Undercoat of choice?

I've been using some Tecaloid synthetic enamel undercoat for the last 30
years for bits of bike - sidestands and the like. At the time I bought it
for use on a DT175 frame. I've just stirred it up for go at painting my KLE
sidestand. The tin started leaking from the bottom - I've decanted it off
into jam jars so I can finish this and a couple of other jobs. I think I
need to invest in another tin of undercoat (it'll probably see me out).
Paint technology has no doubt come on a bit since 1980.

The Tecaloid seemed to be suitable for any topcoat, wet and dried superbly
and went on quite thick. So what's the undercoat of choice today?

Tekaloid is / was a Croda product, no idea if they still make the stuff
though.

I would suggest you go to either your local auto paint factors for a
coach enamel type product, or your local agricultural machinery works,
as Tekaoloid was a favoured touch-up in various shades of JCB Yellow or
John Deere Green.

Another option would be something like Joseph Mason's coach enamel, you
may find this available at your local canal boat fettlement emporium.

 

It has, to the point where you don't need an undercoat.

None. Just use Hammerite, or if you want it to be indestructable,
POR-15 chassis paint.

 

Thanks for that, I was just wondering which paint to choose for my 100RS
sw-arm.

 

The POR stuff's amazingly tough. Just make sure you put plenty of
clingfilm over the top of the tin before putting the lid back on if you
ever want to get it open again.

Oh, & wear gloves. I didn't the first time I used it & it took weeks to
get off my hands. The only way was to pick at it until I couldn't take
the pain anymore, wait a few days for the skin to grow back then pick
some more.

 

Latex and clingfilm for a weekend it is then........
