PLEASE help!!!!

Skywalker

A buddy of mine decided the other day to take all the stickers and stuff off his guitar and give it a good clean.

Unfortunately after taking the stickers off and wiping it down with some household cleaner(I'm not sure what exactly) he ended up with this ? ???

Is there an easy, inexpensive way of possibly "fixing" this without having to sand down and re-spray?

Any help would be HUGELY appreciated 8)

Sorry , i think a repsray is needed. One could use stickers to cover it i spose or just leave it as it is ..

I think there's no other option than for him to sell it to me... and with that paint damage I am sure he will be happy to take R500 for it ?

Hmm.. I know Methylated spirits gets that sticky stuff from stickers off... HOWEVER, i also know it can do some nasty stuff to paint, so I duno if you wana try that.. :/

Skywalker

Thanks for the input so far guys.

Giggsy - I know he want's to sell it. Just don't know if he'll take R500 for it though :-\

Looks like a Mr. Min job to me ... that stuff kills clearcoats.

He can try using some burnishing compound and cutting some of the clearcoat back by buffing with that.

For future ref: On Poly coats, cleaning benzine should do the job to take stickers off. Don't try that on Nitro though.

Relic the guitar...

What I'm seeing is dullness from an abrasive, so it is likely a Handy Andy type "cleaner". It's a Polyurethane finish, which is inert, so it's certainly not chemical damage.

+1. Polishing compounds will work. Burnishing compound is a little different - it's made for machine polishing where you heat up and melt the finish with the polishing process, which results in a very high gloss - not a technique to be tried by a newb and definitely not on polyurethane.

Naphtha is best for removing stickers and is safe on all finishes. Commercial "lemon" oil works well in a pinch as it's mostly naphtha anyway.

I'm not putting Mr. Min on MY poly finishes!! Pledge fine, Mr. Min ... no way!

Alan your response is a bit confusing. You're saying +1 and then don't use it on Poly which is what I said he can do. My point being that burnishing compound is widely used in automotive circles on exactly that ... Polyurethane.

Next time you're in town, remind me to show you the clouding in my Yamaha's (Poly) finish ... caused by lemon oil.

Sorry that it sounds like I'm trying to disagree on all fronts, but I've used Burnishing Compound on a poly finish before (applied by hand ... sponge initially); and I have the cloudy marks on my Yamaha to show for Lemon Oil. And, yes, I'd agree if you say not all lemon oil products are the same ... Naphtha mixed with a bunch of other stuff ... the other stuff being the potential problem for a finish.

My feelings on Mr Min are well known. ? While it shouldn't harm a true polyurethane finish (which is chemically inert), it can make future repairs or finishing difficult - especially when it penetrates through screw holes to wood. Anyway, I was just saying the damage in the picture was caused by an abrasive cleaner rather than a chemical interaction.

Sorry - that wasn't clear was it? The +1 is to needing to cut back the finish and polish it up again. Burnishing compound works (in fact it's nice in the way it breaks down and becomes progressively finer the longer you buff), but when working by hand, polishing compounds are far easier and more consistent. The burnishing compounds used in the auto industry are applied by machine.

Interesting. Not calling you a liar, but it shouldn't cause clouding in a proper polyurethane or a polyester. But then the chemistry of paints is a huge subject and I don't know everything. Lemon oil duly added to my sh*t list.

No Problem. ? How would I learn new things otherwise?

Skywalker

Finish sorted ?

Polishing compound and a bit of elbow grease fixed it up perfectly.

Thanks a stack for the help guys

Much appreciated 8)

Skywalker
