Touch-up paint question
 
Dr. D-- Ok, who else would I be asking? :D -- I have a touch-up question for you.

I just applied framesaver to the inside of one of my frames, and during the process, it poured out through various holes and ran down the outside of my frame. Perfectly normal. I wiped it off, but there's still a sticky residue on my frame. The problem now is my next task is to touch-up some chips, and I'm thinking with the framesaver on the paint, touch-up paint won't adhere properly. So how do I go about safely cleaning my frame so that paint will adhere?

wipe the whole thing with solvent? you should do that anyway.

???!

Ya think?

"Solvent" is a pretty broooad term.

Mineral spirits is one thing, laquer thinner or acetone is going to take paint with it!

For Blue Order; My first line of attack would be PPG's DX330 Wax & Grease remover.
To clean out a chip in the paint, I would scrub with an old toothbrush dipped in DX330, then using an air hose, blow the chipped area dry. Then surface clean according to the instructions on the can.

Which you could do to the whole frame before polishing & waxing, to remove dirt, and grease that may contain dirt. That way you aren't as likely to scratch the frame as you polish.

NOW you should be ready to proceed to touch-up.

So where does one get this PPG's DX330 wax and grease remover?

Under "Automotive Paint Suppliers" listed in the Yellow Pages.
Look for a nearby PPG dealer.

And while you are there,...

~pick up a box of 100 single edged razor blades. Probably THE cheapest place to get those! It's $3.25 at my paint store. "nickel knives" I call 'em! :p

~Also another handy around the house item is the 3M General Purpose Adhesive Cleaner! GREAT for those NASTY price tags that refuse to come off!

Being presumptuous I suppose. Mineral spirits is the sort of general purpose solvent I keep around, and I expect other bicycle enthusiasts would keep around. Lacquer Thinner is a bit overkill for most purposes, but I suppose I should have been much more specific.

I actually considered mineral spirits, and know that it wouldn't harm my paint, but wasn't sure how my decals would fare.


And thanks Dr. Deltron-- I'll get the supplies you suggested!
