Do I need to wash car after compound/polish?

[Vortech5.0]

I first compounded with M105, now I'm going over it with 205. Do I need to wash or clean it more than just wiping it off before I put on a sealant? Thanks

105 dusts like crazy, so unless you like the dust in your way I say no. If you want to apply a sealant on a nice clean surface I say yes.

Its not necessary to wash the car after compounding/polishing just do a thoroughly IPA wipe down and you are good to go

I always do, although it may look excessive, I've done it once and became addict of finishing (applying LSP) to a just washed / thoroughly dried car.

I do it mainly for two purposes:

- getting rid of dust, if any,

- when washing a just polished car, I use a damp plush MF towel to wipe of everything that may be left in a safe way.


How I like it:

- Rinse with foam cannon and some hyper wash soap,

- fill the bucket with foam cannon to damp MF

- Pass the damp plush MF towel over every section just like 'final wiping polish residue'.

- Rinse thoroughly.

A just polished car will dry super fast using a good drying towel.

Then I use a blower (or vacuum) to get water out from inside crannies,

And apply LSP.

I like doing this, and it's very unlikely I will do differently because it's working very good.

Kind Regards.

Here are some pics that illustrate what I'm talking above:

This is from a Peugeot 307 (came some months earlier for AIO, but returned some months later for PBL coating).

I work till late most of time, so those are 'night shots'!


Foaming mainly to assist for dust removal.

This is the kind of towel I use most for this stage for the final damp wipe off:

Car dried and ready for LSP - getting rid of every bit of dust is a great feeling for me:
