| Re: Getting ready for paint what is best???? Changing color is no small task. You have a lot of work to do if this is going to look nice. think about the Door jambs, and underhood areas...
Surface Preparation is 95% of the battle in making a paint job look good. Poor surface preparation can not be hidden by a coat of paint. Paint just amplifies the surface preparation flaws. Fixing bad body work just doubles the effort...
I personally would get a quote from the shop. If you figure your time + materials + mistakes + tools I bet you'll find that the body shop may be the better/cheaper solution...
As a general rule, I never bring a car to the metal if the substrate is still intact and in good shape. First you will need to wash the car completely, and then go over it with a wax and degreaser product. Then begin to mechanically etch the surface on all the paint areas that have good adhesion and no appearance of rust. A red or green scotchbrite pad is usually sufficient, use it till you see the scratches on the substrate. A DA sander can be overkill for a beginner. All you need is sufficient surface agitation to allow the primer sealer to adhere.
Any area that is rusted should be brought down to bare metal with either a wire wheel or a dual action sander, feathering the edges outwards to blend into the surrounding with finer grits. 80/150/220 grit is usually sufficient here.
Use a metal conditioner product immediately on any bare metal after sanding to protect against more rust forming. After metal conditioner you would apply putty or lightweight body filler to the area. When sanding lightweight filler always sand on the diagonal, never straight. if you look at a clock, sand on the diagonal from 10 o'clock to 4 o'clock one way, then 2 o'clock to 7o'clock the other way.
Tools:
You will need things like a 2" rubber squeegee, a soft hand sanding pad, various hand sanding blocks (longer the better, 16", 12", 8" are good, and a da sander. Air or electric as you choose. you will also need a set of putty knives for spreading plastic body filler.
Materials:
you will want to buy wax/degreasing and bare metal conditioner products and have a good supply of tack cloths and shop rags/towels. I use a 2 part glazing compound and rage lightweight body filler because they dont shrink and sand nice. For larger repair areas you might need fiberglass reinforced filler if there is significant damage. If you metal condition bare spots you can hold off priming somewhat if the area is kept dry...
Then youll need primer surfacer and possibly sealing materials. Its usually best to seal the whole car after body work is complete if you are changing the color.
Always try to prime anything you bring to the metal ASAP after metal conditioning it. Make sure you know ahead of time what kind of paint the shop you will use uses. I personally use urethane whenever possible. lacquer based products are not desirable and may not be used under some products, so be careful and check first. I usually do a days worth of body work and finish up the last half hour by spraying any bare spots at the end of the day. |
