Hello all,
I apologise if this topic has been covered enough already but I want to repaint my 400/4 engine during the Christmas break.
When I rebuilt the engine ~ a year ago I used the VHT paint that DSS stocks. My preparation was individually bead blasting each part and a solvent wash etc. The paint was applied as per instructions, only I omitted to bake the paint as our electrode oven was out of action at the time but his site suggested that it would cure under engine heating.
Fast forward around 3k miles and the paint looks quite poor in my opinion with some areas down to the bare metal and I'm still left with silver over my hands etc when handling/working the engine/bike at all.
I came across a high(ish) temperature aluminium/zinc paint that lidl was stocking (See attached) at £2.50 a tin. On other parts I've painted the paint seems pretty good, resists solvents, durable and doesn't require baking. However, the temperature of this paint is up to 250c.
Do you guys think this is high enough heat resistance? I also plan on using an etch primer on the parts but I am unsure if etch primer has a high enough service temperature, or whether or not i would be better off with/without it
The engine will be being painted assembled this time and I plan on gunk green washing, rub down with scotchbrite and giving it a good clean off with brake cleaner or some other degreaser.
I will also test this out on some scrap aluminium and put it in the now working electrode oven up to 250c
Thanks
