RattleCanning my Rims and it peeled RIGHT OFF!!!
So I RattleCanned my '03 KLR650 Rims a beautiful Satin Black only to have the paint peel off easier 'n a hooker's shirt on Saturday night. NO, REALLY! If I cut/break the paint surface I can grab aholta the paint and it pulls right the ____ off like a piece of masking tape... MAJOR BUMMER! I worked real hard on those frikkin' things!
SO! What did I learn today BoysNGirls??? 'Sounds like a Surface Prep issue more 'n a Paint issue to me, at least after some additional research (once I came out of my depression).
Biggest mistake was several-fold methinks:
1. Surface not sanded past ALL oxidation (I believe Rims shoulda been brightNshiny metal after the sanding).
2. Surface was sanded several days prior to 1st Primer application. Just before Self-Etch Primer 1st coat I swiped with acetone and blew with compressed air, however, leaving aluminum exposed for more n a day or two allows oxidation to come back quickly.
3. Primer not sanded.
4. Surface prepped final with Acetone wipedown that left the slightest haze as it dried quickly in the sun???
A) 4 light coats Self-Etching Primer. B) 4 light coats Rustoleum Gloss Black. C) 5 light coats Rustoleum Satin Finish. D) Temp was 100 and Humidity 30% (within guidelines of Rustoleum).
So, what now?
'Could Anodize? 'Bet I gotta de- and re-spoke the Rims... THAT'S A BIG "NO-CAN-DO!"
Epoxy? Same as above I bet, prep requires Rims devoid of anything but holes.
Or Try, Try, Try again?
I would love suggestions to avoid the same thing in the future painting of the Rims if anyone has some Pro-type advice for apparently a rank-a$$-amateur (especially along the lines of Primer). Many thanks from the Noob!
