Here is what a WA Resale Certificate states:

The buyer certifies that it is purchasing the items listed on line 6 (please check
appropriate box):
For resale in the regular course of business without intervening use.
For use as an ingredient or component part of a new article of tangible
personal property to be produced for sale,
as a chemical to be used in processing a new article of tangible personal
property to be produced for sale, or
for use as feed, seed, seedlings, fertilizer, or spray materials in its capacity
as a farmer.
The buyer acknowledges that it is solely responsible for purchasing within the
categories listed on line 6. The buyer acknowledges that misuse of the resale
privilege subjects the buyer to a penalty of 50 percent of the tax due, in addition
to the tax, interest, and any other penalties imposed by law.

Clearly none of those apply to a shop car not being sold in not paying sales tax and using the resale certificate. If WA State DOR decides to audit you, you will end up paying a lot more than the sales tax.

 

the same reason you wanted to see them post a dyno on the ark coilovers, I need to see visuals and a review of someone that has these on their car

 

seeing pics of a car that has these coilovers has absolutely nothing in common with shock dyno's or a review. you asked for pics, not a review...

 

sooo anyone create the review for these coils yet?!
