Lacq thinner isn't to make it sand any easier, It's to clean any wax and grease off before you sand.

 

oh ok i see works like a wax and grese remover but only cheaper thx for the tips.i also wanna wash the car down really good before i do anything.

 

That's a great idea! Too many people don't get things clean before they start bodywork, and then forget to do so later. Then it affects the paint and they blame the paint shop. Washing and cleaning first eliminates a lot of possible issues later.

 

yeah also if u start sanding before cleaning it ur just grinding all that wax and grease into the metal,then they wonder why the paint is peeling off a year later.this car looks like it hasnt been washed in years probably would look really nice with just a scrub down,dawn dish soap seems to work really good for me takes alot of the oils and grease off,i have also used windex it works great to remove grease and wax also.

 

i have another question what about scratches and stuff on my bumper covers theres no rips or anything but can we use lightweight filler on them .aplly a guide coat then just sand it all off and no more scratches.

 

There are products used to paint urethane bumpers, and also products to fill the scratches. Don't use anything on the bumper to repair or paint that isn't designed for the plastic, or it wont hold.
You only get one chance to do the body and paint right, and it's the thing everyone notices when they first see your car.

 

yeah thats why i wanna make sure i get it perfect the first time,i have the flex additive for my paint and just found out that evercoate makes a polyflex filler designed just for urethane bumper covers,surely wouldnt wanna do this twice thsts why im asking so many questions dont wanna screw it up.

 

That's why I chickened out on painting my Austin or my Camaro. I just didn't want to do all that prep work and then screw up the paint. Glad I left them both to pros, as they came out much better than I could have done!

 

i have a set of door panels in excellent condition there the early style 2 piece ones that doesnt have them ugly pull handles that always come apart will they work on my 79 doors.

 

They can be forced to work. The inner handle area of the door changed with the door panels.
