whenever i've sprayed paint it tend to crack and chip/flake off really easily

am i thinning the paint too much? its cellulose, and i'm thinning it to the ratio on the paint, 1 part thinner to 1 part paint, but it always looks really thin and watery. should i be spraying a bit thicker?

sounds like bad prep......you need to make sure the suface is well keyed, bit nor with deep scratches, and cleaned well with a good panell wipe...

it more the paint is very brittle really, but yes i'm sure the prep wasn't the best

with my axle, i sprayed white over the primer, that all stuck fine, gave the white 40mins to go tacky, then put the flouorecent orange over the top, and the orange flaked off, but not the white, not really sure what else i could have done there, except maybe spray the oragne a bit thicker

quote from my college lecturer years ago:-

"the quality of the end result will be dierctly proportional to the time and effort put in to the preperation of the car"

provide a good key, make sure that the panel/s are thoroughly degreased and bone dry. make sure that the temperature of the workpiece is the same as the air temp to prevent condensation during spraying and remember that several thin coats are better than one thick. thinning to the manufacturers guidelines should not be a problem (are you using the correct thinners?)

i still have all the paperwork from when i did the theory part of the course if you would like me to copy it and post it over to you? send U2U if you need them

Cheers SK

that would be awesome thanks

I am not aware of any wet on wet primer available for celly - perhaps this is your problem
