It was an educated guess (still in the process of buying my first landy). I've seen it used to black out quite a few things (albeit on slightly more porous surfaces). But I would bow to Pos' superior experience as he seems to have tried it.
You can shoot ****e hawks if they're a pest to crops etc. Don't know if ****ting on yer landy counts thoughseagull ****e doesn't, winged vermin!!
Yes indeedy, keep it filthy and the pikey scum won't want to get their trackies dirty trying to get into it[Putting any sort of oil based product on plastic will accelerate the materials natural aging process and is likely to result in the early onset on brittleness and susceptibility to cracking.
Ive seen a 110 dash that was wiped over once a month with WD40 that has cracked and turned almost grey in color.
Why is eveyone so keen to smarten up their landies these days, you do know that if it's clean and shinny than the local tealeafs will find if of much greater interest.
