Can I use Kilz latex primer in a bathroom w/shower?

My fence is mostly horizontal rough wood with one section vertical planed wood and a vertical planed wood gate. It was painted by the previous house owners with a waterbased green stain. After 10 years in the house, It had faded a lot so I’ve repainted it with a Sadolin

New primed cedar shakes were installed. One coat of Benjamin Moore flat exterior latex paint applied. Within 1 hour–heavy rain came down. It was raining cream color (house was painted a beige color). No over hang, do we have to sand and prime? Question two- We had also oil primed

I need to know if I have to apply a oil base primer (on the already primed shingles from the factory) before I apply a solid color stain?

The temp is low 80’s and humidity is 61%. Is it OK to paint exterior walls?

We have a large (40 x 10) covered patio that is only one side open air, it has two ceiling fans up there, there is a 6″ wood edge along the top of the roof where the patio is open to the outside. There is a treatment on the ceiling

I just bought a wood grain, dark brown color fiberglass front door from HomeDepot. The HomeDepot guy told me to put a coat of “varnish” on the door but a painting contractor told me not to and just leave the door as it is because the varnish will wear out

I used Zissner 1-2-3 after removing wall paper. I was told that wasn’t the best choice – as an oil based primer is better. Should I top coat after a few days and hope there is no activation of wall paper residue OR take action to correct the problem first?

I have a house that has a light rust color roof and the house is colonial yellow, the door and shutters are light blue. What colors can I paint my house and shutters and door that would go with our roof?
