Sanding sealer compatibility with primer

[Marelton]

I've sanded my guitar body and neck and applied two coats of sanding sealer (shown below)

I went to get some primer today at a local paint supplier and the guy says to me "What type of sealer is it?", to which I replied, ...er...don't know
Now not sure if the auto paint I'm going to use (and still not sure which is best) is going to react with the sealer.

I asked the guy what would not be good and he said enamel. I'm sure it's not enamel, but still unsure if I'm going to have problems or not.
I've checked the MDS and it doesn't really help.

As usual, any advice would be appreciated.

It could be the water based vs oil based question being asked by the guy in the shop?

I know I talked to DB at one time about feast Watson when I used it under some clear gloss acrylic, it had very strong pink hue too, it crazed really badly I had to sand it off and start over. In the end I used Ubeauts sanding sealer which worked great can't say if it will be ok. I'd paint some on some wood then spray over the top see how it goes.

The ubeaut stuff is shellac based.

Thanks guys. As you say this is going to come down to trial and error as there is so much conflicting information out there.

This is my intention
1. Acrylic prime (dependant on the trial and error results with the sanding sealer)
2. Black acrylic base coat
3. Thin layer of low flec silver base coat over the black.
4 Marble effect silver base coat while wet with cling wrap
5. Cobalt blue candy over the silver/black marble effect (provided I can find a candy dye/pigment that mixes with acrylic clear coat)
6. Acrylic clear coat
7. Lots of wet and dry sanding and polishing.....job done

Anyway, that's the plan.

I've used Timbermate under auto acrylics with no drama

[Marelton]

Thanks Dedman, Timbermate looks like a filler though. I assume you dilute it to use as a sanding sealer?

[Dedman]

yup, I made a slurry mixing it with water.

Hi Marelton , Timbermate is used on certain woods that need their grains filling, this helps when you come to paint or spray the guitar it gives you a flatter finish of clear coat or paint. Again it depends on what wood you have. DB says he prefers natural timbermate as you can dye it to suit yourself as necessary.This might help https://youtu.be/Z9s_inRmcMo

Got it.

Picked some up this arvo from the big green place, the name of which I can't mention!

Do you think it will be ok to go straight over the sealer already on there? It's sanded back pretty well.
