of one of your body orifices.

So tell me...what chemicals have you found that remove the poly "cleanly" without needing a beltsander?

I never said anything about some magical chemical that will just make poly slough off without any other work required. I said:

That means that it takes a combination of techniques, and it always takes elbow grease (i.e. sanding).

Rough up the surface with sandpaper (by hand, no belt sander required). Then use a stripper that is designed to remove epoxy and other plastic finishes from airplanes, not some hardware store stuff that barely even strips house paint. When you say chemicals won't touch poly, you act like no such thing exists. It's ridiculous. I've stripped polyurethane and polyester off of several guitars using primarily chemicals to do the work. No, it ain't fun, but it can be done. And it's a hell of a lot cleaner than using abrasion alone.

I understand combination techniques, but the chemical still has to dissolve/loosen the finish or you might as well not even use any.

So, you still haven't said what chemicals you use to strip poly.

And where can you possibly obtain such chemicals (that are available to the average guy)..

I did a quick Google on stripping poly off mahogany and got a boat refinishing forum that suggested strip-EZE in the pink container or Jasco paint and epoxy remover. Or a heat gun, or a belt sander with high grit count.
Its good knowledge to me as I'll probably be stripping my scarab sometime this year.

Re: Stripping...

I just throw $1 bills at the guitar I want to strip. My friend is an ***hole though because he throws quarters.
 
Re: Stripping...

Heat gun worked great for me on a couple poly guitars and I used Citrustrip on one a while ago if memory serves.

I have said that I use aircraft stripper, and I get it at an auto paint supply shop. Would you like the address?
 
Re: Stripping...

I tried an industrial quality heat gun on a polyurethane finished guitar and it did nothing...I mean NOTHING but make the guitar feel hot. The poly didn't even soften enough to scrape off...just left a few small scratch marks. I tried every paint stripper that Lowes and Home Depot carry and left it on for hours...didn't touch it at all.

But I'll check out the pink Strip-Eze and the Jasco Jon mentioned.

Are you sure it wasn't polyESTER? That's the hard one.

People always go on about poly like its one thing... There's many different plastic finishes that they just lump together as poly. The common stuff on the cheap guitars is polyester because they can lay it on thick and it's pretty much bulletproof.... And when it chips it comes of in chunks.
