If you are priming bodywork, filler; be sure to finish all filler in 180 grit sandpaper, then feather edge paint starting with 180 grit, finishing with 320 grit. Thoroughly clean surface and mask accordingly. Apply corrosion protection and then prime. If you are going to prime a complet vehicle, be sure all nicks and scratches are feather edged with above method. The rest of the vehicle can then be sanded with 320 grit and primed with above method.
Get a really good primer.
Prep body, primer, paint, finish, let dry
I would sand it down with sand paper then paint with primer. After that apply a outdoor paint. Prep work should be smooth If you really want it to be nice hit the primer with a light sandpaper after the primer coat.
Yes it does. the different in the paint classifications relates to degrees of prep ie: primer surfacer, primer sealer, sanding proceedures, and additives (catalysts etc)
Any primer is going to seal the surface which is all the gesso is doing.
Yes you can repaint a car body there is prep work invalved with sanding and fixing rust and dents then there is primer and then the paint
The main issue here is prep of the oil based painted surface. Oil base paint is often in higher sheen levels which creates a slick surface. Sanding prior to painting latex over is always recomended. Also the use of a good oil based or bonding type primer, i dont mean the "paint and primer in one" i mean a primer made to be a primer. Your local paint store expert should be able to point you in the right direction. Nine times out of ten any problem can be prevented with proper surface prep this is the most critical step. Even if you sue an oil based primer you can still use latex paint on top. good luck
It won't stick if you didn't do something to prep the oil painted surface.
A prep deck for painting should include items such as sandpaper, painter's tape, drop cloths, cleaning supplies, primer, paint brushes, rollers, and paint trays. These tools will help prepare the surface and ensure a smooth painting process.
Yes, after ensuring that the surface is clean, oil-free and dull. Lightly sand the shiny surface to help the new paint adhere. Even though the paint is marketed as paint with primer, it still requires basic prep work prior to application.
Urethane primers are not not compatible with gelcoat, nor are epoxy primers. Gelcoat can only be applied to bare fibreglass, existing (well sanded) gelcoat or polyester/vinylester based fillers.
Use a good quality primer that is intended for all paints or for oil based paints. You might want to use a tintable primer (Killz for example), and have it tinted to approximate your final paint color. That gives much better chances of painting in one coat.
