What is the recommended best practice for reapplying glaze or body filler after using dry (or wet) guide coat? Is it necessary to completely remove any residual, i.e. will it potentially cause adhesion issues? Thanks for the videos!

i use ashes in ground in a coffee grinder with 1/8 part pure gray porland cement, works awesome, you can use fine powder plaster also as white 👍💯

Question ? When I reprime and or add a spot of glazing here and there does it hurt anything to bury the powder in the imperfections. I've cleaned with grease and wax remover but it doesn't get it all off.

I have this same question.

If I'm using a black high build primer should I use white guide coat?

@3MCollision 3 ай бұрын

Yes, when using a black high build primer, it is recommended to use a white guide coat. The purpose of a guide coat is to provide a contrasting colour that helps you identify any imperfections or low spots in the surface you are priming.

I'm curious if you need to do this if you take everything down to bare metal with something aggressive like 40/60/80 grit sandpaper and then want to prime with epoxy primer and paint in one step essentially without sanding the primer in between?

@PhillipsTravels 10 ай бұрын

You should sand the epoxy primer to at least 600 grit once dry, and should allow it to dry. I haven't seen an epoxy primer that recommends wet-on-wet...

@@PhillipsTravels @00dibrah Interesting. All the epoxy primer's I've looked at or used have a 5-7 day top coat window. After that time sanding would be required in order to top coat. I've just never really painted anything with it that would matter what it looked like after everything was finished. I want to avoid sand scratches showing through the final product if I don't sand the bare metal with some finer sand paper before priming and painting. I'm ok with sanding if I have to, but it would be ideal if I can get an adequate final finish without sanding. Dunno if I articulated what I'm trying to do well enough. 😂
