powder coat removal question

[sswee]

I have had 5 gal soak cans of carb cleaner marked Oxalic acid mixture and the one I am using currently is marked Cresylic acid mixture. I agree that work very well stripping PC. The only downside I have is the price. Like FSTFBDY said it runs about $80 a 5 gal bucket.

Did it strip the powder from your parts cleaner?

Went by NAPA last week... the price went to over $125 for a 5 gal bucket...

The problem with using spray cans contains paint stripper (we sell 3 types VHT Permatex and Krylon) is that the solvent evaporates away from the part very quickly. With the solvent gone, you are wasting your time.

SOLUTION!! Spray the part, then immediately place some GLADWRAP film over the spray. This holds the solvent in, and makes it work on the paint.

These cans are fairly economical used this way, and they certainly get into the awkward spots.

You need to ensure the material you use has the generic name of METHYLENE CHLORIDE. aka 'aircraft stripper'.

If you want to soak something, get NAPA lacquer thinner about $10 per gal, or MEK (Methyl Ethyl Ketone) or a mixture of both. MEK evaporates slower then lacquer thinner.

Also Caswell SP Degreaser, run at about 180 deg f will do a mean job of paint stripping too.

How long does MEK take ??

Question 2.... will it tarnish polished aluminum ?? I really hate polishing the entire rim after I strip them..


Just for reference, I use a dip tank..

Just for info...

I ordered some stripper from Solvent Kleene a few months ago to strip factory coated wheels..

Needless to say, I am disappointed with it.. The shelf life is not good at all for almost $200 for 5 gallons.. I bought 10 gallons of the stuff.

I have had a wheel in there for over 24 hrs now and it hasn't even started to strip it yet.. It worked good at first... but its not worth the money.

Plus the salesman that I spoke with didn't have a clue why its not working anymore... What a joke..

Need to find something else...
