Im doing my first paint job on my 91 hatch, Ive shot primer and wet sanded with 600 grit but ive got some high spots and a few edges where the origional paint is visible.


My question, will it be ok to shoot base and clear over this or will I have adhesion problems, is this normal. I was carfull as hell about not sanding to much.

 

you better make sure everything is covered with primer. Were those colors are coming through its likely you will end up with some type of bleed through or other problem. Trust me Ive had it happen on more than one occasion. Take the time and do it right so It will turn out 100%. Oh and 600grit is a lil bit to fine for sanding the primer, You need some surface for the paint to bite into.

 

Im sorry I forgot to add im spraying a sealant after primer and im painting it black
will I still have these problems. I was asking because this is my dd and i need to have this car finished this weekend

 

I'd have another coat of primer over that if you are sanding it, it looks like you easily sanded through the primer

And 600 is too fine

 

As much as it seems like you should sand directly on high spots it is neccesary to sand AROUND them to level out the rest of the door. then you should spray 1-2 light coats or primer and use a squeege when wet sanding to see the spots better.

 

you are fine....did you use a guide coat when you sanded the primer? spray a light coat of cheap laquor spray can primer(sandable) in a contrasting color and block sand the car with a large block in a X pattern till the spray can color is gone..you will see the lows(spray can color) sand till they are gone...previous paint coming through that is fine its the process you didnt have to prime the whole car it just helps level it all out from the repare areas...spray your sealer and paint....i like to paint/seal over 320 grit that 600 is fine i would go back over with 320 dry thats whay most paint manufactures reccomend if differnt use what the spec sheet says..i doubt its 600

 

no your def not fine. I do this for a living and you need to have one uniform surface or the thinner in the base can react differently with the old base coat compared to the primer and you will get serious issues. Trust me spend the extra hr and do it right.

 

Thanks for the help im going to sand the car down with 400 grit and ill shoot the spots with primer that are to low(previous paint showing).
thanks i will try this
yea a few spots I think I only put 2 coats of primer on I shot 3 but it was getting dark and the last coat i shot with a pen light it sucks but I needed to shoot primer that day or it was going to sit till the next weekend i can only work on the weekends on this projectet

I thank you guys for your help keep the tips rolling in and ill post a finished pic

 

won't the primer sealer give it uniformity?

 

sealer is just diluted primer. Its like putting on a watered down coat.
