so i finished the paint on the gsxr, i went to lay down a spot of gloss black over a scratch on the tank and the side though n the paint goes on glossy but when it starts drying thats when the cracking starts
WTF?

can is well shook, surfaced is scuffed, any tips?

 

did you sand primer or clean the area first?

 

lay down very light coats let them dry before u lay down another coat ,and temperature can be a factor

 

its been primered and painted, the scratch just happened today it went down to the primer so its not bad, i cleaned it and ruffed it up with the brush side of a sponge n then shot a light coat of the black

 

dam this got moved fast

 

what type of paint are you using to touch-up with?

 

it cracks? or does it fish-eye? kinda like wrinkles up? Try cleaning the area with mineral spirits or laquer thinner before painting it again to remove all oils and what not

 

make sure it's sanded in that spot good enough then wash it like cisco said to get any oils off it, then dry it with a clean paper towel and try the paint again

 

wrinkles up, using rustoleum

 

theres ur problem rustoleum does that ,use enamel

 

stupid rust stuff!!!

 

if it's wrinkling then there is oil on the surface, use laquer thinner, it is your friend!

 

simple green

 

you're pretty much fuked. time to strip the tank and repaint. Whoever did the last paint job on the tank didn't get the mix ratios right and the paint didn't cure properly or your tank has too many layers of paint on it-the solvents in your new paint are stripping off the old paint. Don't waste your time trying to "fix it". You'll be way further ahead just starting over take it from someone who's been there.

 

what ever the case, there is more work for you than you intended.
