one thing ive learned the hard way is paint shrink !! it looks great and then a month later the paint cures in the sun and you start to see all the sand scratches , some body shops in buss for many years still dont know what they are doing wrong , the secret ??? stay away from lacquer based primers , yes they are easy to sand , but they also shrink the most later on , i now use 2 part primer surfacers . next . guide coat , guide coat as seen in the pic is used to find low and high spots BEFORE you paint and see all the flaws . spray it on light or heavy and then block sand in a crisscross motion , see the dark spots ??? they are low spots and would appeared wavy once painted , this part of my car was never damaged to my knowlage and when it was black i really didnt see it , but i want to look as good as it can so i will block this until its perfect . more later

to keep my sand paper from clogging up too much , i take a paint stick and smack the sand paper every few min of sanding , this keeps it clean and keeps it works as i sand , sand paper and everything else is expensive now a days so this keeps it lasting as long as it can . ( see pics )

#1 for areas that are rounded and compound curved i use a heater hose , left over from other repairs it conforms well to many areas ( see pic ) , #2 also to mask off tires i use large garbage bags , but keep in mind this is primering only , make sure to not have plastic where you are final coating , after one dry coat of paint on plastic it can dry and then flutter from the air of a paint gun and come loose and then into the next coat of new paint , ( see pic ) use paper or a old blanket to cover the plastic bag .

# 1 if you live in an area where its cold you need to know the true temp of what your working on or painting , it may feel warm in the garage but the true temp of your paint and the metal can be much different and effect dry times and so on , i use a non contact temp meter ( see pic ) there are better ones out there but i,m still using this one i bought for about 20 bucks . this is one of the many items that is critical to know and correct if its too cold . you can also use a heat lamp or infared lamp to help dry areas if needed .

it looks good again !!! now its time to make it look like crap again ( wet sanding )

RUNS !!! i had a run at the door handle , i guess i shot too much clear in there making sure i got clear up behind it , i take a new razor blade and at a 90 degree angle ( straight up ) i shave the run off untill its flat , then wet sand over it all , see pics .

i always ground my cars , i got lucky and i have a pipe running into the ground inside my garage , but its important to do this as it keeps down the static electricity and doing anything to keep down the dust in the paint will help , even in a paint booth some guys do this .

Also, warm paint flows better. I use a heating plate for about 5 minutes prior to spraying to warm the paint up to about 65 degrees.

Two wheels or Four, I'm happy as long as the throttle is pinned.

great info so far! How about painting a plastic piece, specifically the trunk latch cover. The piece that goes over the trunk release button and covers up where the license plate lights are? I would be using a can of spray paint.

i dont know exactly what part it is , but i used to work in a paint shop for GM and all the plastic parts came in black an we would paint them to the color of the car or truck , you need to find a can of plastic prep , its primer for plastic and then get paint for plastic , ( its normally lacquer based ) and paint away , let it dry over night and dont wax for at least a few weeks

painting tips

Speaking of oil-based paint, if the previous painter was foolish enough to use it, you must prime everything first, for latex paint will not stick to oil.
